摘要: Abstract The reduced Graphene Oxide (rGO) supported TiO2 (rGO@TiO2) as the photocatalyst was synthesized and evaluated. oxided using chemical method AFM measurements showed that thickness of as-synthesized GO 3–5 nm which indicates 4–6 layers resultant graphene oxide. BET surface area 62.4 m2/g for 247.3 m2/g rGO@TiO2. Size distribution when rGO ratio increases from 5% to 15% (rGO/TiO2), rGO@TiO2 samples show better size in range 100 nm 200 nm. Photocatalysis test exposure time increased over 100 min, degradation rate could reach 96.4%. First order kinetics results much higher constant than TiO2. Reproducibility can keep rates at less 25 cycles. Results is a promising with long cycling life.
