Summary: Ternary BiOCl/C/Cu2O catalysts with different mass ratios were synthesized using a simple hydrothermal method and exhibited better photocatalytic activity than the monomer. The 25% BiOCl/C/Cu2O catalyst showed optimal performance with CO and CH4 yields 2.9 and 8.7 times higher than pristine Cu2O, respectively. This improvement can be attributed to the Z-scheme heterostructure and carbon layer, facilitating the transfer and separation of photogenerated carriers. This study provides valuable references for the design and investigation of Z-scheme heterojunctions using carbon layer as an electron transfer medium.

Summary: This study investigated the structural stability of carbon-based catalysts, specifically g-C3N4 and modified g-C3N4, during peroxymonosulfate (PMS)-based advanced oxidation processes (AOPs). It was found that both g-C3N4 and modified g-C3N4 partially decomposed in the PMS-based AOPs, leading to carbon dissolution in solution. The dissolved carbon from modified g-C3N4 showed higher concentration than that from pristine g-C3N4 and exhibited acute toxicity.

Summary: Understanding the mechanism of acrolein formation during propylene oxidation on Au/uncalcined TS-1 catalyst is important for understanding oxygen activation and hydroperoxo species formation on Au sites. In this study, the formation of acrolein was found to be promoted by H-2 through hydroperoxo species formation on the Au/TS-1-B catalyst. This research provides insights for the propylene hydro-oxidation and facilitates the design of highly active and selective Au catalysts for direct propylene epoxidation.

Summary: Compared to other hydrogen production methods, biohydrogen produced from biological origin like microalgae is significantly less harmful to the surrounding ecosystem and can replace conventional fossil fuels without emitting greenhouse gases. Substrates like food, agricultural waste, and industrial waste can be easily utilized after pretreatment, increasing hydrogen yield. Improving biofuel production at each stage can have a significant impact, making it a potentially useful tool. Thus, this study comprehensively covers various approaches to pretreat algal biomass, enzymes and catalysts for hydrogen production, variables influencing hydrogen production, and the potential applications of genetic engineering.

Summary: The impact of carbon dioxide on global warming is a pressing issue that requires immediate attention for the sake of the Earth's ecosystem and humanity. Diminishing atmospheric CO2 concentration through conversion is an attractive solution, which can also lead to the formation of valuable compounds. The use of thermal hydrogenation as a method to achieve this goal requires a catalyst due to the high stability of the CO2 molecule. The designed materials should exhibit outstanding performance and stability, with high selectivity for CO and CH4.

Summary: The configuration and geometry of chemical reactors significantly impact performance evaluation and the development of thermodynamic and kinetic model reactions for photocatalytic materials. Lack of accurate transport profiles for mass, heat, and photons in photochemical reactors hinders comparison between experiments and standardization. This study proposes a compact stainless-steel photoreactor for hydrogen photoproduction and uses TiO2 Schottky junctions with Pd, Pt, or Au nanoparticles to validate the reactor's operation. Results show improved profiles and increased quantum yields compared to previous studies.

Summary: The demand for green and economically viable processes has boosted the research and development of Ordered Mesoporous Silicas (OMSs) using low-cost starting reagents. However, high production costs and environmental contamination remain as obstacles to the production of high quality OMSs. Waste utilization can help reduce costs and environmental impacts by reusing materials that have no other applications.

Summary: This study aims to design a tertiary graphitic carbon nitride (g-C3N4)-based photocatalyst for efficient production of benzaldehyde in an aqueous solution under mild conditions. Polymeric g-C3N4 was modified with the incorporation of boron and the deposition of ruthenium nanoparticles. The photocatalysts were fully characterized and their activity was assessed. Boron enhanced the selectivity, while ruthenium improved the reaction rate but negatively affected the selectivity. The sample containing 1% Ru was selected as the optimum in terms of selectivity. The contribution of reactive oxidant species was assessed, and band alignment analysis supported the enhancement of photocatalytic activity through increased redox potential of the released holes in the valence band.

Summary: The aim of this study was to extract and characterize silica materials from various agro-industrial wastes including sugarcane bagasse, corn stalk, and rice husk. The results showed that silica yields of 17.91%, 9.39%, and 3.25% were obtained for RH, CS, and SCB, respectively. The textural properties indicated that the siliceous materials had mesoporous structures, with SCB and CS forming crystalline SiO2 and RH forming amorphous. XPS spectra demonstrated the presence of Si4+ species in RH, and Si3+/Si4+ tetrahedra in SCB and CS.

The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
