A range of different studies has been performed in order to design and develop photocatalysts that work efficiently under visible (and near-infrared) irradiation as well as to improve photons absorption with improved reactor design. While there is consensus on the importance of photocatalysis for environmental applications and the necessity to utilized solar irradiation (or visible-light) as driving force for these processes, it is not yet clear how to get there. Discussion on the future steps towards visible-light photocatalysis for environmental application is of great interest to scientific and industrial communities and the present paper reviews and discusses the two main approaches, band-gap engineering for efficient solar-activated catalysts and reactor designs for improved photons absorption. Common misconceptions and drawbacks of each technology are also examined together with insights for future progress.
已经进行了一系列不同的研究,旨在设计和开发在可见光(和近红外光)照射下有效工作的光催化剂,并通过改进反应器设计来提高光子吸收。虽然人们普遍认识到光催化在环境应用中的重要性,以及有必要利用太阳辐射(或可见光)作为这些过程的驱动力,但如何实现这一目标还不清楚。关于环境应用中可见光光催化的未来步骤的讨论引起了科学界和工业界的极大兴趣,本文综述并讨论了两种主要方法,即用于高效太阳能激活催化剂的能带工程和用于提高光子吸收的反应器设计。还一起检查了每种技术的常见误解和缺点,并为未来的进展提供了一些见解。
