What catalyst is used to convert CO to CO2?

For carbon monoxide gas, I believe we are all too familiar, the well-known writer Qiong Yao is because of carbon monoxide poisoning just "lightly" passed away, know that its toxicity is very strong, caused great harm to the human body and the environment. In order to solve this problem, carbon monoxide catalyst came into being, caring to protect us.

What principle does carbon monoxide catalyst use to eliminate carbon monoxide gas? It is to oxidize, reduce or hydrogenate the harmful components of carbon monoxide into harmless carbon dioxide, water or other low-harm substances.

Carbon monoxide catalyst has a broad prospect, with the continuous progress of technology, I believe that in the future there will be production of higher performance, low-cost carbon monoxide catalyst, to make greater contributions to environmental protection.
