Solar photocatalytic degradation of pesticides over TiO-rGO nanocomposites at pilot plant scale.

Two TiO-rGO nanocomposites were prepared by hydrothermal method from commercial TiO (P25 and Hombikat UV100, HBK). In both cases TiO nanoparticles appeared intimate and homogeneously distributed on rGO surface, but forming a dense network in P25-rGO nanocomposite, and a more open structure in HBK-rGO. Zeta potential and particle size distribution favored the ease of HBK-rGO nanocomposite to form stable suspensions.
