Self-supporting copper phosphide hydrogen evolution catalyst as well as preparation method and application thereof

The invention belongs to the technical field of catalysts, and particularly relates to a self-supporting copper phosphide hydrogen evolution catalyst and a preparation method and application thereof. The self-supporting copper phosphide hydrogen evolution catalyst provided by the invention is foamed copper phosphide with nano micropores distributed on the skeleton surface, the nano micropores greatly increase the specific surface area of the foamy copper, and active sites can be provided during hydrogen evolution reaction, so that the hydrogen evolution reaction performance of the catalyst is improved, and the hydrogen evolution efficiency of the catalyst is improved. The technical problem that the hydrogen evolution performance of a copper hydrogen evolution catalyst in the prior art needs to be improved is solved. 本申请属于催化剂技术领域，尤其涉及一种自支撑磷化铜析氢催化剂及其制备方法和应用；本申请提供的自支撑磷化铜析氢催化剂为骨架表面分布纳米微孔的泡沫磷化铜，纳米微孔极大的增加了泡沫铜的比表面积，能在析氢反应时提供活性位点，从而提高催化剂的析氢反应性能，解决现有技术中铜析氢催化剂的析氢性能还有待提高的技术问题。
