Summary of the Article: Converting CO2 to CO and Understanding the Differences
1. Conversion of CO2 to CO:
In the process of converting CO2 to CO, solid carbon binds to one oxygen atom in carbon dioxide, reducing it to carbon monoxide. This conversion requires a significant amount of energy, typically in the form of high heat.
2. Harmfulness of CO2 and CO:
Carbon monoxide gas is considered more dangerous than carbon dioxide gas.
3. Detection of CO2 and CO:
CO2 detectors usually use infrared sensors to detect gas levels, whereas CO detectors primarily rely on electrochemical sensors.
4. Reasons for CO Production:
CO is often produced instead of CO2 during incomplete combustion. This can occur when there is insufficient oxygen or excessive carbon present during the burning process.
5. Conversion of CO to CO2:
CO can be converted to CO2 on metal-oxide catalyst surfaces that have oxygen vacancies. However, when these vacancies become filled, the surface becomes deactivated for the reaction.
6. Comparison of CO and CO2 Toxicity:
The concentration at which CO becomes life-threatening is much lower than that of CO2. While 35 ppm (0.4%) of CO is quickly life-threatening, it takes more than 30,000 ppm (3%) of CO2 to reach the same risk level.
7. Deadliness of CO compared to CO2:
Carbon monoxide is deadlier than carbon dioxide because it is poisonous and forms a stable complex with blood, specifically with haemoglobin.
8. Distinction between CO2 and CO Alarms:
The detection of CO2 and CO differs in the sensors used. CO2 detectors commonly employ infrared sensors, while CO detectors primarily rely on electrochemical sensors.

How do you convert CO2 to CO
In this reaction, solid carbon latches onto one of the oxygen atoms in carbon dioxide gas, reducing it to carbon monoxide. The conversion normally requires significant amounts of energy in the form of high heat — a temperature of at least 700 degrees Celsius, hot enough to melt aluminum at normal atmospheric pressure.
Is CO2 or CO more harmful
Carbon monoxide gas is more dangerous than carbon dioxide gas.
Does a CO2 detector detect carbon monoxide
Can you Detect CO with a CO2 Detector The answer is no. CO2 detectors often use infrared sensors to detect levels of gas, while CO sensors main use electrochemical sensors.
Why is CO produced instead of CO2
Carbon monoxide is often a product of incomplete combustion. If there is too little oxygen, or too much carbon, present when something burns, the burning produces carbon monoxide (CO) instead of (or as well as) carbon dioxide (CO2).
Can we convert CO to CO2
On metal–oxide catalyst surfaces with oxygen vacancies, CO is readily converted to CO2. When the oxygen vacancies become filled, the surface is deactivated for the reaction. Gray = metal (platinum); blue = oxide (cobalt oxide); red = oxygen; black = carbon.
Why is CO worse than CO2
While both CO and CO2 are potentially deadly, this happens at vastly different concentrations. While 35 ppm (0.4%) of CO is quickly life threatening, it takes more than 30,000 ppm (3%) of CO2 to reach the same risk level. Compressed carbon dioxide and carbon monoxide are both important industrial gases.
Why is CO deadlier than CO2
Carbon monoxide is poisonous and carbon dioxide is non toxic in nature. Carbon monoxide is poisonous because it has the capacity to form a complex with blood as in haemoglobin. And the complex of carbon monoxide with haemoglobin is more stable than the complex of oxygen with haemoglobin.
What is the difference between CO2 and CO alarms
Carbon Dioxide and Carbon Monoxide Sensing – What's The Difference The detection of the two gases differ because CO₂ detectors commonly use infrared sensors, while CO identification uses electrochemical sensors. However, CO can also be detected using NDIR sensing.
What triggers a CO2 detector
CO alarms are designed to warn you of any unusual build-up of CO in your home. These higher levels of CO may occur from improperly maintained, installed or used fuel-burning appliances, backdrafting appliances or fireplaces, or idling cars in garages.
Why is CO bad for the atmosphere
When carbon monoxide is emitted into the atmosphere it effects the amount of greenhouse gases, which are linked to climate change and global warming. This means that land and sea temperature increases changing to ecosystems, increasing storm activity and causing other extreme weather events.
Why is CO2 better than CO
The most important difference is that carbon dioxide is a common, naturally occurring gas required for plant and animal life. CO is not common. It is a byproduct of the burning of fossil fuels such as oil, coal, and gas. CO poisoning occurs when carbon monoxide builds up in your bloodstream.
How is CO2 reduced to CO
CO2-to-CO conversion involves only two-electron/proton transfer and thus is kinetically fast. Among the various developed CO2-to-CO reduction electrocatalysts, transition metal/N-doped carbon (M-N-C) catalysts are attractive due to their low cost and high activity.
Is 1500 ppm CO2 safe to breathe
The levels of CO2 in the air and potential health problems are: 400 ppm: average outdoor air level. 400–1,000 ppm: typical level found in occupied spaces with good air exchange. 1,000–2,000 ppm: level associated with complaints of drowsiness and poor air.
Will CO2 knock you out
Concentrations of more than 10% carbon dioxide may cause convulsions, coma, and death [1, 15]. CO2 levels of more than 30% act rapidly leading to loss of consciousness in seconds.
How common are CO2 deaths
Every year, at least 430 people die in the U.S. from accidental CO poisoning. Approximately 50,000 people in the U.S. visit the emergency department each year due to accidental CO poisoning.
Do I need a co2 alarm in my house
Where do carbon monoxide alarms need to be located The regulations do not stipulate where the alarms should be placed. A carbon monoxide alarm should be installed in every room which is used as living accommodation containing a fixed combustion appliance (excluding gas cookers).
How many co2 detectors should a house have
The International Association of Fire Chiefs recommends a carbon monoxide detector on every floor of your home, including the basement. A detector should be located within 10 feet of each bedroom door and there should be one near or over any attached garage. Each detector should be replaced every five to six years.
What causes co2 to spike in house
Sources of CO2 in indoor air
Carbon dioxide is a pollutant found in indoor and outdoor air. Indoors, CO2 is mainly produced through the respiration (breathing) of occupants, but can also come from: cigarette smoking. unvented or poorly vented fuel-burning appliances.
Why does my co2 detector go off for no reason
There are several reasons you might get a false alarm from your CO detector. Your CO detector needs to be replaced. Detectors can malfunction near the end of their life span. Your system detects a carbon monoxide leak from one of your neighbor's appliances.
Why is exposure of CO harmful to us
Carbon monoxide is harmful because it binds to hemoglobin in the blood, reducing the ability of blood to carry oxygen. This interferes with oxygen delivery to the body's organs. The most common effects of CO exposure are fatigue, headaches, confusion, and dizziness due to inadequate oxygen delivery to the brain.
Why do we convert CO to CO2
The conversion of carbon monoxide (CO) into carbon dioxide (CO2) is important for cleaning up exhaust gases—mostly from vehicles that burn fossil fuels but also from stationary sources such as power plants and refineries.
What level of CO2 is toxic to humans
around 40,000 ppm
This could occur when exposed to levels above 5,000 ppm for many hours. At even higher levels of CO2 can cause asphyxiation as it replaces oxygen in the blood-exposure to concentrations around 40,000 ppm is immediately dangerous to life and health. CO2 poisoning, however, is very rare.
What is the acceptable CO2 level in a house
The American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) currently recommends that CO2 levels be maintained below 1,000 ppm.
What kills you carbon dioxide or monoxide
Carbon monoxide (CO) is a gas that can kill you quickly. It is called the “silent killer” because it is colorless, odorless, tasteless and non- irritating.
What causes high CO2 levels in house
High CO2 levels, generally over 1000 ppm, indicate a potential problem with air circulation and fresh air in a room or building. In general, high CO2 levels indicate the need to examine the HVAC system. High carbon dioxide levels can cause poor air quality and can even extinguish pilot lights on gas-powered appliances.
