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 impacts of these fuels. Hence, biomass-based bioethanol fuels have increasingly been used in blending gasoline fuels and in fuel cells. In the meantime, research in nanomaterials and fuel cells has intensified in recent years. Furthermore, 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 and other fuels for the production of biohydrogen fuels, biohydrogen 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 the steam reforming of bioethanol and, to a lesser extent, photocatalytic biohydrogen production, biohydrogen production by the oxidative steam reforming of bioethanol, biohydrogen production by the partial oxidation of bioethanol, autothermal reforming of bioethanol, and biohydrogen production from bioethanol in general. However, it is essential to develop efficient incentive structures for the primary stakeholders to enhance research in this field. Although there have been a number of review papers on the bioethanol-based production of biohydrogen fuels, there has been no review of the 25 most-cited articles in this field. This chapter presents a review of the 25 most-cited articles in the field of bioethanol-based biohydrogen fuels. Then, it discusses the key findings of these highly influential papers and comments on future research priorities in this field.
