Phase separation synthesis of trinickel monophosphide porous hollow nanospheres for efficient hydrogen evolution

Jin, Lihuang; Xia, Han; Huang, Zhipeng; Lv, Cuncai; Wang, Jie; Humphrey, Mark; Zhang, Chi


A facile and scalable approach to synthesize trinickel monophosphide (Ni₃P) porous hollow nanospheres (PHNs) has been developed, the resultant Ni₃P PHNs exhibiting excellent catalytic activity in the hydrogen evolution reaction (HER). The formation of the Ni₃P PHNs correlates with phase separation during the thermal annealing of amorphous nickel–phosphorus nanospheres that affords crystalline Ni–Ni₃P nanoparticles, and the subsequent selective removal of nickel. The overpotential required for...[Show more]
