析氢电极电催化活性的调控 由于化石燃料不可再生以及人类无限制开采，化石燃料终将会枯竭。与此同时，大量化石燃料的燃烧也对环境造成了巨大危害。因此，积极研发清洁可持续的替代能源迫在眉睫。氢气因其热值高、清洁和可再生等优点成为各国研究的重点。氢元素是地球上最丰富的元素，然而氢元素多以化合物的形式存在于水中。电解水或者光解水是较为有前景的制氢方法。制备清洁无污染廉价且催化效率优异的析氢电极成为该领域最重要研究课题。 目前，析氢反应的催化剂中效率最高的依然是贵金属铂及其复合材料。世界各国科研人员正在积极研制各种铂复合材料电极，并且取得了一定的进展。本研究同样可以改善其他电极材料的电催化活性,为设计更高效的析氢催化剂提供了一个新的思路。 关键词：氢还原催化剂，光沉积，TiO2纳米管  谢谢咯 |

Control of electrocatalytic activity of hydrogen producing electrode Since fossil fuels are not renewable and human uncontrolled exploitation, fossil fuels will eventually dry up. At the same time, the combustion of fossil fuels has caused great harm to the environment. Therefore, the need for developing clean and sustainable alternative energy is imminent. Hydrogen has become the focus of research because of its high calorific value, clean and renewable features. Hydrogen is the most abundant element on the earth, but hydrogen is mostly in the form of compound and present in water. Electrolysis or photolysis of water is a promising method for hydrogen production. How to make clean, nonpolluting, cheap hydrogen producing electrode with superior catalytic efficiency is the most important research project in the field. Currently, the most efficient catalyst for hydrogen production is still the noble metal platinum and its composite materials. Scientists in the world are actively developing a variety of platinum composite electrodes, and are making progresses. This study showed that we can also improve the electrocatalytic activity of other electrode materials, and provide a new idea for designing more efficient hydrogenproducing catalyst. Keywords: hydrogen reduction catalyst, photo deposition, TiO2 nanotubes |
