Abstract

Iron ions play a critical, but yet unclear, role in improving the activity of Ni-based catalysts. To investigate the changes of iron ions doping in photocatalytic properties, we prepared undoped and Fe doped nanosheet-assembled Ni₃(NO₃)₂(OH)₄ spheres and particles by a simple hydrothermal method, which used urea to provide OH^–. The effects of the iron ions and urea on the preparation of the Ni₃(NO₃)₂(OH)₄ structures were explored. In the presence of Fe, low concentration of urea favors the formation of Ni₃(NO₃)₂(OH)₄ particles, while high concentration prefers the formation of well-crystallized nanosheet-assembled Ni₃(NO₃)₂(OH)₄ spheres. Without Fe doping, only nanosheet-assembled Ni₃(NO₃)₂(OH)₄ spheres were obtained and more urea resulted in the formation of poor-crystallized Ni₃(NO₃)₂(OH)₄ spheres. Fe doped nanosheet-assembled Ni₃(NO₃)₂(OH)₄ spheres and particles with holes on the surface exhibited good photocatalytic activity in the degradation of methyl orange.
