Summary: In this study, MoS2/C-mica composites were prepared by introducing C-mica as a carrier, effectively suppressing the curvature and agglomeration of MoS2, thus enhancing the separation effect of photo-generated electron-hole pairs and photocatalytic ability. The resulting product exhibited outstanding visible photocatalytic activity and reusability for tetracycline hydrochloride, with a degradation rate of 90.6% after 60 minutes of irradiation. H(+) and center dot O(2-) radicals played important roles as the main active sites during the photocatalytic degradation process.

Summary: We have successfully synthesized ZnS-MoS2 nano-heterostructure via hydrothermal method and studied its photocatalytic activity under sunlight. The nano-heterostructure exhibited efficient charge separation and extended light absorption, leading to the generation of electron-hole pairs for the degradation of MB dye molecules. The optimized ZnS-MoS2 sample synthesized at 48 h showed excellent performance with 97% degradation in 30 min, attributed to enhanced crystallinity, good charge carrier ability, optimal heterojunction formation, and well-defined morphology with reduced defects.

Summary: In the process of photocatalysis, photon energy is converted into chemical energy using light and catalyst. This process has various applications such as degradation of hazardous compounds, nitrogen fixation, hydrogen production, air purification, water splitting, and carbon dioxide reduction. The study focuses on the synthesis of ZnO and MoS2/ZnO composites and their applications in photocatalytic degradation of ciprofloxacin antibiotic and hydrogen production. The MoS2/ZnO composites show superior photocatalytic activity compared to ZnO, attributed to extended light absorption capacity, effective charge transfer, suitable band alignment, and minimum recombination of charge carriers.

Summary: This paper presents the preparation and characterization of a visible light-driven polymeric carbon nitride (PCN)/(Pt)/nano-spherical MoS2 photocatalyst. The structure and energy band structure of the photocatalyst were investigated, and the photocatalytic performance was evaluated for the degradation of Rhodamine B and hydrogen evolution. The introduction of Pt nanoparticles greatly enhanced the photocatalytic activity, leading to higher degradation rate and increased hydrogen production rate compared to the PCN/2.0%MoS2 system.

Summary: This work successfully describes the S-scheme-based hydrothermal synthesis of SiO2@CuFe2O4-AgI composites. The nanocomposites with different weight percentages of AgI were tested for their photocatalytic activity in the visible range using methylene blue (MB) and methyl orange (MO) as target pollutants. SiO2@CuFe2O4-AgI with a 15% AgI loading showed superior photocatalytic performance, degrading both MB and MO significantly faster compared to pure and hybrid composites. The increased surface area, efficient separation of photogenerated carriers, and high redox capacity of SiO2@CuFe2O4-AgI (15%) contributed to its enhanced photocatalytic activity. The hybrid composite also exhibited excellent stability and reusability after 10 cycles. This research proposes a novel and cost-efficient approach for creating stable semiconductor-based photocatalytic systems and paves the way for future applications.
