摘要
能源危机是当今世界所面临的重大危机,目前,人类所依赖的能源仍然是化石燃料,可是,化石燃料是一种不可再生的能源,并且还会导致空气污染和全球变暖。因此,发展一种清洁,可再生能源是十分必要的~1。而氢气是很好的能源之一,并且氢气来源丰富,通过电化学分解水是目前研究的热点。铂基催化剂在酸性介质中是产氢最好的催化剂,但是由于地壳中铂含量少以及价格昂贵,所以限制了这类催化剂的广泛应用。目前,有必要寻找一种非贵金属催化剂或者是非金属催化剂来代替贵金属催化剂,既可以降低成本又可以达到很好的催化效果。我们通过一步法制备了在铜网上生长自负载的磷化铜结构用于分解水。
Strong dependence on fossil fuels has made our economy susceptible to price spikes, and overuse of fossil fuels is also intensifying air pollution and global warming. Thus, developing a clean, renewable alternative to fossil fuels is a matter of utmost urgency. Platinum-based catalysts are the best catalysts for hydrogen production in acidic medium, but because of the low content of platinum in the earth and the expensive price, so limiting the wide application of this kind of catalyst. We have prepared a self-supported copper phosphate structure for water splitting.
