Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Liquid‐phase oxidation of furfural catalyzed by magnetically separable metal oxide nanoparticles deposited on silica gel

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Oxidation of furfural (FF), a bio‐based platform chemical, was investigated using a range of iron‐, vanadium‐ and iron–zinc‐oxalates supported on silica gel (FeVOx@silica and FeZnOx@silica, respectively) as precursor for FeV@silica and FeZn@silica oxide catalysts and H2O2 as a green oxidant.
