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.</div></div>","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":"27 24","pages":"Pages 7009-7041"},"PeriodicalIF":9.3,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","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":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HHP instruments are safe and easy to handle, robust, and are a good fit for batch and (stopped)-flow operations. The same instruments could be used for large scale chemical synthesis as well, however, the high pressure synthesis of organic compounds, including Active Pharmaceutical Ingredients (APIs), is still in its infancy with extensive developments expected in the near future. HHP applies mechanical compression force to initiate transformations, such as the inactivation of pathogens and enzymes, or activation of chemical reactions. The pressure range of these reactions (2–20 kbar) significantly exceeds that of the typical chemistry using pressurized gases (0.01–0.1 kbar), such as hydrogenations.

In this study, we have developed an innovative Co–ReO<sub><em>x</em></sub> catalyst (Co/ReO<sub><em>x</em></sub>-LDO (layered double oxides)) through a hydrothermal impregnation approach. This catalyst facilitates the direct and selective conversion of PET into <em>p</em>-xylene (PX) under mild conditions, achieving yields and productivities as high as 71.7% and 1.1 mmol g<sup>−1</sup> h<sup>−1</sup>, representing a 3.0-fold improvement compared to the CoAl-LDO catalyst. The Co/ReO<sub><em>x</em></sub>-LDO catalyst demonstrates remarkable recyclability and broad applicability across various esters. Characterization studies reveal that the robust Co–ReO<sub><em>x</em></sub> interaction results in smaller Co particle sizes and higher charge densities, which effectively suppress ring hydrogenation and C–C bond cleavage. Meanwhile, the adjacent ReO<sub><em>x</em></sub> sites promote hydrogen spillover, significantly enhancing the reactivity of Co–ReO<sub><em>x</em></sub>. Spectroscopic analyses indicate that the rate-determining step involves C–O bond cleavage of the ester linkage to form acyl intermediates, and Co–ReO<sub><em>x</em></sub> accelerates this process with a reduced energy barrier.

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.</div></div>","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":"27 24","pages":"Pages 7319-7328"},"PeriodicalIF":9.3,"publicationDate":"2025-05-28","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}
