Effect of operating variables on the preparation of NaTaO3 by spray pyrolysis and its performance for H2 evolution from water in a slurry reactor |
| 초록 |
NaTaO3 photocatalyst was prepared by spray pyrolysis process for water splitting under UV light. Precursor solution was prepared from NaNO3 and Ta(OC2H5)5 as precursors in nitric acid solution. Precursor preparation temperature, precursor concentration, Na/Ta ratio and doping concentration of La were controlled to screen photocatalysts with enhanced activity. In spray pyrolysis process, reaction temperature and residence time were controlled to find out optimum operating conditions for photocatalyst with high photocatalytic activity. Characteristics of NaTaO3 powder and its photocatalytic activity were also examined. |
