摘　　要：Ni2P纳米材料特殊的结构使其在催化领域显示出优异的活性和稳定性。作为催化材料,Ni2P的催化性能主要依赖于其结构、形貌及尺寸大小,实现Ni2P纳米材料的可控合成将是催化材料领域研究的热点。综述了Ni2P纳米材料的控制合成方法、合成机理及其在催化性能方面的研究进展,讨论了Ni2P纳米材料的应用前景,并从电子结构层次对Ni2P催化性能做了定性解释。Ni2P结构中由于P原子的掺入使得"d空穴"增多,费米能级附近的态密度增加,表现出类贵金属的特性,具有很好的催化性能。Ni2P纳米材料的催化脱氢性能将是继加氢性能之后又一个崭新的应用领域。Ni2P nanomaterials persent excellent activity and stability in catalytic field because of the special structure.As the catalytic materials,the catalytic performance of Ni2 P mainly depends on the structure,morphology and size,the controllable synthesis of Ni2P nanomaterials will become a hot topic in the field of catalytic materials.Recent progress in the controllable synthesis method of Ni2P nanomaterials,synthesis mechanism and catalytic performance are reviewed,the application prospect of Ni2 P nanomaterials is discussed,and the relationship between the electronic structure and catalytic performance of Ni2 P nanomaterials is also explained qualitatively.Ni2 P show good catalytic activity because it has samillar characteristics with noble metal due to the incorporation of P atom,which increased the ＂d hole＂ and the density of states near the Fermi level.The catalytic dehydrogenation performance of Ni2P nanomaterials will become a new application field after the hydrogenation performance.
