Silica fume, a by-product of industrial silicon and ferrosilicon alloy production, represents a hazardous waste with limited recycling options. In this study, sodium silicate synthesized via alkali dissolution was used as the starting material. High-purity silica powder was obtained by employing calcium oxide for impurity removal followed by a carbonation process. A single-factor experiment revealed that, under conditions of 60 °C, a reaction time of 3 h, and 6 g L−1 calcium oxide, the removal rates of aluminum and iron were 50.2% and 91.4%, respectively. Optimization using response surface methodology enhanced aluminum removal to 53.1%, while iron removal remained at 91.5%. In the carbonation experiment, conducted at 75 °C, with a pH of 9.0, a concentration of 60 g L−1, a CO2 flow rate of 40 mL min−1, and a stirring speed of 300 rpm, the silica recovery rate reached 92.4%, and the agglomerate particle size was 11.38 μm. Characterization techniques including XRD, FTIR, SEM, and XRF confirmed that the product was 99.79% pure amorphous silica. After further treatment with chelating agent purification and mixed acid leaching, the purity of the synthesized silica can reach 99.9914% (4N). This process offers significant environmental and economic benefits by recycling silicon-containing waste and reducing CO2 emissions.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 7191-7207"},"PeriodicalIF":9.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HTL is generally preferred for wet biomass, while fast/flash pyrolysis is more suitable for dried biomass, as moisture content plays a crucial role in determining the appropriate conversion method. Beyond moisture content, the biochemical and elemental composition of biomass significantly impacts the physical and chemical characteristics of the resulting liquid biofuels, often increasing the need for upgrading. This review provides a comprehensive comparison of HTL and fast/flash pyrolysis for converting five biomass types—lignocellulosic biomass, microalgae, macroalgae, municipal sludge, and food waste—into liquid biofuels, highlighting the impact of biomass composition on biofuel yield and quality. By linking biomass type, process severity, and liquid biofuel quantity, this study offers a structured framework for selecting the optimal conversion process and severity range to maximize biofuel yield in large-scale applications. Additionally, this review identifies various organic compounds and their concentrations in liquid biofuels produced through HTL and fast/flash pyrolysis from different biomass sources, serving as a valuable resource for developing novel multistage and selective upgrading processes.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 7009-7041"},"PeriodicalIF":9.3,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/gc/d5gc01314c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All of these oligoindoles have been identified as anti-cancer agents. However, access to these oligoindoles currently remains largely unreliable since their chemical synthesis and isolation from vegetables are challenging, cost-ineffective, and eco-unfriendly, thereby limiting their development. Herein, we present a horseradish peroxidase (HRP)-catalysed method for the synthesis of DIM, LTr1, LTe2, and LTr3 from indole-3-acetic acid (IAA) mixed with indole or its commercially available derivatives. Moreover, green chemistry metrics and EcoScale score evaluations supported the enzymatic method as a green protocol. By gaining insights into enzymatic mechanisms, which involve the radical–radical coupling reaction, the whole-cell biosynthesis of bioactive oligoindoles can be achieved. Altogether, the work provides an efficient access to cruciferous vegetable-derived oligoindoles, deepens our understanding of the application potential of HRP, and promotes further development of synthetic biology methods for DIM, LTr1, and LTe2.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 7319-7328"},"PeriodicalIF":9.3,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144291783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
