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, numerous atomic-level electrocatalysts have been designed and successfully applied in the field of e...

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 catalysts, the exploration of the interface electrolysis environment, and the construction of electr...
