Simultaneous Photocatalytic Tetracycline Oxidation and Cr(VI) Reduction by Z-Scheme Multiple Layer TiO2/SnIn4S8

“…Therefore, 6-TS adopted the Zscheme heterojunction mode. 45 e − in the CB of TiO 2 and h + in the VB of SnIn 4 S 8 combined in an internal electric field. e − in the CB of SnIn 4 S 8 exhibited a more lower potential (−0.81 eV) compared to the redox potential of O 2 / • O 2 − (−0.33 eV), enabling them to effectively convert O 2 to • O 2 − .…”

“…20 Akin to the cascading biological oxic and anoxic treatment processes, 21,22 the photocatalytic oxic–anoxic relay process is expected to operate in a harmonious manner in which the organic substrates are transformed in the first step and become conducive for subsequent energy production purposes. 23…”

“…20 Akin to the cascading biological oxic and anoxic treatment processes, 21,22 the photocatalytic oxic-anoxic relay process is expected to operate in a harmonious manner in which the organic substrates are transformed in the first step and become conducive for subsequent energy production purposes. 23 In addition, it is urgent to exploit a bifunctional catalyst which can achieve efficient carbon conversion and water purification simultaneously. 24 Recently, covalent triazine framework (CTF) materials have attracted wide attention as visible-light response semiconductors due to their specific π-stacked structure which can offer certain sites for photoinduced charge transfer.…”

Improved CO2 Photoreduction Activity and Selectivity Using an Indirect Z-Scheme Heterojunction of ZIF-67 and Bi4O5Br2 Nanostructures

“…Metal–organic frameworks (MOFs) have gained significant attention due to their high surface area, tailored structures, and semiconductor-like behaviors, making them versatile for various applications, such as gas adsorption/separation, , recognition/sensing, , and catalysis. − In recent studies, MOFs have emerged as a promising platform for photocatalytic CO 2 reduction. ,− However, the activity and selectivity of individual MOF photocatalysts still suffer from problematic facets such as low light absorption efficiency, fast electron–hole recombination, and low activity of reaction sites. ,− To address these issues, the bulk-phase ion doping strategy has been proved effective in improving the performance of MOF photocatalysts. − For example, Wang group reported that a bimetallic strategy formed isostructural Co 1 Ni 2 -MOF can catalyze CO 2 reduction to CO, with the yield rate of 1160 μmol·g –1 ·h –1 and a selectivity of 94% . This case demonstrates that the bimetallic strategy is an effective means to optimize the catalytic performance of MOF catalysts for photochemical CO 2 reduction.…”
