Abstract Anion exchange membrane (AEM) water electrolysis employing non-precious metal electrocatalysts is a promising strategy for achieving sustainable hydrogen production. However, it still suffers from many challenges, including sluggish alkaline evolution reaction (HER) kinetics, insufficient activity and limited lifetime of ampere-level-current-density HER. Here, we report an efficient HER at industrial-level current density wherein flexible WS 2 superstructure designed to serve as the cathode catalyst AEM electrolysis. The features bond-free van der Waals interaction among low Young’s modulus nanosheets ensure excellent mechanical flexibility, well stepped edge defect structure realize high catalytic favorable interface micro-environment. unique can effectively withstand impact high-density gas-liquid exchanges facilitate mass transfer, endowing long-term durability under industrial-scale density. An electrolyser containing this exhibits cell voltage 1.70 V deliver constant 1 A cm −2 over 1000 h with negligible decay rate 9.67 μV −1 .

Closing the carbon and nitrogen cycles by electrochemical methods using renewable energy to convert abundant or harmful feedstocks into high-value C- N-containing chemicals has potential transform global landscape. However, efficient conversion avenues have date been mostly realized for independent reduction of CO2 NO3–. The synthesis more complex C–N compounds still suffers from low efficiency due inability find effective catalysts. To this end, here we present amorphous bismuth–tin oxide nanosheets, which effectively reduce barrier catalytic reaction, facilitating highly selective urea production. With enhanced adsorption activation on catalyst, a coupling pathway based *CO2 rather than traditional *CO is realized. optimized orbital symmetry (*CO2) (*NO2) intermediates promotes significant increase in Faraday production an outstanding value 78.36% at −0.4 V vs RHE. In parallel, selectivity formation also 90.41% 95.39%, respectively. results insights provide valuable reference further development new catalysts CO2.
