BiMoO was one of the important bismuth-based semiconductors with a narrow bandgap, and has been widely used in selective oxidation catalysts, supercapacitors, and energy-storage devices. A series of BiMoO/ZnO composite photocatalysts with different mass ratios were synthesized by the hydrothermal method. The synthesized samples were characterized by XRD, PL, UV-Vis, SEM, TEM, XPS, and BET analysis techniques. Under visible light conditions, Methylene blue (MB) was used as the target degradation product to evaluate its photocatalytic performance. The results showed that the degradation rate constant of BiMoO/ZnO (0.4-BZO) was about twice that of the traditional photocatalysis of ZnO. The BiMoO/ZnO composite catalyst maintained stable performance after four consecutive runs. The high photocatalytic activity of BiMoO/ZnO was attributed to the efficient electron transport of the heterojunction, which accelerates the separation of electron-hole pairs and reduces the probability of carrier recombination near the BiMoO/ZnO heterojunction. BiMoO/ZnO nanocomposites have potential applications in the field of photodegradation.

Constructing heterojunctions between phase interfaces represents a crucial strategy for achieving excellent photocatalytic performance, but the absence of sufficient interface driving force and limited charge transfer pathway leads to unsatisfactory charge separation processes. Herein, a doping-engineering strategy is introduced to construct a In─N bond-bridged InS nanocluster modified S doped carbon nitride (CN) nanosheets Z-Scheme van der Waals (VDW) heterojunctions (InS/CNS) photocatalyst, and the preparation process just by one-step pyrolysis using the pre-coordination confinement method. Specifically, S atoms doping enhances the bond strength of In─N and forms high-quality interfacial In─N linkage which serves as the atomic-level interfacial "highway" for improving the interfacial electrons migration, decreasing the charge recombination probability.

Efficient separation of photogenerated charge carriers is essential for maximizing the photocatalytic efficiency of semiconductor materials in oxygen evolution reactions (OER). This study presents a novel trimetallic photocatalyst, MIL-100(Fe)/TiO/CoO, synthesized through a facile microwave-assisted hydrothermal method followed by atomic layer deposition (ALD). The porous MIL-100(Fe) serves as a support for the sequential deposition of TiO and CoO layers ALD, which enhances electron-hole pair separation and minimizes their recombination.

A significant enhancement in the photocatalytic activity of metal-organic frameworks (MOFs) is achieved by expanding the visible-light response range through the strategic incorporation of functional groups, such as metalloporphyrins. Herein, Pd-metalised tetrakis(4-carboxyphenyl)porphyrin (PdTCPP) photosensitiser is integrated into the UiO-66-(NH) framework, creating the hybrid material PdTCPP ⊂ UiO-66-(NH) using a facile mixed-ligand strategy. Platinum nanoparticles (Pt NPs) are subsequently introduced as a co-catalyst via in situ photoreduction, resulting in the formation of the Pt/PdTCPP ⊂ UiO-66-(NH) hybrid material, which demonstrates exceptional catalytic performance under visible-light irradiation.

The chemical structure and photoredox properties of carbon dots () are not yet fully understood. However, it has been reported that, by carefully choosing the starting materials and tuning their synthesis conditions, it is possible to obtain with different chemical structures and therefore different photocatalytic performance. For this work, a family of different was synthesized in Milli-Q water a microwave-assisted protocol, using citric acid and urea as precursors.
