The effects of nano-TiO2 dosage, Ca/S and temperature on CaO desulfurization and coal combustion were studied. The products were characterized by SEM and IR analysis. The catalysis mechanisms of nano-TiO2 were discussed. The results show that desulfurization efficiency was 87.7% when nano-TiO2 dosage is 6%, Ca/S 2, temperature 850degC; it was 16.8% higher than that without addition. The ignition temperature,...

Fuel cells will be applied extensively in the future as renewable energy sources, explaining why a considerable amount of research has addressed this topic. However, among the various problems encountered in the mass production of fuel cells that have yet to be solved include those associated with the bipolar plate, flow channel, catalyst, membrane electrode assembly (MEA), gas diffusion layer (GDL)...
Transition metal ion (V, Fe, or Cu) doped TiO2 nanoparticles were synthesized from titanium tetraisopropoxide (TTIP) in absolute ethanol by the modified sol-gel method. The precursor of the transition metal to be doped was added to an alcoholic solution containing TTIP. This solution was loaded into a pouch type cellophane membrane and placed in a clear solution containing 1:1 (v/v) ratio of absolute...
