Abstract In this study Fe doped SnO₂-SnS₂ (FS) and Fe doped SnO₂-SnS₂-polypyrrole (FS-PPY) were synthesized and studied for the methylene blue (MB) egrdation under UV light. The morphological and structural characterizations were carried out by FTIR, SEM-EDX, XRD and XPS. It has been found that FS-PPy degrade methylene blue upto 98 % under optimized conditions as pH =3, dye concentration = 10 ppm, oxidant dose = 2 mM. The Langmuir-Hinshelwood kinetics model fitted well. The optimization was studied using response surface methodology. Scavengers study was carried out to find the active species. Reusability of photocatalyst was evaluated More >

Abstract Attapulgite clay-supported CdS composites were synthesized via hydrothermal approach and applied to remove Rhodamine B (RhB). The structural, morphological, and physicochemical properties of the materials were systematically characterized by XRD, TEM, XPS, BET and UV-Vis DRS. The combination of CdS and attapulgite could enhance active site availability and surface area, thereby boosting photocatalytic activity.The optimized CdS/attapulgite composite demonstrated remarkable photocatalytic efficiency under visible-light illumination. In addition, a potential photocatalytic degradation mechanism by the composites was proposed. More >

Abstract It is highly attractive for the catalysts prepared from renewable materials and/or industrial by-products. Herein, lignosulfonate (LS) as the by-product in the papermaking industry was utilized to fabricate Sn-containing organic-inorganic complexing catalysts (Sn(x)@LS) by a simple hydrothermal self-assembly process. The fabricated Sn(x)@LS played an excellent performance in the dehydration of xylose into furfural in the carbon tetrachloride (CTC)-water biphasic system, yielding 78.5% furfural at 180°C for 60 min. It was revealed that strong coordination between Sn⁴⁺ and the phenolic hydroxyl groups of LS created a robust organic-inorganic skeleton (-Ar-O-Sn-O-Ar-), simultaneously generating potent Lewis acidic sites, and More > Graphic Abstract

Abstract Background: Despite growing research on parental technology use and its impacts on adolescent development, the influence of parental smartphone behavior on creativity remains understudied. This study addresses this gap by examining how parental phubbing affects adolescent creativity, exploring both direct and indirect pathways through creative self-efficacy as a mediator and problematic smartphone use (PSU) as a moderator. Methods: A total of 9111 Chinese vocational school adolescents (60.3% male; mean age = 16.88 years) were recruited via convenience sampling. Participants completed validated self-report questionnaires assessing creativity, parental phubbing, creative self-efficacy, and PSU. A moderated mediation model… More >

Abstract This review presents a comprehensive and forward-looking analysis of how Large Language Models (LLMs) are transforming knowledge discovery in the rational design of advanced micro/nano electrocatalyst materials. Electrocatalysis is central to sustainable energy and environmental technologies, but traditional catalyst discovery is often hindered by high complexity, fragmented knowledge, and inefficiencies. LLMs, particularly those based on Transformer architectures, offer unprecedented capabilities in extracting, synthesizing, and generating scientific knowledge from vast unstructured textual corpora. This work provides the first structured synthesis of how LLMs have been leveraged across various electrocatalysis tasks, including automated information extraction from literature,… More >

Abstract Oat husks, a byproduct of oat milling operations with limited economic value, present a promising feedstock for biorefinery processes due to their chemical composition. This study investigates the conversion of C5 carbohydrates in oat husks into furfural through hydrothermal pretreatment using various phosphate-based catalysts, including H₃PO₄, NH₄H₂PO₄, NaH₂PO₄, KH₂PO₄, K₂HPO₄ and K₃PO₄ as catalyst. The catalysts’ effectiveness in promoting furfural production was evaluated under identical hydrothermal conditions (treatment time for 60 min at a constant temperature of 170°C and a catalyst amount). Continuous water steam was used to strip furfural from the reaction zone and minimize its degradation.… More > Graphic Abstract

Abstract Upgrading of abundant cellulosic biomass to isosorbide can reduce the dependence on limited fossil resources and provide a sustainable way to produce isosorbide, utilized for polymers, medicine and health care product synthesis. This review comprehensively examines the key steps and catalytic systems involved in the conversion of cellulose to isosorbide. Initially, the reaction pathway from cellulose to isosorbide is elucidated, emphasizing three critical steps: cellulose hydrolysis, glucose hydrogenation, and the two-step dehydration of sorbitol to produce isosorbide. Additionally, the activation energy and acidic sites during cellulose hydrolysis, the impact of metal particle size and catalyst More > Graphic Abstract

Abstract Photocatalytic synthesis of hydrogen peroxide offers an effective solution to the energy crisis. The design and development of high-activity and low-cost photocatalysts are crucial for H₂O₂ production. In this work, Zn_0.4Cd_0.6S with abundant S vacancies (S_V-ZCS) is developed for H₂O₂ photosynthesis under 405 nm LED illumination without additional cocatalysts. The S vacancies serve as photo-generated electron trap centers, effectively extending the lifetimes of photogenerated carriers and promoting the separation of photoelectric carriers. Additionally, S_V-ZCS is endowed with enhanced light capture capability, enhancing the overall photocatalytic activity for H₂O₂ production. The results were in line with expectations, the S_V-ZCS samples More >

Abstract Pure ZnS and Zn_1-xCr_xS nanoparticles were successfully prepared using the coprecipitation method, where x represents the concentration (x = 0.00, 0.10, and 0.05). There are many analytical methods used, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Spectroscopy of energy dispersive (EDS). The magnetism structure of the catalysts was investigated using spectrophotometry (VSM), thermogravimetric analysis (TGA), and differential thermal analysis (DTA). X-ray diffraction studies determine the nanocrystal arrangement and size of microcrystals. As seen in SEM analysis, the particles are agglomerated. The coordination of sulfur ions around zinc ions was examined using FTIR analysis.… More >
