氢是一种无污染、易储运的新能源.水分解制氢,由于其原料易得,受到人们的重视.但由于液态水分解为气态氢和氧,是一个相当强的吸热反应,用热分解的方法,需要2000°K以上的高温,其现实性是很小的.如果引入催化剂,则反应条件大为缓和.常用的方法主要是热催化和光催化. 三价钛在酸性水溶液里同水反应放氢在热力学上是有利的.但在通常条件下,这
Hydrogen is a kind of new energy which is non-polluting, easy to transport and transport.Hydrolysis of hydrogen, due to its easy availability of raw materials, attracts people’s attention.But because liquid water is decomposed into gaseous hydrogen and oxygen, it is a rather strong endothermic reaction, Thermal decomposition method, the need for more than 2000 ° K high temperature, its reality is very small .If the introduction of the catalyst, the reaction conditions greatly ease the commonly used methods are mainly thermal catalytic and photocatalytic trivalent titanium in acidic aqueous solution Hydrogen rehydration with water is thermodynamically favorable, but under normal conditions this is
