过渡金属基析氢催化剂研究进展

Research progress of transition metal-based hydrogen evolution catalysts

为了应对和解决能源与环境危机问题,氢能作为一种可持续再生的清洁能源,受到科技工作者的广泛关注。因此,氢气的制备问题成为研究热点,其中电解水制氢不依赖化石燃料且可利用过剩的太阳能、风能和电能驱动,被广泛研究。然而,不论是光解水还是电解水均需要高活性、高稳定性的非贵金属催化剂使得水分解反应高效且经济。基于此,文中总结了近几年来过渡金属磷化物、氮化物、碳化物、硒化物和硫化物在析氢方面的报道,展望了水电解非贵金属催化剂所面临的挑战和机遇。

In order to cope with and solve the energy and environment crisis,hydrogen energy as a kind of sustainable renewable clean energy,has received wide attention from scientific and technological workers.Therefore,the problem of hydrogen preparation became a hot research issue,among which the electrolysis of water to produce hydrogen,which is not dependent on fossil fuels and can be driven by excess solar,wind and electrical energy,was widely studied.However,both photolysis and electrolysis of water require highly active and stable non-precious metal catalysts to make the hydrolysis reaction efficient and economical.Based on this,the reports of transition metal phosphides,nitrides,carbides,selenides and sulfides in hydrogen precipitation in recent years were summarized,and the challenges and opportunities for non-precious metal catalysts for water electrolysis were looked at.
