Crystallization mechanism and photocatalytic performance of vanadium-modified bismuth oxide through precipitation processes at room temperature. Issue 36 (16th August 2016) - Wu, Yu-Chun
Abstract : Well-crystallized bismuth oxides (Bi2 O3 ) were synthesized through precipitation processes operating at room temperature. Abstract : Well-crystallized bismuth oxides (Bi2 O3 ) were synthesized through precipitation processes operating at room temperature. Two synthesis routes were used, which led to Bi2 O3 products with completely different phase structures. The crystallization mechanisms of γ-Bi2 O3 and δ-Bi2 O3 in relation to the synthetic processes were discussed. The role of vanadium (V) ions and the doping limit on the structural modification were also investigated. The photocatalytic efficiencies of the V-modified γ-Bi2 O3 and δ-Bi2 O3 compared with TiO2 P25 powder were discussed.
