The realization of low-cost hydrogen economy electrochemically hinges on substantial improvements in new materials that effectively catalyze four fundamental reactions, i.e., oxygen evolution reaction (OER), hydrogen evolution reaction (HER), oxygen reduction reaction (ORR), and hydrogen oxidation reaction (HOR). Idea electrocatalysts must be highly active, stable and geologically abundant. Although recent advances in the development of heterogeneous catalysts to negotiate the above reactions, substantial progresses are still impeded by the lack of inexpensive catalytic materials that enable high current densities at low overpotentials over prolonged time periods. Over the past years, we have been paying intensive attention on transition metal chalcogenide structures for designing electrocatalysts. In this talk, we will report on our recent efforts on the synthesis of transition metal chalcogenide nanostructures, as well as grafting related hybrid materials for advanced electrolysis. Systematic studies demonstrated that the electrocatalytic performances of these transition metal chalcogenide hybrids can be much improved because of their modified electrocatalytic interface, engineered electronic structure, and/or the combined catalytic proficiencies. The promising applications of transition metal chalcogenides for several important electrochemical reactions, such as OER, HER, and methanol-tolerant ORR will be highlighted.
