Abstract
With the increasingly severe energy crisis and environmental pollution, the application of nano-composite materials in the field of photoelectric chemical conversion has been widely concerned. In this paper, the characteristics, photoelectric chemical properties and optimization strategies of nanocomposites are systematically studied, and their prospects in the field of photoelectric conversion are prospected. In the section of properties of nanocomposites, the size effects and surface effects of nanocomposites, as well as the characteristics of heterogeneous interfaces of nanocomposites are analyzed in detail. These properties have important effects on the photoelectrochemical properties of nanocomposites. In the section of photoelectrochemical properties of nanocomposites, the mechanism of photoelectrochemical transformation, including light absorption and excitation, charge separation and transport, and interfacial reaction kinetics are discussed in detail. At the same time, the evaluation methods of photoelectrochemical performance are systematically introduced, including photocurrent-voltage characteristics, photoelectric conversion efficiency, stability and cycle life. In addition, the photochemical activity of nanocomposites in photocatalysis, photochemical sensing and photoelectrochemical cells has been studied. In the optimization strategy of nanocomposites, some strategies such as structure optimization, composition regulation, interface engineering and functional modification are proposed to improve the photoelectrochemical properties of nanocomposites. These strategies provide new ideas for the further research and application of nanocomposites. In the part of the prospect of photoelectric conversion of nanocomposites, this paper looks forward to its potential in new energy applications, environmental purification technology, theoretical limits and practical exploration of quantum efficiency, and the development of portable photoelectric devices. These application prospects point out the direction for the future development of nanocomposites. With the deepening of research, the application of nano-composite materials in new energy and environmental purification technology will show a broader prospect.
