The novel three-component BiVO/BiS/MoS heterojunction was successfully fabricated through a facile in-situ hydrothermal method based on the formation of the intermediate BiS by coupling BiVO and MoS precursor. The BiS was easily formed attributing to the strong interaction between Biand S ions with the aid of the hydrothermal reaction. The photocatalytic performances of samples were systematically investigated via the photocatalytic degradation of Rhodamine B (RhB), methylene blue (MB) and malachite green (MG) under solar light irradiation. As a result, the photocatalytic degradation rate of BM-10 for RhB, MB and MG are 97%, 93% and 94%, respectively. The enhanced photocatalytic activities could be due to the suppression of charge recombination and the enhanced the visible light absorption of BiVO/BiS/MoS heterojunction.

An exceedingly porous and interwoven fibrous structure was achieved in this study by interlocking titanium carbide (TiC) MXenes onto the electrospun mats using poly(vinylidene fluoride) (PVDF) as the base polymer. The fibrous membrane was further modified with the inclusion of zinc oxide (ZnO) and tungstite (WO·HO) nano/microstructures via annealing and hydrothermal approaches. Through these strategic interfaced morphological developments in novel TiC/ZnO/WO·HO heterostructures, our findings reveal enhanced wettability and charge-segregation desirable for promoting oil-water separation and photoreactivity, respectively.

A variety of ZnCdS-based semiconductor nanoparticle heterostructures with extended exciton lifetimes were synthesized to enhance the efficacy of photocatalytic hydrogen production in water. Specifically, doped nanoparticles (NPs), as well as core/shell NPs with and without palladium and platinum co-catalysts, were solubilized into water using various methods to assess their efficacy for solar H fuel synthesis. The best results were obtained with low bandgap ZnCdS cores and ZnCdS/ZnS core/shell NPs with palladium co-catalysts.

Carbon catalysts have shown promise as an alternative to the currently available energy-intensive approaches for nitrogen fixation (NF) to urea, NH, or related nitrogenous compounds. The primary challenges for NF are the natural inertia of nitrogenous molecules and the competitive hydrogen evolution reaction (HER). Recently, carbon-based materials have made significant progress due to their tunable electronic structure and ease of defect formation.

Two porphyrin-based polymeric frameworks, SnP-BTC and SnP-BTB, as visible light photocatalysts for wastewater remediation were prepared by the solvothermal reaction of -dihydroxo-[5,15,10,20-tetrakis(phenyl)porphyrinato]tin(IV) (SnP) with 1,3,5-benzenetricarboxylic acid (HBTC) and 1,3,5-tris(4-carboxyphenyl)benzene (HBTB), respectively. The strong bond between the carboxylic acid group of HBTC and HBTB with the axial hydroxyl moiety of SnP leads to the formation of highly stable polymeric architectures. Incorporating the carboxylic acid group onto the surface of SnP changes the conformational frameworks as well as produces rigid structural transformation that includes permanent porosity, good thermodynamic stability, interesting morphology, and excellent photocatalytic degradation activity against AM dye and TC antibiotic under visible light irradiation.

This study is the first to convert two waste materials, waste rice noodles (WRN) and red mud (RM), into a low-cost, high-value magnetic photocatalytic composite. WRN was processed via a hydrothermal method to produce a solution containing carbon quantum dots (CQDs). Simultaneously, RM was dissolved in acid to form a Fe ion-rich solution, which was subsequently mixed with the CQDs solution and underwent hydrothermal treatment.
