ACS Appl Mater Interfaces. 2016 Dec 27. doi: 10.1021/acsami.6b14440. [Epub ahead of print]In this work, we propose a one-step process to realize the in-situ evolution of molybdenum carbide (Mo2C) nanoflakes into ordered mesoporous carbon with few-layered graphene walls (OMG) by chloridization and self-organization, and simultaneously the Cl-doping of OMG (OMG-Cl) by modulating chloridization and annealing processes is fulfilled. Benefiting from the improvement of electroconductivity induced by Cl-doping, together with large specific surface area (1882 cm2 g-1) and homogeneous pore structures, as anode of LIBs, OMG-Cl shows remarkable charge capacity of 1305 mAh g-1 at current rate of 50 mA g-1 and fast charge-discharge rate within dozens of seconds (a charge time of 46 s), as well as retains a charge capacity of 733 mAh g-1 at a current rate of 0.

International Journal of Hydrogen Energy, 2016, 41(46): 21246-21250.The rational design of cost-effective and high-activity electrocatalyst for hydrogen evolution reaction (HER) is a crucial field of research for achieving the best way to promote “green energy”. Here, the authors develop a simple route to prepare nanohybrids of threedimensional graphene loading MoO2-Mo2C nanoparticles (MoO2-Mo2C/G), which were characterized using X-ray diffractometer (XRD), BrunauereEmmetteTeller (BET), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), demonstrating the MoO2-Mo2C/G has unique features with high conductivity, robust structure, and high surface area.
