摘要
Catalytic conversion of carbon monoxide (CO) is one of the most important process for human health protection. CO is also called the unnoticed poisons and silent killer of 21st century. The effect of inhaling CO can cause of hypoxic injury, neurological break and even death. Due to CO poisoning decay vegetation life and increases in global warming and ozone layer depletion. CO is produced into the environment by partial oxidation of carbon containing compounds. The main source of CO emission is the transportation sector. Thus, the oxidation of poisonous CO to nonpoisonous CO2 at ambient conditions is crucial for life conservation in many applications. Further, low-temperature CO oxidation is vital in minimizing emissions at the cold start of an internal combustion engine. A variety of CO oxidation catalysts are investigated in this era, but a maximum of them have problems associated with the deactivation in presence of moisture, cost-effective, lower stability, poison resistance, availability in the world. These accelerate the investigation of CO oxidation over various catalysts. Although there are numerous research articles present on this topic until now no one review are present for this demanding issue. So there is a space in this area, it has been made an attempt to seal this hole by this review. © 2019
