Application of green synthesized biogenic Nd2Zr2O7 supported on dendritic fibrous nano-titanium for photocatalytic and antibacterial activities

Abstract

The combination of a phase junction and fibrous structure has been proven to improve the catalytic ability and performance, as well as the separation of nano titanium oxide. However, there is still a pressing need for facile and environmentally sustainable fabrication techniques. In this research, we introduce an innovative approach for the fabrication of dandelion-like TiO2 with anatase/TiO2 phase interfaces and an extremely specific exterior layer using a user-friendly and green deep eutectic solvent-tuning method. We have successfully synthesized DaNd2Zr2O7 nanospheres on dendritic fibrous nanotitanium (DFNT@DaNd2Zr2O7) using a straightforward method. The DFNT@DaNd2Zr2O7 composite retained its mesoporous structure and crystalline morphology, despite the loading of DaNd2Zr2O7. These nanocomposites are employed as active photocatalysts under UV radiation and can effectively treat water contaminated with organic pollutants and microorganisms. Additionally, they exhibit antimicrobial properties against gram-positive species like pathogenic strains of Enterococcus faecalis and Staphylococcus aureus, as well as Gram-negative species like Escherichia coli, Furthermore and Klebsiella pneumonia, these nanocomposites exhibit excellent stability over ten cycles, reinforcing their potential as proficient catalysts to address environmental concerns.
