Abstract

A facile technique was adopted to synthesize beautiful lilac bush resembling TiO2-SnO2 microflowers aggregates for photodegradation of Congo Red (CR). The TiO2-SnO2 microflowers in the 2-3 μm range with high surface area (80 m2/g), under optimized conditions of catalyst dosage (0.3 g/L), dye concentration (100 ppm) and pH value is 10, exhibit excellent photocatalytic activity under visible light, whereby, 98.3% of the CR aqueous solution was degraded in 40 min of illumination time and also shows good recyclable photocatalytic activities. Further, the gas sensing properties of the as-synthesized material were evaluated towards detection of a variety of volatile organic compounds, such as acetone, methanol, benzene, ammonia, toluene, diethyl ether, and ethanol.
