摘要：
In this letter, Ni2+ doped InVO4 nanocrystals were successfully synthesized by a simple one-pot microwave-assisted method. The energy bandgap of obtained samples can be precisely controlled by varying the Ni2+ doping amount. The O-2 production rate of obtained Ni-InVO4 nanocrystals is higher than that of pure InVO4 nanocrystals under visible-light, which can be ascribed to the narrowed band gaps. The corresponding 1% doped sample N1 has the highest O-2 production rate (394 mu mol/h) in all samples, which is 66% higher than the undoped sample NO. (C)2014 Elsevier B.V. All rights reserved.
