析氫電極電催化活性的調(diào)控 由于化石燃料不可再生以及人類無限制開采，化石燃料終將會(huì)枯竭。與此同時(shí)，大量化石燃料的燃燒也對環(huán)境造成了巨大危害。因此，積極研發(fā)清潔可持續(xù)的替代能源迫在眉睫。氫氣因其熱值高、清潔和可再生等優(yōu)點(diǎn)成為各國研究的重點(diǎn)。氫元素是地球上最豐富的元素，然而氫元素多以化合物的形式存在于水中。電解水或者光解水是較為有前景的制氫方法。制備清潔無污染廉價(jià)且催化效率優(yōu)異的析氫電極成為該領(lǐng)域最重要研究課題。 目前，析氫反應(yīng)的催化劑中效率最高的依然是貴金屬鉑及其復(fù)合材料。世界各國科研人員正在積極研制各種鉑復(fù)合材料電極，并且取得了一定的進(jìn)展。本研究同樣可以改善其他電極材料的電催化活性,為設(shè)計(jì)更高效的析氫催化劑提供了一個(gè)新的思路。 關(guān)鍵詞：氫還原催化劑，光沉積，TiO2納米管  謝謝咯 |

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 |
