Fernand Fiévet,S. Ammar-Merah,Roberta Brayner,F. Chau,Marion Giraud,Fayna Mammeri,Jennifer Peron,Jean-Yves Piquemal,L. Sicard,Guillaume Viau +9 more
TL;DR: The scope of the polyol process has been extended to the preparation of more electropositive metals, such as post-transition metals and semi-metals, and the potential of this method is also clearly displayed for the prepared of alloys, intermetallics and core-shell nanostructures with a very large diversity of compositions and architectures.

Current status of hydrogen production techniques by steam reforming of ethanol : A review
TL;DR: In this paper, the current state of the steam reforming process of ethanol, examines different catalysts, and makes a comparative analysis, and concludes that Co/ZnO, ZnO+Al2O3, Co/CeO2, Ni/La 2O3−Ni/La2O2−Al2E3, and Ni/E3−E2E2−E3 performed the best in terms of steam reforming of ethanol.
