Synthesis of high-efficiency and low-cost electrocatalysts for oxygen reduction reaction (ORR) is currently one of the main targets for the commercialization of fuel cells. In this work, a non-traditional N...
In order to reduce the cost of the catalysts for the anion exchange membrane fuel cell (AEMFC), phosphorus-doped XC-72 carbon catalyst was prepared by one-step carbonization using XC-72 carbon and triphenyl phosphorus (TPP) as carbon source and phosphorus source. The structure, morphology and electrochemical performance of the phosphorus-doped carbon catalyst were evaluated by physical characterization and electrochemical methods. When the proportion of triphenyl phosphorus and XC-72 is 1:5, and carbonization temperature is [Formula: see text], the obtained catalyst shows mesoporous structure formed by the accumulation of nanospheres and exhibits better electrochemical performance, including more positive onset potential (−0.12 V), the largest current density [Formula: see text], which is slightly equal to commercial 20%Pt/C [Formula: see text]. Moreover, P is doped in carbon with C–P and O–P bond, which provide active sites to improve electrochemical performance. Low cost precursor and facile preparation of P-doped C is a candidate for full cell catalyst.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
