LaCoxFe1-XO3 (0≤x≤1) spherical nanostructures prepared via ultrasonic approach as photocatalysts

To harvest the photon energy, a sequence of perovskite-type oxides of LaCoxFe1-xO3 (0 ≤x≤1) nanostructures with distinct ‘Cobalt’ doping at the position of B-site are successfully prepared via a simple ultrasonic approach as photocatalyst. The crystallinity, phase identification, microstructure, and...
