Preparation of Ni-Fe layered double hydroxide/ graphitic carbon nitridenanocomposite for enhanced sonocatalytic degradation of tetracyclinehydrochloride

Pharmaceutical compounds, including antibiotics, are a major source of micropollutants inwater, leading to antibiotic-resistant pathogens and human health problems. Advanced OxidationProcesses (AOPs) [۱] and sonochemistry are effective methods to remove these pollutants.Layered Double Hydroxide (LDH) [۲] and graphitic carbon nitride (g-C۳N۴) are promisingmaterials for adsorption and degradation of heavy metals and pollutants. However, g-C۳N۴ haslow efficiency due to its structure and low utilization of visible light. To overcome this,researchers have loaded g-C۳N۴ [۳]with metal atoms and non-metallic elements, and fabricatedmicrostructures. The synthesis of NiFe_LDH/g-C۳N۴ double layered hydroxide nanocompositeshows potential for efficient sonocatalytic degradation of pharmaceutical pollutants. A NiFe-LDH/g-C۳N۴ nanocomposite was synthesized and used for sonocatalytic degradation oftetracycline from solution. The green conditions, simple catalyst preparation, and straightforward separation and recovery of the nanocomposite from the reaction mixture are the significantpoints of interest of this study
