WebJun 17, 2024 · The primary goal of eliminating CO is to meet the stringent requirements of PEMFCs, which require CO levels below 50 parts per million ( 3 ). It is challenging for typical catalysts to achieve 50% O 2 selectivity (to CO 2) with complete CO conversion because of the competitive oxidation of H 2 ( 3 ). WebThis study demonstrates excellent control of the product selectivity property by regulating the catalyst composition with P anions and provides mechanistic discussions, which …
