• ZrO2 @g-C3N4 photocomposite has been prepared from ZrO2 nanoparticles and g-C3N4 nanosheet using methanol via the ultrasonic method. The prepared photocomposite was characterized using XRD, TEM, EDX, DRS, FTIR, and XPS techniques and compared with pure ZrO2 and g-C3N4. A comparative study between the photocatalytic performance of the nanocomposite prepared material with ZrO2 and g-C3N4 used to degrade indigo carmine (IC) dye in an aqueous suspension has been developed. The experimental photodegradation data were asserted to conform to the Lagergren kinetics model, and the fabricated nanocomposite registers a higher rate constant and lower half-life time than pure g-C3N4. The findings showed that ZrO2 nanomaterials were adequately predisposed on the g-C3N4 surface, resulting in an expanded surface area and lowering band-gap energy. Furthermore, ZrO2 @g-C3N4 heterojunctions fabricated was hindered the recombination of superoxide radicals, electrons, and holes and resulted in the magnified photodegradation of IC dye. •ZrO2 @g-C3N4 nanocomposite was ultrasonically fabricated using the precursors ZrO2 and g-C3N4.•The anchoring of ZrO2 and g-C3N4 was verified by XPS, XRD, and EDX techniques.•The nanocomposite has proficiently degraded the indigo carmine dye during a visible-light-driven process.•A Z-scheme model was suggested for the enhancement as confirmed through the •O2− and h+ involvement.
