“…The selectivity of CO production over TiO 2 and N/TiO 2 were much closer (96 %) but increased to 99 % in Cu/TiO 2 catalyst. However, the production of CO as the main product over Cu/TiO 2 and N/TiO 2 was due to thermodynamic reduction potential difference between TiO 2 (-0.5 eV) and CO 2 /CO (-0.48 eV) [2].…”

“…Numerous efforts are devoted to CO 2 capture, storage and utilization; yet photocatalytic CO 2 transformation to fuels provides one prospective path for the storage of solar energy to chemical energy [2,3]. During the recent decades, photocatalytic CO 2 reduction to carbon monoxide [4], methane [3], methanol [5] and hydrocarbons [6] over different types of semiconductor materials has been consistently drawing increasing attention.…”

“…For example, Wang et al reported a methane production of 0.09 µmol g −1 h −1 using TiO 2 doped with cobalt [52]. When the TiO 2 was doped with an amine, the yield was 0.15 µmol g −1 h −1 [53]. Metal deposition has also been used to improve photocatalytic performance of TiO 2 photocatalytic performance, thus Pt has been reported to enhance (1300 µmol g −1 h −1 ) the methane production compared to pure TiO 2 (0.8 µmol g −1 h −1 ) [54].…”

The reduction of CO2 is relevant for the production of compounds as part of the carbon capture and utilization research approaches. Thus, photocatalytic reduction of CO2 over a tailored BiOCl-based photocatalyst (BTEG) was tested under UV light (365 nm). BTEG was synthesized in the presence of triethylene glycol, which gave 4-nm crystallites, much smaller than the 30 nm crystallites of commercial BiOCl. Commercial BiOCl reduced CO2 mainly to methane with a minor fraction of ethanol, and was inactivated after 20 h. BTEG was a more active catalyst for CO2 photoreduction, producing approximately equal amounts of methane, methanol, and ethanol while consuming 0.38 µmol g−1 h−1 of CO2 before the experiment was stopped after 43 h, with the catalyst still active. The different products formed by the BTEG photocatalyst samples were tentatively ascribed to its greater content of {110} facets. Thus, in addition to band-gap tuning, the relative fractions of BiOCl facets had a key role in the effective photocatalytic reduction of CO2, and the BiOCl-based BTEG catalyst promoted the formation of important compounds as methanol and ethanol.

“…Therefore, the development of novel visible-light-driven photocatalysts is required for the purpose of taking full use of solar energy and improving quantum efficiency. In order 2 of 12 to achieve the goal, much research has been devoted to the modification of traditional TiO 2 [3][4][5][6][7] and the pursuit of other materials such as bismuth sulfide (Bi 2 S 3 ) [8][9][10].…”

3D hierarchical Bi 2 S 3 architectures have been successfully synthesized via a simple and effective hydrothermal process. The as-prepared Bi 2 S 3 samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen adsorption-desorption isotherms, and UV-vis diffuse reflectance spectrum (DRS). The observation of field emission scanning electron microscope (FESEM) images showed that numerous nanoplatelets are randomly arranged and interconnected with each other, which are assembled into 3D hierarchical Bi 2 S 3 architectures. The photocatalytic activity of the as-prepared Bi 2 S 3 samples was evaluated by the degradation of Rhodamine B (RhB) under visible light irradiation. The effect of hydrothermal temperature, reaction time, pH value and shape on the photocatalytic efficiency of the as-prepared Bi 2 S 3 samples was investigated. The results showed that 3D hierarchical Bi 2 S 3 architectures prepared at 165 • C for 12 h at a pH of 2.4 exhibits high photocatalytic efficiency, which could be ascribed to the synergetic effect of the shape, surface area, crystallinity, band gap and crystalline size.
