Abstract

A full spectrum solar energy classification and mass utilization system is designed to conduct the experimental study of photo-thermal coupling reaction and heat collection integration. The photo-thermal coupling catalytic materials is used in this system to convert the energy of ultraviolet and partial visible bands of sunlight into chemical energy for storage. And the heat-collecting materials is used to convert the light energy of partial visible and infrared bands of sunlight into thermal energy for storage. So that the comprehensive utilization of full spectrum solar energy is realized. In this paper, the objective reaction is to decompose water to produce hydrogen by photothermal coupling, and heat collection is carried out by using heat transfer oil. The results show that when the surface temperature of the reaction material is 414 ℃, the yield of hydrogen is 15.65 μmol/g, and the heat collection efficiency of the system is 43.61%.
