杂原子掺杂碳基氧还原反应电催化剂研究进展
Recent progress on electrocatalysts towards oxygen reduction reaction based on heteroatoms-doped carbon
摘要
Abstract
Electrochemical oxygen reduction reaction (ORR) is key to clean and sustainable energy technologies including proton exchange membrane fuel cells and metal-air batteries. However, the high-activation barriers in ORR often makes it the bottleneck of energy conversion processes, and thus high performance ORR electrocatalysts are desired. At present the best commercially available ORR catalyst is based on the precious metal Pt. But it suffers from resource scarcity and unsatisfactory operational stability, thus hindering a widespread and large-scale application of the clean and sustainable technologies. To tackle this problem, extensive efforts have been made in the last decade or so to search after efficient non-precious metal ORR catalysts. Among these, many heteroatoms-doped carbon (HDC) materials appear to be very promising, owing to their easy availability, low cost and excellent electrochemical performance. In this review article, recent advances in this active area are summarized, with the content being categorized according to the different underlying mechanisms of doped heteroatoms. Theoretical and experimental findings regarding HDC materials in ORR catalysis are reviewed, emphasizing the influence of heteroatom doping on the electronic structure of carbon materials. The problems facing HDC based ORR catalysts and further researches required are also discussed.关键词
