Electrocatalytic and photocatalytic hydrogen evolution reaction (HER) via water-splitting are played a significant role in solving environmental energy crisis. Two-dimensional (2D) nanomaterials regarded as promising materials the electrocatalytic HER field due to its large surface area, good hydrophilicity brilliant electronic conductivity. However, several drawbacks, such low crystalline quality, productivity limited intrinsic active sites restrict industrial applications. Herein, facile green one-step method prepare Ni particles coated by carbon 2D nanosheet (2D Ni/C-m) through molten salt (NaCl)-facilitated pyrolysis is proposed. Benefit from excellent electrical conductivity, holey synergistic effect between composition structure of prepared Ni/C-m catalyst. The areas Ni/C-0.75 catalyst shows much better activities among samples. exhibits potential -110 mV -375 at -10 mA cm-2 -200 cm-2, which compare that Pt/C (η200 = -339 mV). also speed 78 umol h-1 with Eosin Y photosensitizer. Additionally, wonderful stability process electro/photocatalytic HER. These results provide new insight fabricate Ni-based catalysts for electro/photo-catalytic evolution.

Selective A‐Site Exsolution and Phase Transition in Perovskite Electrode for Efficient Flexible Znic‐Air Batteries

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Zinc-air batteries (ZABs) are highly promising for flexible electronics due to their high energy density and cost-effective. However, practical application is impeded by the sluggish kinetics of oxygen evolution reduction reactions (OER/ORR). This study presents a novel design featuring BaO nanoparticles anchored on layered perovskite PrBaMn1.5Co0.5O6-δ (PBMC) nanofibers, fabricated through plasma method. Notably, treatment induces selective exsolution A-site Ba onto surface, while simultaneously driving transformation PBMC from simple perovskite, resulting in unique BaO/PBMC heterostructure. Theoretical calculations demonstrate that construction heterojunction regulates interfacial electronic redistribution, thereby lowering barriers both OER ORR. Consequently, air electrode exhibits superior peak power enhanced stability solid-state ZABs, compared pristine cathode. Selective coupled with phase transition, alkaline-earth metal oxide/perovskite heterostructure, may offer new insights conversion technologies.

Abstract Electrocatalytic conversion of carbon dioxide (CO 2 ) into valuable carbon‐based fuels and chemicals represents a promising approach to closing the cycle setting circular economy. Nevertheless, for current electrocatalytic CO reduction reaction (ECO RR) systems, realizing 100% with simultaneously high overall rate (i.e., single‐pass conversion) Faradaic efficiency (FE) remains significant challenge. Enhancing often results in decrease FE, conversely, improving FE may limit rate. Metal–CO (M–CO batteries functions face similar challenges, particularly reversible M–CO batteries, which do not accomplish net because nearly all RR products are reoxidized during subsequent charging process. Such system neutrality poses substantial challenges. This perspective provides an in‐depth analysis state‐of‐the‐art ECO systems alongside main strategies employed address their respective The critical importance achieving both is underscored practical applications effectively close cycle. Furthermore, strategic roadmap that outlines future research directions presented, thereby facilitating advancement comprehensive electroconversion technologies.
