摘要: 由于传统商用电催化析氢催化剂具有成本高、储量低等缺点,开发一种经济、高效、稳定的新型电催化析氢催化剂尤为重要。通过在泡沫镍基底上,使用诱导挥发自组装和浸渍-提拉法制备了负载钌的多孔TiO2催化剂,并应用于光辅助电催化析氢。其中钌和介孔TiO2之间的金属-载体效应可以有效提高电催化析氢反应(HER)的性能。在光的辅助下,生长在泡沫镍上的负载钌的多孔TiO2电催化剂在碱性电解液中表现出良好的电催化活性,当过电位为100 mV时,样品具有124 mA·cm-2的高电流密度,相同过电位无光环境下的样品的电流密度为102 mA·cm-2,在光照的辅助下,相同过电位的电流密度提升了约215 %

Abstract: Traditional commercial electrocatalytic hydrogen evolution catalysts have disadvantages such as high cost and low reserves. Therefore, it is still necessary to develop an economical, efficient and stable new electrocatalytic hydrogen evolution catalyst. Herein, the paper developed a photo-assisted electrocatalytic hydrogen evolution based on Ru-doped porous TiO2film catalyst grown on nickel foam prepared through evaporation-induced self-assembly and impregnation strategy. Ru and mesopores TiO2 structure could efficiently improve the performance of electrocatalytic hydrogen evolution reaction (HER). Under the assistance of light, the electrocatalyst of Ru-supported porous TiO2 on NF exhibits good electrocatalytic activities in basic condition with a high current density of 124 mA·cm-2at an overpotential of 100 mVwhich show 215% improvement over that under dark environment (102 mA·cm-2 at an overpotential of 100 mV).
