用于催化硼氢化钠氧化的非晶态球壳NiFeP催化剂研究
Research on amorphous hollow sphere NiFeP catalyst for borohydride oxidation reaction
摘要
Abstract
Direct borohydride fuel cell(DBFC)has been widely concerned due to their high energy density and safety.However,the development of efficient and cost-effective anode catalysts for DBFC remains a critical challenge.An amorphous NiFeP catalyst with a hollow sphere structure was synthe-sized on a nickel foam substrate and the morphology and electrochemical properties.The results dem-onstrate that the catalyst achieved a peak current density of 300.7 mA/cm² during the borohydride oxidation reaction(BOR).When applied to a DBFC system,the peak power density reached 621.3 mW/cm².The excellent BOR performance can be attributed to the enhanced intrinsic catalytic activ-ity resulting from the highly efficient active sites in the amorphous species,as well as the large spe-cific surface area provided by the three-dimensional hollow sphere structure.关键词
