摘　　要：光催化技术作为应对环境污染和能源短缺的先进解决方案,面临着太阳能转换效率低的挑战。WO_(3)是一种无毒、经济的n型半导体,因其适宜的禁带宽度而成为备受关注的光催化材料。尽管如此,光响应范围有限和高光生载流子复合率阻碍了其性能提升。综述了WO_(3)基光催化剂的制备及性能改性技术,如掺杂和构建异质结,旨在拓宽光吸收范围至可见光区,并提高了载流子分离与转移效率。还讨论了WO_(3)基光催化剂在光解水、有机污染物降解以及还原N_(2)和CO_(2)中的表现。最后展望了WO_(3)光催化剂的未来研究方向。Photocatalysis is a technology addressing environmental and energy challenges.But it is limited by low solar conversion efficiency.WO_(3),an eco-friendly and cost-effective n-type semiconductor,stands out in photocatalysis for its suitable band gap.Despite its potential,its narrow photo response and high carrier recombination rate limit its efficacy.Focusing on doping and heterojunction techniques to widen the light absorption spectrum to visible region and enhance carrier dynamics,the synthesis and modification technology for WO_(3)-based photocatalyst are summarized.The applications in photocatalytic water splitting,organic pollutant degradation,and N2and CO2reduction are discussed.Future research trajectories for WO_(3)photocatalysts are also proposed.
