Meanwhile the mechanism involved in the photocatalytic reduction
2.3. Preparation of Ag/AgCl-Bi2MoO6 composite sample
All deposited samples were synthesized through the deposition and Eeyarestatin I process. Briefly, Bi2MoO6 (0.32 g) were added to distilled water (60 ml) to get solution A, and the suspension was sonicated for 30 min. Then, 0.24 g of NaCl was added into solution A to form solution B. 0.0952 g AgNO3 (mass ratio of AgCl to AgCl/Bi2MoO6 was 20%) were added to 20 ml distilled water (named as solution C). Solution C was added drop-wise into solution B with vigorous stirring. The resulting suspension was stirred at room temperature for 30 min. All the above processes were performed in the dark. The products were filtered, washed with distilled water to remove residual ions (Na+ and Cl−).
The synthesis process of Ag/AgCl-Bi2MoO6 composite was described as follows: 0.3 g AgCl/Bi2MoO6 dispersed into 20 ml deionized water solution. Then, Ag nanoparticles were obtained on the energy flow surface of AgCl by photo-reduction technique. In the photo-reduction process, the suspension was illuminated by solar simulator 300 W Xe lamp (PLS-SXE300, Beijing Perfect Light Technology Co., Ltd.) for 30 min. All the samples were finally collected after centrifugation, washed with ethanol and deionized water; the final products were dried at 60 °C for 12 h and named as 20 wt% Ag/AgCl-Bi2MoO6 (B-4). Similarly, pure Bi2MoO6 (B-1), 2 wt% Ag/AgCl-Bi2MoO6 (B-2), 10 wt% Ag/AgCl-Bi2MoO6 (B-3), 30 wt% Ag/AgCl-Bi2MoO6 (B-5) and pure Ag/AgCl (A-1) samples were prepared.
