Abstract
Delafossite materials demonstrate multifunctional applications due to their excellent catalytic properties, which vary depending on their morphology, particle size, and synthetic method. Herein, a few novel applications of the delafossites are reported, which can be implemented in commercial, medical, and domestic settings. In present work we are presenting two different delafossite CuGaO2 and CuFeO2 nanoparticles and its composite with cotton fiber. Multifunctional cotton fabric is prepared by depositing a uniform coating layer of CuGaO2 and CuFeO2, exhibits excellent photocatalytic self-cleaning, UV blocking, and antimicrobial activity. CuGaO2 and CuFeO2 nanoparticle concentrations of 1mM and 2mM were deposited over the cotton fabric using citric acid as a binder by a simple sonication method. Surface analysis, bindings, stability, stain resistance, and UV blocking characteristics of the functionalized cotton fabric are performed by SEM, EDX, XRD, FTIR, and UV-vis spectroscopy. Both CuGaO2-cotton and CuFeO2-cotton exhibit excellent photocatalytic activity, which is evident from the UV-Vis spectroscopic analysis after mixing with methylene blue dye and subsequent exposure to simulated solar light. 2 mM CuGaO2-cotton fabric has the highest rate of stain extinction compared to others. In addition, CuGaO2-cotton and CuFeO2-cotton block most of the harmful UV radiation, 95–97.5% (approx.) in the case of CuGaO2 and 90% (approx.) in the case of CuFeO2.
