Summary: An efficient and facile method for synthesizing BiVO4/reduced graphene oxide (BiVO4/rGO) photocatalyst via a one-pot hydrothermal process was developed. Ethylene diamine tetraacetic acid disodium salt (EDTA-2Na) was used instead of nitrate to provide an acidic environment, preventing the hydrolysis of Bi3+ and increasing the safety of the process. Loading BiVO4 on rGO significantly enhanced the photocatalytic activities, with a degradation efficiency of Rhodamine B (rhB) reaching 98.3% in 180 minutes. This work provided an ideal method for stable, efficient, and recyclable photocatalysts suitable for the visible light range.

Summary: In this study, zinc-oxides with three different morphologies were synthesized using the hydrothermal method. The synthesized products were characterized using EDX, SEM, XRD, FT-IR, and BET analysis. It was found that the ZnO-2 microparticles had a significantly higher surface area compared to previous studies. The catalytic performance of these zinc-oxides was evaluated for the reduction of 4-NP, a hazardous compound released in wastewater, and it was observed that the morphology and surface area of the zinc-oxide microparticles affected the reduction efficiency.

Summary: Fe3O4@C@DETA is a novel amino-functionalized magnetic adsorbent developed for the removal of Cr(III) and Cr(III)-EDTA from wastewater. It exhibits enhanced adsorption capacity due to the introduction of amino active sites, and can be easily separated by external magnetic field and regenerated in acidic solution with over 75% efficiency. Additionally, the adsorbent has good recyclability and can be repeatedly used in the adsorption process.

Summary: This study investigated the competitive adsorption behavior and selective removal mechanisms of coexisting EDTA-complexed heavy metals (EDTA-CHMs) on an adsorbent. The results showed that Ferrihydrite (Fh) had a higher adsorption capacity for EDTA-Cu(II) compared to EDTA-Cr(III). The adsorption performance of Fh for EDTA-Cu(II) was consistently stronger, regardless of the ratio and addition order of the coexisting EDTA-CHMs.

Summary: This study demonstrates the control over lattice structures and domain sizes of MXene-derived TiO2 crystallites by adjusting oxidation conditions, pH, and temperature. The preference for anatase phase over rutile phase is observed in basic and hot oxidizing solutions, while the portion of rutile phase increases at lower pH and temperature.

Summary: Wastewater from the textile industry, which contains various organic dyes, poses a chronic and hazardous problem for human health. A study conducted on the treatment of this wastewater using low-cost and efficient photocatalyst technology found that ZnO microstructures grown in the presence of psyllium husk showed enhanced photocatalytic activity towards the degradation of methylene blue. The psyllium husk modified the surface of the ZnO microstructures, created defects in the crystal structures, and altered the morphology of the nanostructured material. The addition of carbon from the thermal combustion of psyllium husk further improved the photocatalytic performance. The research also explored the optimal dosage of photocatalyst for efficient photodegradation of methylene blue.

Summary: In this study, the carrier dynamics in CsPbBr3 microrods and microplates were investigated using femtosecond transient absorption spectroscopy. A giant band-gap renormalization effect was observed, resulting in large transient band-gap shrinkages. The dynamic processes of thermalization and cooling, band-gap renormalization, defect-assisted recombination, and Auger recombination were identified and analyzed using a phenomenological model. The time constants for band-gap renormalization and defect-assisted recombination were found to depend on pump fluence and probe wavelength. These findings provide new insights into the morphology-related carrier dynamics in CsPbBr3 microstructures.

Summary: In this study, alpha-FeOOH nanoparticles were synthesized using a hydrothermal assisted method. The synthesized nanoparticles showed good adsorption capacity for Pb(II) and IDC at pH 10 and 4, with intraparticle diffusion and pore filling mechanism playing a dominant role in the adsorption process. The adsorption onto the alpha-FeOOH nanoparticles was found to be an endothermic reaction.

Summary: The magnetic field serves as a special substance that objectively exists and transmits magnetic force between objects, providing enhancement for pollutant adsorption. By adjusting the type and parameters of the magnetic field, adsorption efficiency and selectivity can be improved. Currently, there is a research gap in the area of pollutant enhanced-adsorption technique using magnetic fields.

Summary: This study investigated the interfacial microstructures and adsorption mechanisms of benzohydroxamic acid (BHA) on Pb2+-activated cassiterite (1 1 0) surface using Raman spectroscopy, AFM, XPS, HRTEM, and DFT calculations. The results showed that the major surface species was the Pb-BHA complex, and BHA could also chemically adsorb on the surface. Raman spectra and HR-TEM images further supported these findings.

Summary: Current lignin conversion techniques face the challenge of low carbon utilization efficiency due to the generation of residual solid (char). Therefore, understanding the pathway for char formation is crucial for lignin valorization. This study provides mechanistic insights into char formation in lignin depolymerization through hydrothermal decomposition. The results suggest that the char consists of a multi-layer construction of coke and oligomer, primarily derived from native G-lignin and demethoxylation of S-lignin, while H-lignin contributes to the formation of volatile monophenols. Additionally, new methylene bridges form between the benzene rings in lignin, leading to the formation of recalcitrant char. A plausible mechanism for char formation is proposed and verified using density functional theory calculation.

Summary: Zeolite LTA is a significant industrial zeolite, and the synthesis of zeolites using natural resources or manufacturing wastes as raw materials has economic and environmental benefits. However, soluble impurities in these feeds influence the quality of zeolite LTA products, and the effects of different inorganic salts on the phase transformations in zeolite LTA have been studied using in situ synchrotron powder X-ray diffraction.
