Abstract

Ceramic-polymeric 3C–silicon carbide-graphitic carbon nitride (3C–SiC@g-C₃N₄) nanocomposites were synthesized by decorating cubic phased, ceramic 3C-Silicon carbide (3C–SiC) on the framework of the nanosheets of metal free polymeric graphitic carbon nitride (g-C₃N₄) by single step pulsed laser ablation in liquid (PLAL) method. Morphological, structural, elemental and optical characterizations of the synthesized 3C–SiC@g-C₃N₄ nanocomposites were carried out. X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Transmission electron microscope (TEM) and high-resolution transmission electron microscope (HRTEM) studies confirm the perfect anchoring of 3C–SiC on g-C₃N₄ nanosheets in 3C–SiC@g-C₃N₄ nanocomposites synthesized by PLAL method. Ultra-violet diffuse reflectance spectra (UV-DRS) of 3C–SiC@g-C₃N₄ indicated the enhancement of visible light absorption and also the narrowing down of band gap energy in 3C–SiC@g-C₃N₄ nanocomposites, as a result of the anchoring of 3C–SiC on g-C₃N₄. Also we noticed the decrease of photoluminescence (PL) emission intensities in the PL spectra of 3C–SiC@g-C₃N₄ with respect to pure g-C₃N₄, which indicates the reduced photo-induced charge recombination by the presence of 3C–SiC content on g-C₃N₄ nanosheets. In the application side, PLAL synthesized 3C–SiC@g-C₃N₄ nanocomposites exhibited enhanced visible light driven photocatalytic degradation of methylene blue dye in water, improved antibacterial activity against Pseudomonas aeruginosa (gram-negative) and Staphylococcus aureus (gram-positive) bacteria, and also served as better inhibiting agent for biofilm formation, compared to pure g-C₃N₄ nanosheets. It is quite obvious from our studies that this ceramic-polymeric nanocomposite, 3C–SiC@g-C₃N₄ has the potential application for antibacterial and anti-biofilm activities in addition to its remarkable photocatalytic performance.
