Abstract Constructing built‐in electric field (BIEF) in heterojunction catalyst is an effective way to optimize adsorption/desorption of reaction intermediates, while its precise tailor achieve efficient bifunctional electrocatalysis remains great challenge. Herein, the hollow Mo/MoS Vn nanoreactors with tunable BIEFs are elaborately prepared simultaneously promote hydrogen evolution (HER) and urea oxidation (UOR) for sustainable production. The BIEF induced by sulfur vacancies can be modulated from 0.79 0.57 0.42 mV nm −1 , exhibits a parabola‐shaped relationship HER UOR activities, V1 nanoreactor moderate presents best activity. Theoretical calculations reveal that evidently facilitate breakage N─H bond UOR. electrolyzer assembled delivers cell voltage 1.49 V at 100 mA cm −2 which 437 lower than traditional water electrolysis, also excellent durability 200 h. Life cycle assessment indicates HER||UOR system possesses notable superiority across various environment impact energy consumption. This work provide theoretical experimental direction on rational design advanced materials energy‐saving eco‐friendly

Abstract The rechargeable Zn‐redox battery represents a promising, efficient, and sustainable energy storage technology. Herein, novel 4‐nitrobenzyl alcohol (4‐NBA)‐assisted battery, driven by NiSe─Cu 2 Se/NF bifunctional electrocatalysts is developed. different redox activities of ─NO ─OH groups in 4‐NBA allow conversion for chemical production during the whole discharge/charge process, maximizing economic value technologies. Detailed charge analyses indicate that internal electric field within Se heterostructure modulates d‐band center, optimizes adsorption/desorption strength intermediates, reduces reaction barriers 4‐NBA. This electrocatalyst enables selective to 4‐aminobenzyl discharge process 4‐nitrobenzoic acid with Faradaic efficiencies above 96%. Consequently, 4‐NBA‐assisted achieves high power density 16.13 mW cm −2 maintains stable yield rate 15.92 µmol h −1 22.84 acid. work presents an appealing strategy integrating the‐whole‐process production, paving way developing multifunctional systems.

Abstract Engineering nanomaterials at single-atomic sites could enable unprecedented catalytic properties for broad applications, yet it remains challenging to do so on the surface of multimetallic nanocrystals. Herein, we present multifactorial engineering (size, shape, phase, and composition) fully ordered PtBi nanoplates atomic level, achieving a unique catalyst where face-centered cubic ( fcc ) Pt edges are modified by isolated Pd atoms BiO x adatoms. This 1 /Pt-BiO electrocatalyst exhibits an ultrahigh mass activity 16.01 A mg −1 Pt+Pd toward ethanol oxidation in alkaline electrolyte enables direct fuel cell peak power density 56.7 mW cm −2 . The surrounding adatoms critical mitigating CO-poisoning surface, /Pt single-atom alloy further facilitates electrooxidation CH 3 2 OH. work offers new insights into rational design construction sophisticated highly efficient electrocatalysis.

Abstract Methanol electrolysis, coupling thermodynamically favorable methanol oxidation reaction (MOR) and hydrogen evolution (HER), is a promising strategy for energy‐saving generation as compared with traditional water splitting. Pt‐based catalysts are the best choice while intrinsic activity utilization of Pt should be increased due to its high cost. Supporting engineering effective in boosting catalytic effectiveness, some novel supports diverse support effects developed accelerate kinetics improve efficiency. Herein, comprehensive review recent advances electrocatalysts methanol‐assisted production provided. The mechanism electrolysis anode MOR cathode HER first outlined, respectively. Then, performance enhancement effects, including anchoring, electronic, synergistic, strain briefly discussed. Subsequently, clarified by supports, metal oxides, phosphides, selenides, tellurides, presented, promotion effect relevant challenges future perspectives concluded last section, where most attention paid metal‐supporting their understanding study.
