Modified hybrid functionals, particularly the PBE0 functional with 11.4% fraction of exact exchange, are shown to provide highly accurate atomic structures and also accurate electronic structure data, including optical excitation energies. With $\\rm{DFT+U}$, accurate optical spectra are also possible, but only if the Hubbard U is applied on the O $\\rm2p$ electrons exclusively. Furthermore, both methods, the 11.4%-PBE0 hybrid functional and the $\\rm{DFT+U_p}$ scheme have been used to study TiO$\\rm{_2}$ amorphous ultra-thin films, confirming the agreement of the two methods even with respect to small details of the optical spectra.

The cluster adsorption is found to be dominated by van der Waals forces. The electronic structure and in particular the excitation energies of the bare clusters and the TiO2/graphene composites are found to vary largely in dependence on the size of the respective constituents. This holds in particular for the energy and the spatial localization of the highest occupied and lowest unoccupied molecular orbitals. In addition to a substantial gap narrowing, a pronounced separation of photoexcited electrons and holes is predicted in some instances. This is expected to prolong the lifetime of photoexcited carriers. Altogether, TiO2/graphene composites are predicted to be promising photocatalysts with improved electronic and photocatalytic properties compared to bulk TiO2."}],"status":"public","publisher":"Willey","date_updated":"2023-04-21T09:47:30Z","oa":"1","author":[{"orcid":"0000-0002-8481-4161","last_name":"Badalov","id":"78800","full_name":"Badalov, Sabuhi","first_name":"Sabuhi"},{"first_name":"René","full_name":"Wilhelm, René","last_name":"Wilhelm"},{"id":"468","full_name":"Schmidt, Wolf Gero","last_name":"Schmidt","orcid":"0000-0002-2717-5076","first_name":"Wolf Gero"}],"date_created":"2020-09-09T09:16:17Z","title":"Photocatalytic properties of            graphene‐supported            titania clusters from            density‐functional            theory","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/10.1002/jcc.26363","open_access":"1"}],"doi":"10.1002/jcc.26363","publication_status":"published","publication_identifier":{"issn":["0192-8651","1096-987X"]},"related_material":{"link":[{"url":"https://onlinelibrary.wiley.com/action/downloadSupplement?doi=10.1002%2Fjcc.26363&file=jcc26363-sup-0002-Supinfo.pdf","relation":"supplementary_material"}]},"year":"2020","citation":{"short":"S.
