Electrocatalysis underpins the renewable electrochemical conversions for sustainability, which further replies on metallic nanocrystals as vital electrocatalysts. Intermetallic have been known to show distinct properties compared their disordered counterparts, and long explored functional improvements. Tremendous progresses made in past few years, with notable trend of more precise engineering down an atomic level investigation transferring into practical membrane electrode assembly (MEA), motivates this timely review. After addressing basic thermodynamic kinetic fundamentals, we discuss classic latest synthetic strategies that enable not only formation intermetallic phase but also rational control other catalysis-determinant structural parameters, such size morphology. We demonstrate emerging nanomaterials potentially advancement energy electrocatalysis. Then, state-of-the-art characterizations representative electrocatalysts emphasis oxygen reduction reaction evaluated a MEA setup. summarize review by laying out existing challenges offering perspective future research directions toward practicing conversions.

On-site H2O2 electrosynthesis via two-electron oxygen reduction reaction (ORR) is attracting great interest for water treatment. The use of carbon black-based gas-diffusion electrodes (GDEs) especially appealing, but their activity, selectivity and long-term stability must be improved. Here, a facile GDEs modification strategy using trace polymethylhydrosiloxane (PMHS) allowed outstanding production, outperforming the conventional polytetrafluoroethylene (PTFE)-GDE (1874.8 vs 1087.4 mg L-1 at 360 min). superhydrophobicity conferred by PMHS endowed catalytic layer with high faradaic efficiencies (76.2%-89.7%) during operation 60 h. electrochemical tests confirmed activity PMHS-modified GDE. Moreover, efficient degradation several micropollutants electro-Fenton process demonstrated potential new An in-depth understanding roles functional groups provided from DFT calculations: −CH3 contribute to form superhydrophobic interface, whereas Si-H as-formed Si-O-C sites modulate coordination environment active centers.
