Anisotropic magneli phase Ti-suboxides in β- cyclodextrin template - Enhanced charge separation upon gold doping Sarkar, Monojit Bhattacharya, Piyali Chatterjee, Hirak Sarkar, Sudeshna Mandal, Barun Biswas, Sudipta Ghosh, Sujit Kumar De, Swati Magneli phase Ti4O7 Au-doped Ti4O7 Substoichiometric titanium oxides i.e. Magneli phase (MP) TiOx are attractive due to their conductive nature. However, their synthesis is challenging. In this work, Anisotropic MP- Ti4O7 nanoparticles and Au doped nanocomposites were synthesized using β- cyclodextrin as template. The MP nanomaterials were 20-30 nm in size. The synthesis conditions were mild. These MP- TiOx nanomaterials show efficient charge separation upon light excitation i.e. they (i) act as efficient photocatalysts; (ii) they can be sensitized by a fluorescent dye; (iii) finite element method (FEM) simulations indicate substantial interfacial plasmonic charge generation at the metal-semiconductor interface in the doped nanocomposites. 2024-04-10T11:50:20Z 2024-04-10T11:50:20Z 2024 journal article Chemical Physics Impact 8 (2024) 100432 [10.1016/j.chphi.2023.100432] https://hdl.handle.net/10481/90620 10.1016/j.chphi.2023.100432 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
