Synchronously achieved surface Bi0 metallisation and incorporation of Bi3+/5+ ions into a W6+, N3− doped TiO2 lattice by the hydrothermal-reduction method: surface plasmonic resonance effect for efficient photocatalysis

Abstract: Vectorial charge transfer mechanisms in a bicrystalline framework of Bi0 surface deposited Bi3+/5+, W6+ and N3− doped TiO2 under solar light irradiation.

“…3a. The O-Ti-O and Ti-O stretching vibrations were observed for WNT, Cur-WNT and K 3 Cur-WNT samples at 731 and 424 cm -1 , respectively [15]. The IR spectra of curcumin molecule shows multiple peaks at 1501 (C=O/aromatic C=C stretching), 3509 (O-H stretching), 1620 (aliphatic C=C stretching), 1424 (=C-H bending vibration), 1590 (benzene ring stretching) and 1270 cm -1 (bending vibration of C-O in ether moiety) [22][23][24].…”

“…This precipitate was washed several times with distilled water to completely remove the chloride ions. Calculated amounts of sodium tungstate (0.002 g to obtain 0.02 atom % of W) and urea (0.0032 g to obtain 0.2 atom % of N) were dissolved in 50 mL of water and this solution was added dropwise using a separating funnel to the prepared titanium hydroxide gel with continuous stirring for 1 h. The obtained precipitate was dried at 110°C for 24 h and was further annealed at 500°C to obtain WNT sample [15]. 1 g of WNT sample was suspended in the curcumin solution (10 μM)/curcumin solution (10 μM) along with K 2 CO 3 solution (15 μM) for the preparation of Cur-WNT and K 3 Cur-WNT samples respectively for 10 h. This mixture was air dried to obtain Cur-WNT and K 3 Cur-WNT samples.…”
