Small, Год журнала: 2023, Номер 19(42)

Опубликована: Июнь 15, 2023

Abstract Dual‐Active‐Sites Single‐Atom catalysts (DASs SACs) are not only the improvement of SACs but also expansion dual‐atom catalysts. The DASs contains dual active sites, one which is a single atomic site, and other site can be atom or type endowing with excellent catalytic performance wide range applications. categorized into seven types, including neighboring mono metallic SACs, bonded non‐bonded bridged asymmetric metal nonmetal combined space separated SACs. Based on above classification, general methods for preparation comprehensively described, especially their structural characteristics discussed in detail. Meanwhile, in‐depth assessments variety applications electrocatalysis, thermocatalysis photocatalysis provided, as well unique mechanism addressed. Moreover, prospects challenges related highlighted. authors believe great expectations this review will provide novel conceptual methodological perspectives exciting opportunities further development application

Direct seawater splitting for hydrogen production: Recent advances in materials synthesis and technological innovation

Green Energy & Environment, Год журнала: 2024, Номер unknown

Опубликована: Фев. 1, 2024

Direct seawater splitting has emerged as a popular and promising research direction for the synthesis of clean, green, non-polluting, sustainable hydrogen energy without depending on high-purity water in face world's shortage fossil energy. However, efficient is hindered by slow kinetics caused ultra-low conductivity presence bacteria, microorganisms, stray ions seawater. Additionally, producing an industrial scale challenging due to high production cost. To address these challenges, this review presents that from catalyst point view, designing catalysts with catalytic activity stability can directly affect rate effect splitting. From ion transfer perspective, membranes block harmful ions, improving mixed systems self-powered also provide new low-energy Finally, ideas directions further direct future are pointed out, aims achieving low-cost high-efficiency production.
