Biochars were produced via pyrolysis at 450, 550, and 650 °C, yielding samples labeled SSB1, SSB2, and SSB3, respectively. The production of glycerol carbonate through the transesterification of glycerol and dimethyl carbonate (DMC) was selected as a model reaction to evaluate the catalytic efficacy of these biochars. This approach aligns with the principles of green chemistry, addressing the effective utilization of biomass waste and excess glycerol while contributing to a circular economy. Characterization using FTIR, XRD, TGA, N₂ adsorption, and SEM-EDX analyses revealed significant effects of pyrolysis temperature on the physicochemical properties of the biochars, including yield, pH, surface area, and mineral content. Higher pyrolysis temperatures led to increased porosity, surface area, and mineral content, which enhanced catalytic performance. Under optimized conditions, the catalytic activity of SSB1, SSB2, and SSB3 was evaluated at a reaction temperature of 110 °C, a catalyst loading of 5 wt%, a reaction period of 20 min, and a DMC-to-glycerol molar ratio of 5:1. Among the biochars, SSB3 demonstrated the highest catalytic activity, achieving a glycerol conversion rate of 65.3% and glycerol carbonate selectivity of 53.4%. By linking the structure-performance relationship, this paper highlights the innovation and logic of utilizing biochars as effective catalysts in heterogeneous processes.

Among the avrious remediation methods, photocatalysis is considered optimal due to its efficiency and eco-friendly nature. Therefore, the development of highly active, visible-light-responsive, and noble-metal-free photocatalysts for the elimination of toxic heavy metal ions from wastewater is highly desirable. In this study, a facile two-step method, comprising solvothermal and hydrothermal, was used to synthesize visible-light-responsive CdS/MoS<sub>2</sub> heterojunctions (CM-HJs). Extensive structural characterization was performed to assess the crystal structure (XRD and XPS), morphology (SEM and BET), and optical (UV-Vis) properties of the as-synthesized photocatalysts. Aquatic Cr(VI) photoreduction was conducted on these photocatalysts under visible light irradiation. The results revealed the high photocatalytic activity and photostability of CM-HJs for Cr(VI) reduction compared to the bare CdS. Among the heterojunctions, CM-10 (10 wt % MoS<sub>2</sub>) exhibted the highest acvtivty, reducing 99.04% of Cr(VI) within 60 min. The enhanced photocatalytic activity can be attributed to its high light harvesting capability and efficient separation and transportation of the produced electron-hole pairs due to the intimate contact interfaces and matching band potentials of CdS with MoS<sub>2</sub>. Based on the literature and experimental evidence, a photocatalytic mechanism for the photoreduction of Cr(VI) is discussed in detail. The effect of different parameters; like the amount of photocatalyst, amount of Cr(VI), and pH were also evaluated.

In this study, a modified montmorillonite based catalyst is employed for the synthesis of 2,3-dihydroisoxazolo[5,4-<i>d</i>] pyrimidin-4(7 H)-ones, which are promising candidates for anticancer agents. Montmorillonite is modified using mixed metal oxides, typically Al<sub>2</sub>O<sub>3</sub> and CeO<sub>2</sub>, by a facile approach followed by standard spectroscopic and electron microscopic characterizations. It is then employed for the one-pot synthesis of a series of 2,3-dihydroisoxazolo[5,4-<i>d</i>] pyrimidin-4(7 H)-ones. The synthesis protocol, mediated by ultrasound, is simple, efficient, and environment friendly. The mixed metal oxide pillared montmorillonite catalyst exhibits high catalytic activity and selectivity, facilitating the formation of the desired compounds in good to excellent yields. The synthesized compounds are characterized using various spectroscopic techniques such as <sup>1</sup>H NMR, <sup>13</sup>C NMR and mass spectrometry. Furthermore, the anticancer activity of the synthesized compounds is evaluated against a series of cancer cell lines, revealing promising cytotoxic effects. The findings of this study highlight the potential of novel 2,3-dihydroisoxazolo[5,4-<i>d</i>] pyrimidin-4(7 H)-ones as promising anticancer agent, warranting further investigation for their therapeutic potential.</p></div>","PeriodicalId":509,"journal":{"name":"Catalysis Surveys from Asia","volume":"28 4","pages":"435 - 451"},"PeriodicalIF":2.1,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
