Preparation of Ni-Fe layered double hydroxide/graphitic carbon nitride nanocomposite for enhanced sonocatalytic deterioration of tetracycline hydrochloride

NiFe layered double hydroxide/carbon nitride (NiFe-LDH/g-C3N4) nanocomposite was prepared by a hydrothermal methodology and its performance was investigated as catalyst for sonocatalytic decomposition of tetracycline hydrochloride (TCH), as a prime instance of a newly recognized pollutant in aqueous solution. FESEM, EDX, XRD, FTIR, BET, and TGA were performed on the synthesized samples to collect information about the morphology and structure of sonocatalyst. In order to show the sonocatalytic operational efficiency of NiFeLDH/g-C3N4 nanocomposite, the effect of the fundamental performance indicators on the deterioration of TCH was investigated. The best sonocatalytic effectiveness of 88.5 % was attained by employing 40.25 mg L-1 catalyst, 30.41 mg L-1 TCH and 349 W ultrasonic power at pH = 7.3 within 30 min. A proposed mechanism for the breakdown of TCH in the presence of NiFe-LDH/g-C3N4 nanocomposite within the sonocatalytic circumstances was also presented. The optimal sonocatalytic efficiency was evaluated by experimental design. The reusability assessment of the NiFe-LDH/g-C3N4 nanocomposite for the decomposition of TCH demonstrated consistent performance over five consecutive cycles, with no observable decline.
