英文摘要: Semimetal bismuth has attracted extensive interests, which were ascribed to the photo-thermal effect and co-catalyst properties. In this paper, Bi/Bi4O5I2 composites were synthesized through a molecular precursor hydrolytic process, and the sunlight induced semimetal Bi mediated photo-thermocatalysis of Bi4O5I2 for carbon dioxide to chemical energy was studied. When the optimal mole ratio of Bi: I was selected at 1.95:1, Bi/Bi4O5I2 displayed outstanding photo-thermocatalytic carbon dioxide to chemical energy (CO and CH4). Under simulate sunlight (UV–vis-IR) irradiation, the CO and CH4 generation over Bi/Bi4O5I2 enhanced to 40.02 μmol h−1 g−1, and 7.19 μmol h−1 g−1, respectively. The light to chemical energy (LTCE) conversion efficiency (80.2 × 10−6) was about 6.47 times than Bi4O5I2 (12.4 × 10−6), and 68.55 times than Bi4O5I2 without IR irradiation (1.17 × 10−6). The dramatically enhanced photo-thermocatalysis activity of Bi/Bi4O5I2 can be attributed to the co-catalyst and photo-thermal effect of Bi nanoparticles, which prohibiting the electron–hole recombination and accelerating light to thermal energy conversion, respectively. Furthermore, the enhanced photo-induced carrier separation rate and reaction system temperature of Bi/Bi4O5I2 was testified. © 2017 Elsevier Ltd
