Using the method of direct glycosidation, this paper discusses the impact of raw material ratio, catalyst dosage and reaction temperature on the synthesis. It is concluded that the synthesis of APG-12 best reaction process condition is the molar ratio of alcohol and glucose 7:1;the reaction temperature is 115℃ and the amount of catalyst is 1.3%, controlling the reaction pressure in 3 - 4 kPa. The resulting products are analyzed by infrared spectroscopy.展开更多

The output current characteristic of the DSSCs is to explore factors that affect cell conversion efficiency and the effect of the mechanism. Experimental results show that the annealing temperature of 500°C and adding PEG of molecular weight 2000, the TiO2 thin film electrode TiO2 film electrode has good optical properties.展开更多
