Flat-Band Potential Determination and Catalytical Properties of SnO/SnO Heterostructures in the Photo-Electrooxidation of Small Organic Molecules under Ultraviolet (370 nm) and Blue (450 nm) Light.

SnO are promising semiconductor materials due to their visible light absorption ability. In this work, a series of materials, such as SnO, SnO and SnO/SnO heterostructures, with different phase ratios were prepared using hydrothermal synthesis. The materials were characterized using X-ray diffraction (XRD), Raman and diffuse reflectance spectroscopy (DRS), high resolution transmission electron microscopy (HRTEM), nitrogen adsorption (BET).
