“…Besides the existence of the strong interlayer bonding and weak interlayer, van der Waals interactions inside can lead to the outstanding photocatalytic activity and more special properties. [ 5,6 ] Among BiOX photocatalysts, BiOI with suitable band gap (approximately 1.8 eV) can be the most promising one because of the more efficient sunlight‐harvesting performance. [ 7,8 ] However, BiOI always exhibits poor photocatalytic performance because of the fast recombination of photogenerated electrons and holes derived from the narrow band gap.…”

Antibiotics, considered as persistent organic pollutants, have harmful effect on the environment and human health. We aimed at designing and fabricating ternary AgI/BiOI/UiO‐66 composites and evaluate the photocatalytic activities of tetracycline (TC) in water environment under visible light irradiation. X‐ray diffractometer (ХRD), scanning electron microscopy–energy dispersive X‐ray spectroscopy (SEM‐EDS), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET), and ultraviolet–visible (UV‐vis) diffuse reflectance spectra (DRS) analyses were carried out to characterize the ternary AgI/BiOI/UiO‐66 composites. The effects of pristine BiOI, UiO‐66, and AgI loading ratios on the AgI/BiOI/UiO‐66 composites for TC photodegradation were evaluated to obtain the optimal one (1‐ABU), which can remove 90.1% TC with visible light irradiation. In the batch experiment, the influences of pH, ion strength, TC concentration, and dosage of photocatalyst were investigated. 1‐ABU exhibited excellent photocatalytic activities and stability including pH and ion strength resistance in certain degree. After recycled five times, 1‐ABU still showed good degradation efficiency, indicating the advanced stability of the ternary composites. ·OH and h+ active species are the prime, whereas ·O2− act as secondary during the TC degradation process. 1‐ABU exhibits an n‐p‐n heterojunction, which can inhibit the recombination of photogenerated electron–hole pairs and generate more active ·OH species. This work highlights a reference for the design and synthesis of heterojunction for excellent photocatalytic performance.

“…iii. The occurrence of a chemical reaction between surface-adsorbed species and charge carriers initiates CO 2 reduction (Kumar et al, 2020a,b,c;Leitner, 1996;Raizada et al, 2020e;Sharma et al, 2020;Thakur et al, 2020). Lastly, successive reduction reaction requires adsorption of CO 2 molecule at the active sites of SC.…”

“…When the CO 2 molecule is adsorbed on the SC surface, it simultaneously acts as an electron acceptor or donor. Preferably, the redox potential of acceptor molecules must be more positive (lower in energy) than the conduction band (CB) edges of SC, and donor molecules should have redox potentials more negative (greater in energy) than the valence band (VB) of SC (Kumar et al, 2020a,b,c;Sharma et al, 2020).…”

The realization of artificial photosynthesis in the photocatalytic CO 2 transformation into valuable chemicals or solar fuels, such as CO, CH 4 , HCOOH, and CH 3 OH, by solar-light harvesting is a promising solution to both global-warming and energy-supply issues. Recently, zinc oxide (ZnO) has emerged as an excellent oxidative photocatalyst among non-titanium metal oxides due to its availability, outstanding semiconducting and optical properties, non-toxicity, affordability, and ease of synthesis. However, ZnO wide bandgap and inability to absorb in the visible region has demanded particular modification for its practical use as a sustainable photocatalyst. This review provides a panorama of the latest advancement on ZnO photocatalysis for CO 2 reduction with an overview of fundamental aspects. Various modification strategies such as transition metal and non-metal doping, loading of plasmonic metals, and surface vacancy engineering for tunning the properties and improving the performance of ZnO are elaborated. Composites or hetero-structuralization-based Z-scheme formation is also presented along with a detailed photocatalytic reduction mechanism. Moreover, a new novel Step-scheme (Sscheme) heterostructure modification with a charge transfer pathway mechanism is also highlighted. Finally, the key challenges and new directions in this field are proposed to provide a new vision for further improvement for ZnO-based photocatalytic CO 2 conversion.
