Received in revised form 10 January 2017 Herein, the nitrogen-doped three-dimensional reduced graphene oxide (N-3DrGO) catalysts have been Accepted 20 January 2017 prepared by a facile hydrothermal method using the raw materials of GO, melamine and formaldehyde. Available online 23 January 2017 The N contents in N-3DrGO products vary from 3.12 to 9.69 at.% which can be easily regulated by adjusting the feed mass ratios of GO and melamine. It is found that a higher content of N does not necessarily result in Keywords:
