Summary: This study presents the synthesis of SiO2/Nb2O5 and SiO2/ZnS heterostructures using the microwave-assisted hydrothermal (MAH) method, which is fast and low temperature. The obtained silica was found to be amorphous, and SEM images showed that Nb2O5 and ZnS interacted with the SiO2 surface, filling the voids. The heterostructures showed enhanced decolorization efficiency for dyes such as rhodamine B (RhB) and methylene blue (MB), demonstrating the potential of utilizing rice husk residue for improving photocatalytic activity.

Summary: This study develops a multidimensional In2O3/In2S3 (IO/IS) heterojunction with abundant lattice distortion structure and high concentration of oxygen defects to improve the performance of photocatalytic CO2 reduction. The heterojunction with close contact interfaces facilitates electron transmission and enhances the adsorption and activation of CO2 on the catalyst surface. The perfect combination of band matching oxide and sulfide effectively reduces the energy barrier of the CO2 reduction reaction. Furthermore, the lattice distortion structure provides additional active sites and optimizes the reaction kinetics. The optimal IO/IS heterojunction demonstrates superior CO2 reduction performance. This work emphasizes the importance of tight interfaces in heterojunction for improving CO2 photoreduction performance and provides an effective strategy for constructing heterojunction photocatalysts.

Summary: The interest in noble-metal-free semiconductor photocatalysts for efficient H2 production under simulated sunlight is high among researchers. In this study, a novel ZnO@ZnS core-shell nanorod with varying ZnO core thicknesses was synthesized through partial vulcanization. The ZnO@ZnS (1:1) material exhibited the best photocatalytic performances, with hydrogen production rates significantly higher than other materials tested. The improved performance can be attributed to the distinctive internal structure of ZnO core and the homologous heterogeneous interface between ZnS and ZnO.

Summary: High-chromium vanadium slag (HCVS) is an important by-product in the smelting process of high-chromium-vanadium-titanium-magnetite. In this study, direct acid leaching and calcium-roasting acid leaching were used to recover vanadium and chromium from HCVS. The experimental parameters, including H2SO4 concentration, reaction temperature, reaction time, and liquid-to-solid ratio, were investigated. The results showed that only a small percentage of chromium could be leached out, while calcium-roasting technology significantly increased the leaching efficiency of vanadium.

Summary: BiOCl0.5X0.5 (X = F, Br, and I) heterojunctions were prepared for the solar-light induced photodegradation of tetracycline hydrochloride (TCH). Among the samples, BiOCl0.5I0.5 exhibited the best photocatalytic activity. The Z-scheme junction between BiOCl and BiOI facilitated the efficient separation and migration of photo-generated charge carriers, and the narrow band-gap structure of BiOCl0.5I0.5 microspheres favored visible-light harvesting. The solar-light deactivation of BiOCl0.5I0.5 was attributed to the change in valence states induced by photo-corrosion.

Summary: Using various analysis techniques, the study investigates the degradation process of magnesium oxychloride cement (MOC) in outdoor dry-wet environments. As the number of dry-wet cycles increases, water molecules gradually penetrate the MOC samples, leading to the hydrolysis of P5 and hydration reactions of unreacted active MgO. This results in the appearance of cracks on the surface and warped deformations. The microstructure of the MOC samples changes from a gel state to a flake shape, with a loose structure. The compressive and flexural strength of the samples decrease significantly after multiple cycles.

Summary: Polypyrrole-decorated Mg-Al layered double oxides (PPy/Mg-Al) were prepared for enhanced adsorption capacity of Rhodamine B. PPy/Mg-Al composites showed better adsorption capacity compared to Mg-Al layered double oxides, with an optimum 2-PPy/Mg-Al achieving a Langmuir adsorption capacity of 200.10 mg g-1. The adsorption capacity decreased after seven cycles due to changes in surface compositions and discharge nature. The adsorption process of 2-PPy/Mg-Al for RhB removal was spontaneous and endothermic, and the adsorption isotherms and kinetics were described by Langmuir and second-order models, respectively. In-situ polymerization of pyrrole was a promising approach to enhance the adsorption activity of Mg-Al LDO for dye removal from wastewater.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
