In this study, we presents a novel method for bolstering the photocatalytic effectiveness of crystalline titanium dioxide (TiO2) through integration graphitic carbon nitride (g-C3N4), creating series TiO2/g-C3N4 nanohybrids (TiCN-NHs). Leveraging an economical and scalable pyrolysis technique, crafted different ratios these (TiCN-NHs-1, TiCN-NHs-2, TiCN-NHs-3, TiCN-NHs-4) to optimize their performance in harnessing visible light photocatalysis. Detailed spectroscopic examinations were performed dissect nanohybrids' structural morphological nuances, alongside chemical interactions states. The primary evaluation prowess was degradation selected colored organic contaminant under exposure. TiCN-NHs showcased unprecedented efficiency, surpassing that p-TiO2 bulk b-g-C3N4 by twelvefold eightfold, respectively, comparable conditions. This dramatic increase activity is credited harmonious interface between TiO2 g-C3N4 within nanohybrids, fostering diminished bandgap promoting efficient charge separation. Additionally, photoluminescence density state analyses, specifically focusing on valence band spectra irradiation, further confirmed findings. synergistic effects observed not only enhance rates but also spotlight potential solar energy conversion environmental cleanup applications, offering promising avenue future research sustainable technologies.

A functionalized chitosan thiourea composite (CH-TU) was successfully synthesized using formaldehyde as a crosslinking agent for enhancing silver recovery from different aqueous solutions. Comparison sorption studies with non-functionalized (CH-F) reference material were conducted. Grafting led to an improvement in the performances, i.e., 0.763 mmol Ag g−1 CH-F vs. 2.125 CH-TU. The pseudo-first-order rate equation (PFORE) fitted kinetics at saturation times of 40 and 30 min CH-TU, respectively, while isotherms Langmuir Sips equations both sorbents. Fourier transform infrared (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), nitrogen sorption–desorption (BET-surface area), elemental analysis, thermogravimetric (TGA) pH zero charge (pHpzc) used characterize investigate mechanism. Sorption performed three check reproducibility, performances stable over 20 cycles, limited decrease performance (5 3% respectively). Nitric acid solution (0.3 M) efficient desorbing adsorbed metal ions. grafted sorbent is considered promising tool recovering Ag(I) acidic waste leachate derived spent films.
