“…Aliwi and AL-Jubori (1989) 26 found that the formation of two main products from CO2 conversion including formic acid (HCOOH) and formaldehyde (HCOH) increased in the presence of H2S. 4 indicated that the oxidation energy of SO2 improved the CO2 reduction and led to the increase of SO 4 2− and CO /HCOOH formation, respectively.…”

“…This indicates that the presence of SO2 for CO2 reduction is better than H2O because it requires less energy. Therefore, the photogenerated holes and electrons would be instantaneously consumed and their separation was improved 4 . In the current study, the main product of SO2 removal by photocatalytic oxidation in the presence of humidity was sulfate (SO 4 2− ).…”

Single-step process for simultaneous removal of gaseous pollutants is more advantageous than multi-steps one. In this study, the efficiency of a novel synthetic zeolite (Ze) prepared from stone cutting sludge and a natural zeolite (clinoptilolite, Cp) as the supports of TiO2 photocatalyst were examined for the separate and simultaneous removal of SO2 and CO2 under solar irradiation using a parabolic trough collector (PTC). The composites exhibited a higher efficiency than raw zeolites and TiO2 for the removal of both gases. The maximum removal of SO2 by TiO2-Ze and TiO2-Cp under sunlight was 41.9 % and 56.2 % that enhanced to 53.4 % and 78.8 %, respectively in the presence of CO2. Correspondingly, it was 61.8 % and 68.7 % for single CO2 removal that increased to 74.2 % and 79.0 % in the binary gas stream. This behavior could be due to the enhanced simultaneous SO2 oxidation and CO2 reduction. The performance of coated composite for SO2 was higher than of powder one (54.3% vs. 41.9%) and for CO2 removal was almost close together (58.9% vs. 61.2%). This work promises the application of photocatalytic co-removal of SO2 and CO2 by using synthetic and natural zeolite under solar irradiation.

“…20 Among them, bismuth vanadate (BiVO 4 ), an n-type semiconductor, is regarded to be a photocatalyst that is full of potential due to its narrow band gap (2.4 eV), 21 together with its wide use in photoelectrocatalytic water splitting, 22 PEC sensors 23 and PEC CO 2 reduction. 24 However, it is not efficient in energy conversion due to the rate of rapid charge recombination. 25 The combination of other semiconductor elements and BiVO 4 will help to improve the electron transfer efficiency and facilitate electron-hole pair separation, thus enhancing the energy conversion efficiency.…”

Photovoltaic (PV)‐assisted photoelectrochemical (PEC) tandem cells with elevated hydrogen (H2) production rates are a practical approach for carbon‐dioxide‐free, green H2 production. A semitransparent single‐cell‐based wide‐bandgap perovskite solar cell (PSC) coupled with an Si photocathode provides sufficient potential for H2 generation when combined with a sulfate oxidation reaction. While energetically favorable ZnO as an electron transport layer (ETL) increases the V OC to 1.19 V for mixed‐halide perovskite, phase decomposition is induced when Br ions contacted the ZnO ETL. The SnO2 interlayer shows improved passivation, superior operational stability, and excellent performance among the various atomic layer deposited metal oxides tested. Furthermore, the resulting semitransparent PSC demonstrates reproducibility of its enhanced PV parameters (i.e., V OC 1.17 ± 0.01 V, FF = 76.78 ± 1.39%, and PCE = 11.95 ± 1.13%) due to better interface quality. The precise calculation of light absorption from both PV and Si for the overall tandem device leads to optimized light harvesting in the top and bottom electrodes, maximizing H2 production. Overall, the PV‐PEC device incorporated with a chemically stable semitransparent top PSC and bottom Si photocathode allows to accomplish stable H2 production at 11.1 mA cm−2 under unbiased conditions.
