Solvothermal Synthesis and Visible Photocatalytic Activity of Zn0.4Cd0.6S/TiO2/Reduced graphene oxide Nanomaterials

Abstract

Zn0.4Cd0.6S/TiO2/Reduced graphene oxide (Zn0.4Cd0.6S/TiO2/RGO) nano-photocatalyst was synthesized by a facile solvothermal method. During the reaction, TiO2 and Zn0.8Cd0.2S nanoparticles were evenly dispersed across the surface of RGO, which enhanced response to visible light. The photocatalytic activity of as-synthesized Zn0.4Cd0.6S/TiO2/RGO nanomaterial was studied by means of degrading methylene blue (MB) through the irradiation of visible light. Compared with other nanomaterials, the Zn0.4Cd0.6S/TiO2/ RGO nanomaterials showed the highest photocatalytic degradation efficiency (96%) and high stability, which was 5.4 times of photodegradation efficiency of pure TiO2.

Investigation an environmentally friendly method under magnetic field as a green solvent for the synthesis of brookite phase nanoparticles at room temperature

“…TiO 2 nanoparticle is one of the most proper and popular semiconductors whose applications cover diverse industrial areas including photocatalysis [1,2], thin-lm, sunscreen, photovoltaic, electrodes [3,4], sensors [5,6], and drug delivery [7,8]. In this regard, TiO 2 nanoparticle have been prepared through different methods, including sol-gel [9], inverse micelle [10,11], hydrothermal [12], straight oxidation [13][14][15], chemical vapor deposition [16][17][18], physical vapor deposition [19][20][21], electrochemical accumulation [22][23][24], sonochemical [25], microwave [26][27][28], and organometallic complex compounds [29][30][31][32][33][34]. However, almost all of the mentioned methods require high temperature (usually more than 500) [35].…”
