| 英文摘要 | Here we report a novel one-pot approach to synthesize MoCxcatalysts at much lowered temperature for hydrogen evolution reaction (HER) in acidic solution. A room-temperature co-precipitation reaction among Ni2+, MoO42−and 2-methylimidazole in an aqueous solution produced a Mo−Ni−imidazole complex, which was used as the precursor to fabricate MoCx. The morphological and chemical properties of the obtained MoCxaffected by calcination and other additive metal sources (like Fe, Co, Cu) were investigated in detail. We demonstrated that Ni−Mo alloying took place prior to MoCxformation during heating, which catalyzed the crystallization of MoCxat relatively low temperature. The MoCx/Ni-650 catalyst exhibited a quite low overpotential of 172 mV at 20 mA cm−2. The high performance originates from the synergistic effect between MoCxand Ni−Mo alloy, high ratio of Mo3+/Mo2+, as well as high electrochemically active surface area and low charge-transfer resistance. This work would open a new way to the design and fabrication of other transition-metal carbide catalysts. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim |
