“…Water pollution is a critical environmental and public health concern. In addition to microbial pathogens, water sources are often contaminated with various pollutants, including organic dyes and chemical substances, leading to the risk of long-term environmental damage [1]. Nanomaterials have emerged as potential solutions to effectively tackle the issues associated with water disinfection and decolouration.…”

This work examined the synthesis, antibacterial activity, and decolourisation of WO3@Graphene nanorods (WO3@Gr NR). WO3@Gr NR nanocomposite was in situ produced via a facile one-step hydrothermal process employing sodium tungstate dihydrate and exfoliated graphene as precursors. The resulted NR exhibited an average diameter of 13 nm, a large specific surface area of 53.3 m2 g−1, and a bimodal pore size distribution with an average pore size of 5.5 nm. The optical bandgap is extrapolated to be 2.75 eV. Graphene was shown to be responsible for the sample’s elaborate visible-light absorption, which improved adsorption and the ability to harvest visible light. WO3@Gr NR are more efficient against E. coli than S. aureus, killing up to 52% and 39% of cells, respectively, after two hours of treatment. When used in conjunction with invisible light, the NR killed E. coli and S. aureus by 78 and 62%, respectively. The bactericidal activity of photoinduced WO3@Gr NR was evaluated against P. aerugunosa, E. faecalis, E. coli, and S. aureus. The photocatalytic constant rates of organic dye methylene blue (MB) were determined to be 0.01 min−1. An IC50 (50% cell growth inhibition) value of 97 (μg ml−1) was determined for the nanocomposite against human liver cancer cell lines (HepG2). Our findings suggest that this nanorod may be utilised to degrade bacteria and organic colours in wastewater simultaneously while posing no risk to human health.
