Abstract

Overcoming low utilization of solar energy, enhancing light absorption, and exploring efficient photothermal materials are current research priorities. In this paper, Developing efficient photothermal materials with silicon lithium glass matrix, introducing gradient refractive index structure into carbon materials, and doping TiO2 to enhances light absorption. The resulting silicon lithium gradient refractive index TiO2/disordered mesoporous carbon exhibits superior photothermal properties, particularly under 980 nm laser, its temperature is significantly increased by 6.5 oC compared to undoped lithium silicon mesoporous carbon. The composite material has good photothermal properties, and has great development prospects in the photothermal field.
