Abstract

Hydrogen is considered a primitive yet efficient gas that changed the quest for biofuels. Nanotechnology is a game changer in broader science applications and shows perspective in biohydrogen production from algae sources. This review focuses on biohydrogen production from microalgae and examines various fermentative methodologies. The potential impact of nanosized metals on the yield is discussed. A survey on the importance of metal oxidation states is also presented. Furthermore, the significance of metal nanoparticles (MNPs) in photofermentation (PF) and dark fermentation (DF) is reviewed, and their immobilization techniques are examined. Additionally, investigations on the catalytic abilities of transition metals such as Ni, Co, and Fe, noble metals such as Ag and Au, and photosensitizing transition metal compounds such as TiO₂ and CdS are explored. Moreover, synergistic MNPs and their loading ratio importance are expressed. Furthermore, key points for choosing MNPs and targeting hydrogen yield in PF and DF conditions are emphasized. Conclusive strategies for continuous biohydrogen yield are also elaborated.

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
