SnS2基异质结构:光催化和气体传感应用的研究进展
SnS2-based heterostructures:advances in photocatalytic and gas-sensing applications
摘要
Abstract
Recent advances in tin disulfide(SnS2)-based heterojunctions have demonstrated their great potential for photocatalysis and sensing applications,owing to their optimal bandgap(2.0-2.3 eV),remarkable stability,environmental compatibility,and outstanding surface reactivity.Despite these advantages,a comprehensive review systematically addressing this emerging field remains lacking.This review first outlines the state-of-the-art synthesis strategies for SnS2 heterostructures.It then critically evaluates their photocatalytic performance in key applications,including hydrogen evolution,environmental remediation,and hydrogen peroxide production.The gas-sensing capabilities are subsequently analyzed,with special emphasis on nitrogen dioxide and ammonia detection.Mechanistic studies reveal that the enhanced performance originates from tailored heterojunction designs:S-scheme configurations significantly boost charge separation in photocatalysis;n-n/p-n junctions optimize active site distribution and gas adsorption in sensing applications.The interfacial synergy between SnS2 and coupled semiconductors is identified as the key factor governing performance improvements.Finally,some conclusions and perspectives as well as future challenges are presented.关键词
