报告摘要：
Scalable and sustainable production of hydrogen through water electrolysis requires efficient electrode procedures for both hydrogen evolution (HER) and oxygen evolution reactions (OER). Theoretically, noble-metal free catalysts, such as carbon nanostructures and certain transition-metal-containing nanostructures can exhibit extremely high electrocatalytic activity for both HER and OER by rationally designing the electronic structures. Here, we show that nitrogen-doped graphene nanoribbons (N-GRWs) with interconnected three-dimensional network architectures exhibit superior OER and stability in alkaline solution, which are comparable to the state of the art of the noble metal electrocatalyst. To achieve efficient hydrogen production, a unique functional electrode made of hierarchal Ni-Mo-S nanosheets with abundant exposed edges anchored on conductive and flexible carbon fiber cloth has been developed through a facile biomolecule-assisted hydrothermal method. The incorporation of Ni atoms in Mo-S plays a crucial role in tuning its intrinsic catalytic property by creating substantial defect sites as well as modifying the morphology of Ni-Mo-S network at atomic scale, resulting in an impressive enhancement in the catalytic activity and stability. Our work demonstrates that efficient conversion of electricity to chemical energy can be achieved by rational design of the nanostructures.
