Process of electrocatalytic synthesis of small molecule substances by porous framework materials
Small molecules,including inorganic compounds such as hydrogen,oxygen,ammonia,hydrocarbons,and hydrogen peroxide that can serve as energy sources,as well as organic compounds like urea and amino acids used in the biochemical industry,are assuming an increasingly pivotal role in daily life and production.The industrial syn-thesis of small molecule substances still faces challenges,such as the extensive utilization of precious metal cata-lysts and significant energy inefficiency.Electrochemical synthesis offers several advantages over traditional pro-cesses,including reduced catalyst costs,enhanced environmental sustainability,and superior performance.Porous material catalysts based on metal-organic frameworks(MOFs),covalent organic frameworks(COFs),and porous coor-dination cages(PCCs)have attracted extensive attention due to their unique morphology,adjustable structure,high catalytic activity,and excellent chemical stability.Therefore,a key area of future research on the electrocatalytic synthesis of small molecules lies in advancing porous framework materials as electrocatalysts for synthesizing small molecule substances.This review provides a comprehensive overview of the utilization of these materials in electro-catalysis.
