“…Figure 3 illustrates the XPS spectra of Mn(2p), Ti(2p), and O(1s) core levels of MTO nanodiscs. The XPS spectrum of Mn(2p) was fitted via the Voigt function to accurately define the double peak features of Mn (2p 3/2 ) and Mn (2p 1/2 ) core levels [ 30 ]. The deconvoluted XPS of Mn(2p) ( Figure 3 (a)) displays 4 peaks positioned at binding energy (B.E.)…”

MTO nanodiscs synthesized using the hydrothermal approach were explored for the photocatalytic removal of methylene blue (MB), rhodamine B (RhB), congo red (CR), and methyl orange (MO). The disc-like structures of ~16 nm thick and ~291 nm average diameter of stoichiometric MTO were rhombohedral in nature. The MTO nanodiscs delivered stable and recyclable photocatalytic activity under Xe lamp irradiation. The kinetic studies showed the 89.7, 80.4, 79.4, and 79.4 % degradation of MB, RhB, MO, and CR at the rate constants of 0.011(±0.001), 0.006(±0.001), 0.007(±0.0007), and 0.009 (±0.0001) min −1 , respectively, after the 180 min of irradiation. The substantial function of photogenerated holes and hydroxide radicals pertaining to the dye removal phenomena is confirmed by radical scavenger trapping studies. Overall, the present studies provide a way to develop pristine and heterostructure perovskite for photocatalysts degradation of various organic wastes.
