Lead molybdate (PbMoO₄) materials were successfully synthesized using a facile surfactant-assisted microwave process and characterized by XRD, Raman, PL, BET and DRS. We also investigated the photocatalytic activity of these materials for the decomposition of Rhodamine B under UV-light irradiation. The XRD and Raman results revealed the successful synthesis of 42–69 nm, well-crystallized PbMoO₄ crystals with a facile surfactant-assisted microwave process. The PbMoO₄ catalysts prepared using microwave process enhanced the photocatalytic activity compared to PbMoO₄ catalyst prepared by hydrothermal method. The PbMoO₄ catalyst prepared at 100 °C showed the highest photocatalytic activity. The PL peak was appeared at about 540 nm for all catalysts and the excitonic PL signal was proportional to the photocatalytic activity for the decomposition of Rhodamine B.

In this study, the NiFe-LDH doped with different Pt group metals (Pt, Ru, Ir, Rh) was prepared as a cocatalyst for photocatalytic H production over g-CN. It is found that the doped NiFe-LDH loaded g-CN generally displays higher photocatalytic activity than the raw NiFe-LDH modified one, where the NiFeRu-LDH loaded g-CN shows the optimal H evolution rate of 77.4 μmol h, about 5.

The H-evolution kinetics play a pivotal role in governing the photocatalytic hydrogen-evolution process. However, achieving precise regulation of the H-adsorption and H-desorption equilibrium (H/H) still remains a great challenge. Herein, we propose a fine-tuning d-p hybridization strategy to precisely optimize the H/H kinetics in a Ni-B modified CdS photocatalyst (Ni-B/CdS).

Metal-organic frameworks (MOFs) have shown significant potential in the photocatalytic activation of peroxydisulfate (PDS). Although many MOFs have been investigated for their ability to activate PDS, the impact of structural interpenetration on this process remains underexplored. In this study, MIL-88D(FeNi) and MIL-126(FeNi) were selected to systematically study this effect.

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.

This study investigates the synthesis, characterization, and functional properties of well-aligned zinc oxide (ZnO) nanowires (NWs) obtained by a two-step hydrothermal method. ZnO NWs were grown on silicon substrates precoated with a ZnO seed layer. The growth process was conducted at 90 °C for different durations (2, 3, and 4 h) to examine the time-dependent evolution of the nanowire properties.
