ABSTRACT
Crude oil-based gasoline fuels have been widely used in the transportation sector since the 1920s. However, there have been great public concerns over the adverse environmental and human impact of these fuels. Hence, biomass-based bioethanol fuels have increasingly been used in blending gasoline fuels and in fuel cells. In the meantime, the research in nanomaterials and fuel cells has intensified in recent years. Furthermore, the research in hydrogen fuels has also intensified in the primary research fronts of water-based photocatalytic hydrogen production, water-based electrocatalytic hydrogen production, reforming of bioethanol fuels for the production of biohydrogen fuels, biohydrogen fuel production, and hydrogen storage with more focus on nanomaterial development for hydrogen production and storage in recent years. Thus, the research in the field of the production of biohydrogen fuels from bioethanol fuels has progressed in the research fronts of biohydrogen production by steam reforming of bioethanol and to a lesser extent by photocatalytic biohydrogen production from bioethanol fuels, the oxidative steam reforming of bioethanol fuels, the partial oxidation of bioethanol fuels, autothermal reforming of bioethanol fuels, and biohydrogen production from bioethanol fuels in general. However, it is essential to develop efficient incentive structures for the primary stakeholders to enhance the research in this field. This chapter presents a scientometric study of the research in bioethanol-based biohydrogen fuels. It examines the scientometric characteristics of both the sample and population data presenting scientometric characteristics of both these datasets in the order of documents, authors, publication years, institutions, funding bodies, source titles, countries, Scopus subject categories, keywords, and research fronts.
