Highest degradation of aromatic dyes by new MgO@PANI-o-PDA core–shell nanocomposites

Because of tremendous demand of different, innovative and convenient synthetic techniques, the present research establishes a remarkable synthetic protocol for new core–shell nanocomposites (CSNCs) containing magnesium oxide. MgO@poly(aniline-co-o-phenylenediamine) (MgO@PANI-o-PDA) CSNCs were generated employing equimolar ratios of the applicable moieties and several MgO weights through polycondensation. The CSNCs structures were confirmed by varied characterizations. The linkage between MgO and PANI-o-PDA was detected through FTIR bands. The CSNCs characters have core–shell structures as well as small size 41–66 nm. Under irradiation, the CSNCs afford the highest photocatalysis efficacy toward MB dye degradation. Realistic explanations of the photocatalytic efficiency results of CSNCs toward MB were substantiated. From DLS results, the CSNC system is either one of the good or the best systems having narrow PDI and incipient instability. This pathway is an original, simplistic, economical and advantageous procedure to develop potential CSNCs in the objective of pioneering constructions. Graphic abstract
