Dry synthesis of water lily flower like SrO2/g-C3N4 nanohybrids for the visible light induced superior photocatalytic activity

In the present study strontium oxide/graphitic carbon nitride (SrO2/g-C3N4) nanohybrids was successfully synthesized by a facile simple dry synthesis and used for the photocatalytic degradation of organic contaminants for the very first time. The SrO2/g-C(3)N(4)nanohybridsare having a superior crystallinity and crystallite size was similar to 7.1 nm. The photodegradation efficiency of nanohybrids was tested on the degradation of RhB dye solution under visible light irradiation. TheSrO(2)/g-C(3)N(4)nanohybrids exhibited excellent photocatalytic activity, which may be attributed to the improved charge separation and complete degradation of the dye solution is achieved within 60 min. Moreover, the synthesized nanohybrids exhibited a good stability towards the photodegradation of RhB dye. Finally, the possible mechanism for the charge separation in thephoto degradationprocess was explored. Therefore, the nanohybrids are possessing potential interest in waste water treatment and environmental remediation under visible light irradiation. (C) 2017 Elsevier Ltd. All rights reserved.
