Highlights: • Water lily flower like SrO{sub 2}/g-C{sub 3}N{sub 4} nanohybrids have been successfully synthesized by a dry synthesis method. • TEM images confirmed that the water lily like morphology of SrO{sub 2}/g-C{sub 3}N{sub 4} nanohybrids. • The photodegradation of RhB dye solution was performed under the visible light illumination. • The SrO{sub 2}/g-C{sub 3}N{sub 4} nanohybrids showed excellent photocatalytic activity compared to pure g-C{sub 3}N{sub 4} and SrO{sub 2}. • Most important reactive oxidative species were found out by trapping experiment. - Abstract: In the present study strontium oxide/graphitic carbon nitride (SrO{sub 2}/g-C{sub 3}N{sub 4}) 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 SrO{sub 2}/g-C{sub 3}N{sub 4}nanohybridsare having a superior crystallinity and crystallite size was ∼7.1 nm. The photodegradation efficiency of nanohybrids was tested on the degradation of RhB dye solution under visible light irradiation. The SrO{sub 2}/g-C{sub 3}N{sub 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 wasexplored. Therefore, the nanohybrids are possessing potential interest in waste water treatment and environmental remediation under visible light irradiation.
