Synthesis and catalytic practicality of titania@ITO-grown nanoflakes: an excellent candidate for isopropanol conversion to acetone

Abstract

Highly effective, remarkable and discerning isopropanol conversion to acetone has been achieved by a heterogeneous catalytic transfer oxidative hydrogenation of isopropanol using NaBH 4 in the presence of active titanium oxide nanoflakes (TiO 2 NFs) grown over ITO substrate for the first time followed by liquid-phase deposition protocol. Various sophisticated techniques were employed for the confirmation of well-shaped novel anatase nanoflakes, having small size and thickness of 5–10 and 30\xa0nm, respectively, consequently providing high surface area and greater density active sites enable the particles to be extremely active for the catalytic reaction. These exceedingly active nanoflakes proved to be good candidate showing remarkably high heterogeneous catalytic efficiency by converting approximately 100% isopropanol to acetone within 40\xa0s using 0.5\xa0mg TiO 2 NFs deposited over ITO surface. Various parameters are optimized, e.g., time, dose, concentration of reducing agent and isopropanol for this rapid and effective conversion. These synthesized nanoflakes are of finest choice in terms of cheapest source, high catalytic efficiency, exceptional reusability and good analytical practicality with maximum yield in very short time.
