“…In recent years, semiconductor photocatalysts have manifested promising potential for the production of clean hydrogen (H 2 ) fuel via water splitting and for the removal of various toxic pollutants from wastewater under solar illumination [1][2][3][4][5][6][7]. Notably, perovskite metaloxide lanthanum ferrite (LaFeO 3 ) with relatively narrow band gap (∼2.34 eV) as compared to titania (TiO 2 ) photocatalyst, has emerged as a promising photocatalyst because of its visible-light responsive photocatalytic activity, non-toxicity and excellent structural stability under the photochemical reaction conditions [8][9][10].…”
