Microbial immobilization is a promising strategy for various applications, including environmental remediation and bioprocess engineering. However, the efficacy of immobilization largely depends on the characteristics of the carriers. Biomass wastes are renewable and abundant resources that can be subjected to hydrothermal carbonization (HTC) for hydrochar production, a resulting carbonaceous material with a porous structure. This porous architecture offers extensive surface area and facilitates the colonization and growth of microorganisms, working as a protective buffer zone in highly polluted environments. This study points out the development of a novel biobased nano/micro-structured material for microorganism immobilization, integrating locally available feedstock for thermochemical conversion processes. To tailor a biobased porous material suitable for bacterial immobilization, the biomass waste was processed through HTC. The influence of main HTC parameters on biomass conversion was established. chemical, structural, and thermochemical analyses, encompassing proximate and ultimate analysis, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), chemical Composition Analyzer (EDS) and Thermogravimetric analysis (TGA), were conducted on both the feedstock and resulting hydrochar. SEM analyses revealed the nano/micro-structured morphology of the hydrochar, characterized by a wide distribution of pores ranging from nano to micrometer scale. A bacterial strain of Pseudomonas sp. was immobilized on hydrochar in order to evaluate the bacterial cell proliferation, their capacity and rate of forming stable colonies on the support material. The hydrochar obtained from locally biomass feedstocks represents an eco-friendly and sustainable biobased nano/micro-structured material, with promising applications in bioremediation and bioprocess engineering, thereby advancing green technologies and circular bioeconomy initiatives. © 2024 Internation

Climate change, global warming, and energy crisis have become an important problem due to the environmental impact of fossil fuels. Hence, alternate energy source is needed for environmental remediation. One such source could be hydrogen (H2). H2 is used as an alternate energy carrier due to it is non-toxic, clean, and efficient. Steam reforming of methyl alcohol (or) methanol (SRM) is a widely available and low-cost hydrogen production method. In this stream-reforming process, mostly commercial zinc-supported catalyst is used, these have some economic defect. Therefore, we need to find alternate suitable catalysts for the SRM process. In this study, ZnCrXFe2-XO4 (X = 0–2) porous catalyst powders of different ratios were synthesized by the glycine nitrate process (GNP) for hydrogen production by SRM. The specific surface areas of the ZnCrXFe2-XO4 powders ranged from 15.75 m2/g to 45.16 m2/g. The ZnCr0.4Fe1.6O4 powder had the highest H2 production without activation, reaching 6850.33 ml STP min−1 g-cat−1 at a reaction temperature of 450 °C. ZnCr0.4Fe1.6O4 porous powders prepared using the GNP method have simple, rapid process steps, low cost, high catalytic activity, and they can be applied to hydrogen fuel cells or other related catalysis applications in the future. The pure hydrogen production performance of these ZnCrXFe2-XO4 catalysts could be of great importance in industry and economic impact. © 2023 Hydrogen Energy Publications LLC
