Effect of reactant concentration on the physicochemical properties of nanosized titania synthesized by microwave-assisted continuous flow method

Nanosized Titania was prepared through a microwave assisted continuous flow method. Initially, the samples were characterized by XRD, TEM, BET, FTIR, UV–Visible and photoluminescence (PL) spectroscopy. Then the effect of titanium-n-butaoxide (TBO, Ti4+ precursor) concentration on the physicochemical...
