Abstract
Cu(NO3)2·3H2O and Ce(NO3)3·6H2O were used as modifier to make Cu-Ce/TiO2 by sol-gel method. The influences of Cu-Ce loading capacity, Cu and Ce molar ratio, sintering temperature on Cu-Ce/TiO2 performance were explored. Then, surface morphology, particle size distribution, pore structure and optical property of Cu-Ce/TiO2 were characterized by SEM,LPSA,BET and UV-Vis, respectively. The results show that:prepared Cu-Ce/TiO2 shows good photocatalytic-moisture performance when Cu-Ce loading capacity is 3%, Cu and Ce molar ratio is 1:1 and sintering temperature is at 500℃. Cu-Ce/TiO2 presents approximate sphere, with better uniformity and dispersibility and the particle size distribution is 1202.98-5364.48nm, with d50 2437.57nm. Cu-Ce/TiO2 has pore structure, approximate to an "ink bottle" with a narrow bottleneck, with the specific surface area 105.55m2/g, hole size 0.1200-0.1246mL/g, and average pore diameter 3.44-4.02nm. Cu-Ce doping promotes to form a new energy level inside Cu-Ce/fiO2 so as to improve the ability to capture e- and h+, enhance the efficiency of photon utilization, and promote red shift of absorption sideband.
