摘要
WO_(3)基光催化剂的研究在世界范围内受到了广泛的关注,尤其是在环境修复和能源生产领域。WO_(3)的禁带宽度为2.5~2.7 eV,在可见光范围内是制备各种光催化剂的潜在候选材料。作为地球上丰富的金属氧化物,WO_(3)显示出优异的光电特性及较高的稳定性。此外,它还具有无毒性、生物相容性、低成本、优异的空穴迁移率和可调的带隙等特点。综述了提高WO_(3)基纳米复合材料光催化性能的一些常见策略,如控制形貌、负载贵金属、构建异质结、形成碳基纳米复合材料等。此外,还总结了WO_(3)基纳米复合材料所面临的挑战和未来发展前景。
The development of WO_(3)-based photocatalysts has attracted much attention worldwide,especially in the fields of environmental remediation and energy production.WO_(3)has a band gap of 2.5~2.7 eV,within the visible light range,making it a potential candidate material for various photocatalytic processes.As an abundant metal oxide on Earth,WO_(3)shows excellent electronic and morphological properties,and high stability under extreme conditions.In addition,it has non-toxicity,biocompatibility,low cost,excellent hole mobility,and an adjustable band gap.In order to improve the photocatalytic performance of WO_(3)-based nanocomposites,this review summarizes some strategies for constructing ideal photocatalysts,such as controlling the morphology,loading precious metals,heterojunction formation,carbon-based nanocomposites,etc.In addition,the challenges and future development prospects of WO_(3)-based nanocomposites are summarized.
