Unveiling The Multi Functionality of CeCuIn2O5 Nanoparticles: A Promising Approach For UV-Light Photocatalysis, Electrochemical Sensing and Antibacterial Applications

CeCuIn2O5 trimetallic oxide nanoparticles (CCI NPs) were synthesised in the current work and examined for antibacterial activity against Methicillin Resistant Staphylococcus Aureus (MRSA), photocatalytic degradation of malachite green (MG) and electrochemical sensing of sodium nitrite. The physicochemical characteristics of the CCI NPs were analyzed using XRD, SEM, EDX, UV-vis and DLS method which depicts the morphology, crystalline nature and particle size synthesised CCI NPs. With a linear range of 0.8-4.8mM, the glassy carbon electrode (GCE) modified CCI NPs demonstrated an outstanding electrochemical response for sodium nitrite (NaNO2). In addition, the synthesized CCI NPs showed high photocatalytic activities for the degradation of MG dye in water. It indicates the CCI NPs material produces hydroxyl ((OH)-O-& sdot;) and superoxide (O-2(-)) radicals for MG degradation when exposed to UV light, also showed an efficiency of 89.6% towards the degradation of Malachite Green. Carried out the dose-dependent method to the standard antibiotic streptomycin at 10 g/disc (5, 7, 15, 20, 25 & 30) with a zone of inhibition (ZOI) of 25.27- 45.27 +/- 0.09 in mm CCI NPs showed excellent antibacterial activity against MRSA in a dose-dependent method. As a consequence, it was found that CCI NPs are an effective multifunctional material that can be scaled up for the quantification of NaNO2, photocatalytic dye degradation of malachite green, and antibacterial activity against MRSA.
