Heterolayered photocatalyst thin films of stratified TiO₂-WO₃ are developed by sequential depositions of titanate nanosheets (titanate-NS) and tungsten oxide (WO₃). The electrophoretic deposition method is used for the deposition of exfoliated titanate-NS, and modified chemical solution deposition (MCSD) is used for the deposition of WO₃. The TiO₂-WO₃ heterolayered thin films displayed randomly interconnected WO₃ nanoplate network grown on parallelly stratified titanate-NS. The TiO₂-WO₃ heterolayered thin films display high visible-light absorption with quenched photoluminescence signal, characteristic of visible-light harvesting capability with effective electronic coupling between titanate-NS and WO₃. The TiO₂-WO₃ heterolayered thin films show superior visible-light-driven photocatalytic degradation of tetracycline hydrochloride (TC) antibiotic. The resultant heterolayered thin films photodegrade 86 % of TC in 150 min. These photocatalytic performances surpass the bare WO₃ films under the same conditions. This finding demonstrates that the TiO₂-WO₃ heterolayered thin films are efficient visible-light-active photocatalysts for the degradation of antibiotics.

Within this piece of research, the detection capability of a carbon nitride nanosheet (referred to as C₃N₃NS) was investigated for the accurate identification of C₂H₄ and C₂H₂ through the implementation of a DFT methodology. The interaction energies of the most stable structures of C₂H₂ and C₂H₄ over C₃N₃NS were calculated at about −53.46 and – 21.92 kJ mol⁻¹, respectively. Based on the analysis of interaction energies, C₂H₂ formed a strong bond with C₃N₃NS, while C₂H₄ was adsorbed onto the C₃N₃NS through weak van der Waals forces. The complexation of C₂H₂ and C₂H₄ with C₃N₃NS was thoroughly examined using non-covalent interactions (NCIs), frontier molecular orbitals (FMOs), and natural bond orbital charge transfer (QNBOs). Significant differences in bandgap energy were observed in the FMO analysis for C₂H₂ with C₃N₃NS, ranging from 3.59 to 2.37 eV, highlighting the presence of strong non-covalent interactions (NCIs). Furthermore, the presence of non-covalent bonds between complexes was verified through the non-covalent interactions-low density gradient (NCI-RDG) analyses.

Tungsten-coated biochar samples were prepared using the innovative magnetron sputtering technique, varying power from 100 to 200 W and deposition time from 10 to 40 min. Various characterization techniques confirmed these samples' surface modifications and adsorptive potential for copper Cu(II) and methylene blue (MB). The power and deposition time influenced the tungsten coating percentage on the biochar, the adsorbent's features, and its adsorption potential. Higher power and longer deposition times increased the tungsten percentage on the biochar surface but reduced the material's adsorption potential. The best adsorption results were achieved with the BW₂ sample (150 W power and 20 min). Kinetic studies indicated that the pseudo-first-order and pseudo-second-order models fit well with the Cu (II) and MB adsorption curves, respectively. The Freundlich isotherm model best described the adsorption process, confirming the heterogeneous nature of the adsorbent surface. The adsorption of MB was more efficient at pH 6 (96 %) and pH 8 (94 %), decreasing in a basic medium (pH 10) due to electrostatic repulsion. For Cu (II), the best result was observed at pH 6 (48 %), associated with lower competition with H⁺ and greater stability of hydroxylated species. The controlled deposition of tungsten on the biochar surface via magnetron sputtering is a promising approach to enhancing its adsorption potential.
