摘　　要：设计一种全光谱太阳能分级分质利用系统进行光热协同反应与集热一体化实验研究。该系统通过光热协同催化材料将太阳光中紫外及部分可见波段光的能量转化为化学能进行储存,并利用系统中的集热材料将太阳光中部分可见及红外波段的光能转化为热能进行储存,从而实现对全光谱太阳能的综合利用。实验以光热协同分解水制氢为目标反应,利用导热油进行集热。结果表明,在反应材料表面温度为414℃的条件下,氢气产量为15.65μmol/g,系统集热效率可达43.61%。A full spectrum solar energy classification and mass utilization system is designed to conduct the experimental study of photothermal 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%.
