Nanobinary (Mg-Al) and ternary (Ni-Mg-Al) metal oxy/hydroxides were synthesized by aerogel protocol. The key features of this method are homogenization of metal organic precursors in methanoltoluene mixture, controlled hydrolysis, gelation, hydrothermal treatment, and finally supercritical drying of solvent. The obtained materials, which on further drying at 120 °C, display high surface area, >500 m 2 g -1 , and smaller particle size, <20 nm. The samples were further characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric and differential thermal analysis (TG-DTA), and solid state 27 Al nuclear magnetic resonance (NMR). The ion exchange and catalytic properties of the resulting nanomaterials were compared with hydrotalcite-like layered double hydroxides (LDHs) prepared by a conventional coprecipitation method. The nanoternary system exhibits 2-4-fold increase in activity of pre-reforming of naphtha.
Ruthenium on a base support was developed for the conversion of biomass derived levulinic acid to γ-valerolactone at low temperature and pressure. γ-Valerolactone synthesis which can replace ethanol in petrol and in the production of jet fuels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
