Furfural is a biomass-derived platform molecule of growing interest for the production of renewable fuels and value-added chemicals, such as furfuryl alcohol (FOL) and 2-methylfuran (2-MF), via catalytic hydrogenation. In this work, copper-based nanocatalysts supported on ZnO, MgO, and Al₂O₃ were synthesized through a co-precipitation method adapted from the literature, aiming to provide an environmentally friendly alternative to the traditional copper chromite catalyst, known for its toxicity. The synthesized materials were characterized by transmission electron microscopy (TEM), nitrogen adsorption-desorption (BET method), and Fourier transform infrared spectroscopy (FTIR). TEM analysis revealed distinct morphologies depending on the support, including nanowire structures and core–shell configurations. The catalysts exhibited relatively low specific surface areas, ranging from 8 to 37 m2/g, consistent with reports for similar metal oxides.
