The efficient conversion of seaweed into mesoporous β-MnO<sub>2</sub>@SARC was accomplished through a direct pyrolysis technique performed under inert atmospheric conditions at various temperature ranges (700 °C–900 °C).

The optimal H<sub>2</sub> yields predicted for the model were obtained for HWPs at 550/700 °C (26.67 g H<sub>2</sub>/kg dry biomass), followed by SWPs at 550/700 °C (24.11 g H<sub>2</sub>/kg dry biomass) and WSPs at 550/685.2 °C (18.78 g H<sub>2</sub>/kg dry biomass). The volumetric syngas yields were highest for HWPs at 550/700 °C (0.831 Nm<sup>3</sup>/kg dry biomass), followed by SWPs (0.777 Nm<sup>3</sup>/kg dry biomass) and WSPs (0.634 Nm<sup>3</sup>/kg dry biomass). This study demonstrates that regression modelling accurately predicts H<sub>2</sub> and syngas yields, which would help to expand the applicability of TCR technology for large-scale hydrogen production, contributing to the decarbonization of the energy sector.</div></div>","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"204 ","pages":"Article 108375"},"PeriodicalIF":5.8,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145056793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
