Electrocatalytic water splitting driven by renewable electricity has been recognized as a promising approach for green hydrogen production. Different from conventional strategies in developing electrocatalysts the two half-reactions of (e.g., and oxygen evolution reactions, HER OER) separately, there growing interest designing bifunctional electrocatalysts, which are able to catalyze both OER. In addition, considering high overpotentials required OER while limited value produced oxygen, is another rapidly exploring alternative oxidation reactions replace hybrid toward energy-efficient generation. This Review begins with an introduction on fundamental aspects splitting, followed thorough discussion various physicochemical characterization techniques that frequently employed probing active sites, emphasis reconstruction during redox electrolysis. The design, synthesis, performance diverse based noble metals, nonprecious metal-free nanocarbons, overall acidic alkaline electrolytes, thoroughly summarized compared. Next, their application also presented, wherein anodic include sacrificing agents oxidation, pollutants oxidative degradation, organics upgrading. Finally, concise statement current challenges future opportunities presented hope guiding endeavors quest sustainable

Nanosized zero-valent iron (nZVI) is a promising persulfate (PS) activator, however, its structurally dense oxide shell seriously inhibited electrons transfer for O-O bond cleavage of PS. Herein, we introduced sulfidation and phosphorus-doped biochar breaking the pristine with formation FeS FePO 4 -containing mixed shell. In this case, faster diffusion rate atoms compared to components triggered multiple Kirkendall effects, causing inward fluxion vacancies further coalescing into radial nanocracks. Exemplified by trichloroethylene (TCE) removal, such unique “lemon-slice-like” nanocrack structure favored fast outward ferrous ions across PS activation high-efficient generation utilization reactive species, as evidenced effective dechlorination (90.6%) mineralization (85.4%) TCE. O 2 • - contributed most TCE decomposition, moreover, SnZVI@PBC gradually became electron-deficient thus extracted from achieving nonradical-based degradation. Compared nZVI/PS process, SnZVI@PBC/PS system could significantly reduce catalyst dosage (87.5%) amount (68.8%) achieve nearly complete degradation, was anti-interference, stable, pH-universal. This study advanced mechanistic understandings effects-triggered on nZVI corresponding rational design Fenton-like catalysts organics
