Room-temperature sodium–sulfur (RT-Na/S) batteries possess high potential for grid-scale stationary energy storage due to their low cost and high energy density. However, the issues arising from the low S mass loading and poor cycling stability caused by the shuttle effect of polysulfides seriously limit their operating capacity and cycling capability. Herein, sulfur-doped graphene frameworks supporting atomically dispersed 2H-MoS2 and Mo1 (S@MoS2-Mo1/SGF) with a record high sulfur mass loadin...

Designing atomically dispersed non-precious metal catalysts for 2e− oxygen reduction reaction (ORR) is an appealing strategy to harness O2-to-H2O2 chemistry. Nevertheless, prevailing M–N–C single-atom catalysts (SACs) might still not satisfy the directional regulation of ORR selectivity, hence fail to uphold scalable H2O2 electrosynthesis with a high yield. Herein, we report the precise synthesis of (O,N)-coordinated Fe SAC (FeN2O2) and relating investigation of its performance in H2O2 pro...

Downsizing and atomically dispersing metal species particles on a carrier substrate has emerged as a new frontier of heterogenous catalysis, which can achieve maximize the utilization efficiency of metal element, in structures such as single atom catalysts (SACs), dimer, cluster and nanoparticle catalysts. Moreover,benefitting from the optimized geometric and electronic structure, the adsorption and desorption ability for different reaction intermediates can be optimized. Over the past decades, ...

Hydrogen peroxide (H2O2) is a valuable chemical for a wide variety of applications. The environmentally friendly production route of the electrochemical reduction of O2 to H2O2 has become an attractive alternative to the traditional anthraquinone process. The efficiency of electrosynthesis process depends considerably on the availability of cost-effective catalysts with high selectivity, activity, and stability. Currently, there are many outstanding issues in the preparation of highly selective ...
