| description | During this endeavor, a hetero structured photocatalyst of hexagonal boronnitride@ZnO-TiO
2
Nanocomposites that was effectively developed using the hydrothermal processing approach. The h-BN@ZnO/TiO
2
hybrid junctions substantially suppressed the conjugation of photoinduced electrons and vacancies, as well as the migration of voids through nanoparticles composed of ZnO/TiO
2
. Thereby, the h-BN@ZnO/TiO
2
nanocomposites exhibit improved photocatalytic capabilities and high resilience for the decomposed of methyl orange (MO) during visible light irradiation. Furthermore, the h-BN@ZnO/TiO
2
NPs exhibited superior MO removal efficiency of 99.2% in only 20 min which was approximately 20 times enhancement in photocatalytic activity compared to pristine h-BN under the visible light irradiation. This high degradation performance was attributed to the extended light absorption, narrowed band gap and effective suppression of electron–hole recombination through an addition of ZnO-TiO
2
NCs. According to the findings, a putative photocatalytic process of h-BN@ZnO/TiO
2
nanocomposites showed promise as an effective modern photo catalyst for use in the decomposition of organic pigments in sewage for environmental cleanup was postulated and addressed.
