Introduction to Outcome: Hydrogen has been considered as an efficient clean energy since it may be the alternatives to fossil fuels. Large-scale production and effective storage of hydrogen are the important research topics. In this field, the electrolysis of water is an environmentally friendly technique for hydrogen production. Recently, Prof. Yaqian Lan at Nanjing Normal University cooperating with Prof. Shuhong Yu at the University of Science and Technology of China have synthesizeda phosphorus doped porous carbon coated molybdenum dioxide-reduced graphene oxide hybrid material (denote as MoO2@PC-RGO), which is prepared by carbonizing polyoxometalate-based metal-organic frameworks/graphene oxide composite (POMOFs/GO) precursors at a relatively low temperature. POMOFs have the advantages of both MOFs and POMs, in which MOFs could provide regular carbon array derived from the ligands and POMs could function as the Mo and P source. In addition, the agglomeration of MoO2 can be avoided by confining the carbon skeleton, which is conducive to prepare the small-sized and uniform nanomaterials. Therefore, these nanoscale materials can improve the activities and stabilities of HER catalysts. The MoO2@PC-RGO nanocomposite displays an excellent HER activity in acidic solution approaching that of commercial 20% Pt/C. So far, it is one of the best high performance catalysts among the reported non-noble metal catalysts for the HER. This work provides a new idea to synthesize high performance catalysts and understand the relationship between construction and property.
The work was published in Angewandte Chemie Inernational Edition titled ‘Porous Molybdenum-Based Hybrid Catalysts for Highly Efficient Hydrogen Evolution’ (Angew. Chem. Int. Ed. 2015, 54, 12928-12932).It has been chosen as a Hot Paper and been reported in Chinese and English at the same time by MaterialsView website of Wiley.
