Abstract Electrocatalytic CO 2 reduction technology offers an effective way to convert into valuable chemicals and fuels, presenting a sustainable solution for carbon emissions. Current electrocatalytic technologies encounter significant issues such as salt precipitation hydrogen evolution, which prevent energy conversion efficiency, selectivity, current density, stability from simultaneously meeting industrial standards. In recent years, researchers have discovered that increasing the pressure on gas supply could enhance coverage of catalyst activate more reaction sites surface, provides practical approach optimizing mass transfer. this review, we provide comprehensive review development history status high-pressure technology, focusing its devices, catalytic performance, mechanisms. Furthermore, summarize offer insights most promising research avenues propel field forward.
