Anode catalyst for alkaline system direct urea fuel cell and preparation method thereof

The invention relates to an anode catalyst for an alkaline system direct urea fuel cell, which is a simple substance nickel/nickel oxide/nickel boride nanocrystalline composite material wrapped by a nitrogen-containing carbon material obtained by dispersing nickel salt, H3BO3 and PVP (Polyvinyl Pyrrolidone) in water, heating and reacting to prepare a precursor and then calcining in an inert atmosphere. Nonmetal boron and a PVP carbon material are introduced, an active substance nickel/nickel oxide/nickel boride is obtained after calcination to replace traditional precious metal, the electronic structure of the catalyst is adjusted by forming metal boride and oxide, the catalytic activity and the electrode conductivity of the catalyst are improved, the catalyst serves as an alkaline system to directly serve as an anode catalyst for a urea fuel cell, and the service life of the anode catalyst is prolonged. The electrochemical reaction activity is excellent. 本发明涉及一种碱性体系直接尿素燃料电池用阳极催化剂，是以镍盐、H3BO3和PVP分散于水中加热反应制备前驱体
