Near-infrared photocatalysis based on upconversion nanomaterials

【摘要】 As the global energy crisis and environmental pollution problems become increasingly severe, it is important to develop new energy capture and pollution management methods. Among these new technologies, photocatalysis has garnered significant interest because of its significant application prospects in harnessing pollution-free solar energy to degrade organic pollutants. From a fundamental scientific and technical perspective, improved optical frequency is a key research topic that provides a useful framework for studying the optical processes impacted by the local photonic environment.This type of study is especially pertinent because plasmonics emphasizes nonlinearity. Thus, near-infrared(NIR) catalysis has received considerable attention. In this review, we aimed to provide an integrated framework for NIR photocatalysis.We briefly introduce photocatalysis based on upconversion(UC) materials, including the efficiency of UC materials and the bination and energy transfer process between the semiconductor and UC particles as well as photoelectric response photocontrolled-delivery and photodynamic therapy based on NIR-responsive materials.更多还原
