“…Another persuasive technique for directly observing the SAC structure is by using Scanning Tunneling Microscopy (STM), in which the surface images of the conducting or semiconducting materials at the atomic level can be attained [251,252]. The typical advantage of STM is to in-situ track the reaction process on a well-defined surface and provides the opportunity to explore catalytic mechanisms in real time [253,254]. STM operates under ultra-high vacuum at the broadband temperature range from near − 273 • C to around 1027 • C [255,256].…”

The catalytic activity of nickel nanoparticles (5% Ni w/w loading) dispersed on different metal oxide supports has been explored for the hydrogenation of furfural. Nickel, supported on reducible oxides (CeO2 and TiO2), displays higher (almost 100%) conversion compared to that on non‐reducible oxide supports (SiO2, Al2O3, Mg3AlOx). H2‐TPR and XPS analyses bring out the influence of metal‐support interaction during the reduction of nickel precursor and their electronic properties. The adsorption and activation of furfural on the catalyst has been studied using infrared spectra and DFT calculations. The reaction proceeds via both ring‐rearrangement and ring hydrogenation pathways, with furfuryl alcohol as the primary intermediate. At higher reaction temperature, reducible oxide supported catalysts, particularly titania, favours deep‐hydrogenated products and higher conversion than non‐reducible oxide supported catalysts. Among all the catalysts, nickel on titania displayed maximum conversion of furfural. TiO2 possessing higher acidity than ceria, favoured ring‐rearrangement of furfuryl alcohol to cyclopentanone at high temperatures, while the latter retarded reduction of cyclopentanone due to blockage of active‐sites by unreacted furfural and strongly adsorbing intermediates. The combined effects of the electronic‐state of supported metal and surface acidity of catalyst provide a new strategy to tune catalytic properties for selective transformation during hydrogenation of furfural.
