Опубликована: Сен. 25, 2024

Abstract Designing efficient materials is crucial to meeting specific requirements in various electrochemical energy applications. Mono‐/bimetallic doped and heterostructure engineering have attracted considerable research interest due their unique functionalities potential for conversion storage. However, addressing material imperfections such as low conductivity poor active sites requires a strategic approach design. This review explores the latest advancements modified by mono‐/bimetallic heterojunction strategies It can be subdivided into three key points: (i) regulatory mechanisms of metal doping materials; (ii) preparation methods with strategies; (iii) synergistic effects two approaches, further highlighting applications supercapacitors, alkaline ion batteries, electrocatalysis. Finally, concludes perspectives recommendations advance these technologies.

Synergistic Enhancement of Oxygen Evolution by S-Ti₃C₂T_x MXene Folded Nanosheets Supported by Cobalt Hydroxide Nanoparticles

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(17), С. 20544 - 20552

Опубликована: Авг. 29, 2024

The metal active site-induced adsorbate evolution mechanism (AEM) and the lattice oxygen-mediated (LOM) can significantly improve performance of electrocatalytic oxygen reaction, but LOM is not easily triggered on AEM. Herein, a unique mixture transition Ti3C2Tx MXene cobalt hydroxide introduced. A sulfur-doped substrate with clear composition layered structure was formed thin-layer nanosheets by sulfur template method for study alkaline electrochemical evolution. Sufficient sites, robust structures, good kinetics, increased catalytic activity are provided resulting nanohybrids. Significantly, has more abundant vacancies better hydrophilicity; this interaction favorable improving reaction (OER). results tests support hypothesis that interfacial electron coupling two different components doping vacancy may optimize adsorption energy H2O *OH, leading to small overpotential 207 mV at 10 mA cm–2, material stable OER. This great potential development electrocatalysts where both AEM work together their applications in energy-related fields.

Опубликована: Дек. 11, 2024

Abstract Developing bifunctional electrocatalysts from earth‐abundant first‐row transition metals for large‐scale hydrogen production through water electrolysis is both promising and challenging. This study presents a ternary layered double hydroxide (LDH) as electrocatalyst the evolution reaction (HER) benzyl alcohol oxidation (BAOR). The synergy between 2D NiFeCo LDH non‐Ti‐based Nb 2 CT x MXene enhances electrochemical performance. achieves excellent results with low potential of 1.5 V versus RHE at 100 mA cm⁻ BAOR, an overpotential 320 mV 50 HER, stability over h. A solar cell‐powered HER||BAOR system shows faradaic efficiency ≈73.92% benzaldehyde solar‐to‐hydrogen (STH) ≈39.67%. In situ Raman analysis identifies oxyhydroxide group real catalytic active site during BAOR. These findings offer valuable insights linking fundamental research technological innovation to address global challenges.
