“…Wet impregnation [ 32 , 40 – 44 ] and photodeposition [ 45 – 47 ] methods are frequently used for loading metals (e.g., Pt, Au or Pd) as the co-catalyst onto a TiO 2 support, with Pt the most commonly studied. As shown in Table 1 , the r H 2 of these noble metal loaded TiO 2 catalysts for photo-reforming of lignocellulosic materials are in the range of 100–1000 µmol h −1 g cat −1 .…”

Photocatalytic reforming of biomass has emerged as an area of significant interest within the last decade. The number of papers published in the literature has been steadily increasing with keywords such as ‘hydrogen’ and ‘visible’ becoming prominent research topics. There are likely two primary drivers behind this, the first of which is that biomass represents a more sustainable photocatalytic feedstock for reforming to value-added products and energy. The second is the transition towards achieving net zero emission targets, which has increased focus on the development of technologies that could play a role in future energy systems. Therefore, this review provides a perspective on not only the current state of the research but also a future outlook on the potential roadmap for photocatalytic reforming of biomass. Producing energy via photocatalytic biomass reforming is very desirable due to the ambient operating conditions and potential to utilise renewable energy (e.g., solar) with a wide variety of biomass resources. As both interest and development within this field continues to grow, however, there are challenges being identified that are paramount to further advancement. In reviewing both the literature and trajectory of the field, research priorities can be identified and utilised to facilitate fundamental research alongside whole systems evaluation. Moreover, this would underpin the enhancement of photocatalytic technology with a view towards improving the technology readiness level and promoting engagement between academia and industry.

In a world where fossil fuels are running out, biofuels are one of the best green energy alternatives to fuels made from petroleum due to their environmentally beneficial qualities and low cost in comparison with non-renewable fossil fuels. Biofuels are produced from cheap and renewable sources and the energy stored in these biomasses can be assimilated to create sustainable electricity or heat, which can then be exploited to meet current and future societal needs in numerous situations. However, the production of biofuels on an industrial scale takes a lot of time because of the numerous constraints placed on currently available technology and the increased costs that go along with them. Moreover, the processes utilized to transform various feedstocks into the desired output also vary based on the materials and techniques employed. The supply of biofuel feedstocks is large, and with improved processing, we could significantly lower our reliance on fossil fuels. In this context, the use of nanoparticles (NPs) is a commendable solution to the present problems with biomass use, especially given their low cost. The unique qualities of nanomaterials, such as excellent catalytic properties, high surface area-to-volume ratio, remarkable selectivity, and reusability make them admirable tools for boosting biofuel generation. This review predominantly focuses on the contributions of nanotechnology and various immobilization methodologies in accelerating biofuel production from biomasses that might fill in the research gap, which was previously limited by the relatively lower efficiency of traditional techniques of biofuel generation.

Biohydrogen has drawn the attention of researchers all over the world due to its advantages over conventional fuels. However, it is necessary to make the process of biohydrogen production economically and environmentally sustainable. In this study, biohydrogen production from soybean straw in anaerobic batch reactor (sera bottles) using H2 producing bacteria (Clostridium thiosulphatireducens and Enterobacter aerogenes) was investigated. Candidate strains were identified and analyzed by phylogenetic analysis. These bacteria were tested for their biohydrogen production singly as well as in combination. C. thiosulphatireducens, E. aerogenes and their co-culture inoculums were named as strain I, strain II and co-culture inoculum respectively. The fermentation process was carried out at 37°C at pH 6. Physico-chemical characteristics of substrate, cellulase enzyme activity, and 16S rDNA gene sequences were investigated. Maximum cellulase production was observed in co-culture inoculum which was 4.004 IU/ml. Maximum biohydrogen yield obtained was 1.39 mol of H2/g TS. By products formed during fermentation were acetic, butyric and propionic acid and formic acid. The analysis of variance (ANOVA) R2 value 0.843 indicates that 84.3% of variation in production of mol of H2 is explained by its relationship with microbial culture.
