| 英文摘要: | To explore the possibilities of bismuth molybdate in CO 2 photo-reduction to chemicals and fuels, two types of bismuth molybdate namely Bi 2 MoO 6 and Bi 3.64 Mo 0.36 O 6.55 were synthesized via hydrothermal treatment by adjusting the pH of reaction solution. Bi 2 MoO 6 is constituted by MoO 6 octahedra while Bi 3.64 Mo 0.36 O 6.55 is constructed by MoO 4 tetrahedra. Different structure causes quite different properties, like electron binding energy, photoluminescence character, band edge position, optical and electrochemical properties. Comprehensively speaking, Bi 2 MoO 6 made the most of solar energy and showed relatively more efficient charge migration and separation efficiency, contributing to its higher activity for CO 2 photo-reduction. After irradiating for 5 h, the yields of CO gas over the both samples were 85.5172 (Bi 2 MoO 6 ) and 57.3259 (Bi 3.64 Mo 0.36 O 6.55 ) μmol/g, respectively. Last, the photocatalytic reduction mechanism was analyzed. © 2018 Elsevier Ltd. |
