In this work, a heterogeneous photocatalysis system is fabricated for treating wastewater containing organic dyes and pharmaceutical substances. Double-heterojunction Janus photocatalysts are formed on the surface of size-tunable polydimethylsiloxane (PDMS) microparticles shaped via simple low-cost coflow microfluidic devices. Ag0/Ag0-TiO2/TiO2 Janus-like synthesized porous PDMS as support in which metal–semiconductor heterojunction Ag0/Ag0-TiO2 second Ag0-TiO2/TiO2 created situ, leading to formation Ag0/Ag0-TiO2/TiO2@PDMS systems. To form heterojunctions surface, polymer chain etching method employed desired strategy have half TiO2 nanoparticles microparticles, treated by Ag source. Using salt additives method, made porous, providing more area photoreactions. Surprisingly, highest decomposition efficiencies 94.4 91.1% achieved rhodamine B(RhB) tetracycline (TC), respectively, under visible light 60 min pH 11, source at distance 2 cm, 5 mM AgNO3, 10 wt % TiO2, 7 NaCl, 20 gm/L photocatalyst, conditions that result best performance RhB degradation. Regarding stability photocatalysts, no significant change observed after five cycles.
