摘要: 随着世界经济格局的不断构建,保护环境与开发经济资源两者的矛盾也逐步凸显出来,要想使经济和环境达到协调的发展状态,必须要对新兴能源进行开发和利用。在进入现代以来,氢能被人们所发现,这种物质不仅可以应用在多种经济领域,而且还能够达到不污染环境的效果,氢能的提取过程需要依托电解反应,电解过程又离不开Pt系贵金属,但是这种金属开发起来非常困难,将其应用在电解过程中也需要较多的前期投入。为了改变这种现状,必须寻求新的催化剂来提高电解反应效率,其中,金属硫化物就是这样一类应用前景广阔的新型析氢材料。作为析氢反应中的催化剂,Fe7S8纳米粒子具有良好的电化学活性。

Study on the using of metal oxides to prepare metal sulfides for electrocatalytic hydrogen evolution
Abstract:In twenty-first Century, human beings were faced with two major problems - energy shortage and environmental pollution. One of the effective ways to solve these problems is to develop a clean and efficient new energy - hydrogen energy. The use of electrolyzed water or optoelectronic water to prepare hydrogen can not only make the whole process green economy, but also effectively realize the mutual conversion and utilization of energy. Although the best catalyst for electrolysis is Pt noble metal, but because of its high price and low earth reserves, it is difficult to be applied to large-scale production. Developing alternative catalysts is of great importance for the whole electrolysis or photoelectric water splitting industry. Metal sulfide is a new type of hydrogen evolution catalyst material with wide application prospects. As a catalyst in the hydrogen evolution reaction, FeS2 nanoscale has good electrochemical activity.
