Ultrasound assisted dispersion of Bi2Sn2O7-C3N4 nanophotocatalyst over various amount of zeolite Y for enhanced solar-light photocatalytic degradation of tetracycline in aqueous solution.
TL;DR: The zeolite served as a support that prevented the accumulation of Bi2Sn2O7-C3N4/Y active phase and increased access to active sites and enhanced the adsorption capacity of tetracycline on the photocatalyst surface; that it is beneficial for tetrACYcline photocatalytic oxidation.
