Photocatalytic properties of SnO2–SnO nanocomposite prepared via pulse alternating current synthesis

A SnO₂–SnO nanocomposite was electrochemically synthesized using pulse alternating current and characterized by XRD, SEM, TEM, UV-VIS DRS, and lowtemperature N₂ adsorption/desorption (BET) methods. The photocatalytic activity of nanocomposite was estimated for the degradation of methylene blue dye. The pseudo-first-order reaction constant rate k was calculated to be 79.1×10⁻³min⁻¹.
