Here, we present an innovative and creative sustainable technique for the fabrication of titania (TiO2) using Acorus calamus (A. calamus) leaf extract as a new biogenic source, as well as a capping and reducing agent. The optical, structural, morphological, surface, and thermal characteristics of biosynthesized nanoparticles were investigated using UV, FTIR, SEM, DLS, BET, and TGA-DSC analysis. The phase formation and presence of nanocrystalline TiO2 were revealed by the XRD pattern. FTIR analysis revealed conjugation, as well as the presence of Ti–O and O–H vibrational bands. The nanoparticles were noticed to be globular, with an average size of 15–40 nm, according to the morphological analysis, and the impact of size quantification was also investigated using DLS. The photocatalytic activity of bare, commercial P-25 and biosynthesized TiO2 (G-TiO2) nanoparticles in aqueous solution of rhodamine B (RhB) dye was investigated under visible light irradiation at different time intervals. The biosynthesized TiO2 nanoparticles exhibited strong photocatalytic activity, degrading 96.59% of the RhB dye. Different kinetic representations were utilized to analyze equilibrium details. The pseudo-first-order reaction was best suited with equilibrium rate constant (K1) and regression coefficients (R2) values 3.72 × 10−4 and 0.99, respectively. The antimicrobial efficacy of the prepared nanoparticles was investigated using the disc diffusion technique. Further, biosynthesized TiO2 showed excellent antimicrobial activity against the selected gram-positive staining (B. subtilis, S. aureus) over gram-negative (P. aeruginosa, E. coli) pathogenic bacteria in comparison to bare TiO2.

“…In application, water pollutants, such as herbicides, can also be effectively removed by using the photocatalyst based on CPs. Take the work by Sameer Ahmad et al as an example 38 . In this case, graphene-polyindole nanocomposites (Gr-PIn NC) were chosen as a cost-effective photo-catalyst to degrade the herbicide 2,4-Dichlorophenoxyacetic acid (2,4-D).…”

“…In the past few decades, several processes like coagulation, ion exchange, reverse osmosis, membrane separation process, flocculation, and photocatalysis − methods have been used for water purification, but each method has its own limitations. However, these water filtration techniques are expensive, produce secondary contaminants, need additional processing, use a lot of energy, and have low sequestration of the targeted contaminants over time.…”
