“…With an energy of ∼2.7 eV, g-C 3 N 4 has excellent thermal-to-chemical stability due to its tri-s-triazine-type structure and can act as a visible light-powered catalyst. [17][18][19][20][21] However, the activity of single-component semiconductor photocatalysts is limited by factors such as a limited spectral response, high carrier recombination rate, and low quantum yield. To overcome these limitations, researchers have combined different semiconductors to form nanostructures that offer maximum light absorption and optimal electronic alignment.…”

Among the perovskite oxide community, La‐based perovskites have garnered considerable interest due to their remarkable properties including catalytic, electrocatalytic, photocatalytic, sensing, electrical, magnetic, and optical characteristics. Herein, rhodamine‐B (RB) dye has been reported to be sono‐catalytically decomposed by an ultrasound‐assisted advanced oxidation process (AOP) using perovskite‐type LaMnO3 (LMO) nanospheres synthesized via ultrasonic approach. Several physiochemical characterizations such as XRD, FT‐IR, XPS, SEM, TEM, and SEM‐EDS investigations were used to investigate the LMO perovskite nanospheres. Then, LMO potential for adsorption and the sonocatalytic decolorization of RB dye in an aqueous solution are examined. With LMO perovskites, the adsorption and removal kinetics of RB correspond to the pseudo‐first‐order model. Furthermore, by utilizing the pseudo‐first‐order, the RB dye process is removed with improved efficacy in the following sequence: Agitation alone: 3.76 x 10‐4 min‐1 < US only: 5.02 x 10‐3 min‐1 < LMO only: 5.85 x 10‐3 min‐1 < LO@MO + US: 1.38 x 10‐2 min‐1 < LMO + US: 1.75 x 10‐2 min‐1, accordingly. Perovskite‐type LMO, which has significant reusability and stability, is an ensuring sonocatalyst for dye decomposition in wastewater, enabling faster decolorization. A prospective mechanism has been suggested for the sonocatalytic decomposition of RB.
