Synthesis, characterization, and photocatalytic activity of PPy/SnO2 nanocomposite

In this paper, Polypyrrole-tin oxide (PPy/SnO2) nanocomposite was prepared by the facile chemical polymerization technique and characterized using different techniques. From the powder XRD technique, the average crystallite size, crystallinity, and diffraction pattern of PPy/SnO2 were obtained. Four...
