Conventional metal oxide and its composites embrace the long-standing problem of using the combined visible and near-infrared (NIR) light. Doping with suitable impurities of metal, nonmetal, or its combinations for visible light enhancement is very well studied. However, the quantum efficiency of these photocatalysts does not produce an exciting appearance toward visible and NIR light when irradiated through either artificial or natural light. Furthermore, owing to the limited availability of solar light, challenges arise from the implication of these developed nano-photocatalysts. Therefore, the hybridized concept was developed for the effective use of either full or partial solar spectrum, even functioning in dark conditions. The present review focuses on the challenges of hybridized photocatalysts in storing and discharging the harvested photons obtained from the solar spectrum. The review vividly emphasizes the evolution of light-driven nanomaterials since its innovation and significant breakthroughs in brief, while a detailed presentation of the implications of hybrid photocatalysts for full solar applications, including the mechanistic features, charging-discharging characteristics, work function, charge carrier mobility, and interactions, follows. The article also delivers the substantial contribution of these materials in regard to energy and environmental application.

全太阳光谱驱动的光催化剂的挑战和意义

常规的金属氧化物及其复合材料包含使用组合的可见光和近红外(NIR)光的长期存在的问题。用金属,非金属或其组合物的合适杂质掺杂以提高可见光的能力得到了很好的研究。但是,当通过人造光或自然光照射时,这些光催化剂的量子效率不会对可见光和NIR光产生令人兴奋的外观。此外,由于太阳光的可用性有限,这些发达的纳米光催化剂的含意带来了挑战。因此,发展了杂交概念以有效利用全部或部分太阳光谱,甚至在黑暗条件下也能正常工作。本综述着眼于杂化光催化剂在存储和释放从太阳光谱获得的光子中所面临的挑战。这篇综述生动地强调了光驱动纳米材料自创新以来的发展和短暂的重大突破,同时详细介绍了混合光催化剂对完整太阳能应用的影响,包括机理特征,充放电特性,功函数,电荷载体随之而来的是移动性和互动性。本文还提供了这些材料在能源和环境应用方面的重大贡献。同时详细介绍了混合光催化剂对完整太阳能应用的影响,包括机械特性,充放电特性,功函数,载流子迁移率和相互作用。本文还提供了这些材料在能源和环境应用方面的重大贡献。同时详细介绍了混合光催化剂对完整太阳能应用的影响,包括机械特性,充放电特性,功函数,载流子迁移率和相互作用。本文还提供了这些材料在能源和环境应用方面的重大贡献。
