Metallic Ti₃O₅ hierarchical porous microspheres with an enhanced photothermal property

Abstract

Metallic γ-Ti3O5 hierarchical porous microspheres with strong localized surface plasmon resonance are reported, which can inhibit cancer cell viability in vitro and disrupt tumor tissue growth in vivo under the irradiation of near infrared light.

Fundamentals and applications of photo-thermal catalysis

“…Examples of this type of structures are non-stoichiometric materials with oxygen/metal vacancies, mixed metal valences and/or conduction electrons. 30,[293][294][295] An appealing precedent of this approach was recently reported by Ozin and co-workers in the photo-thermal hydrogenation of CO 2 using the non-stoichiometric black In 2 O 3Àx /In 2 O 3 catalyst. 46 The authors found that the hydrogenation of pale yellow In 2 O 3 at different temperatures led to the generation of black nonstoichiometric heterostructures composed of In 2 O 3Àx domains in crystalline stoichiometric In 2 O 3 .…”

Black TiOx Films with Photothermal-Assisted Photocatalytic Activity Prepared by Reactive Sputtering

“…Both Ti 2 O 3 and Ti 3 O 5 have been reported for their high-performance photothermal conversion [ 9 , 31 ]. The increase in surface temperature shows a significant positive correlation with the content of Ti 2 O 3 and Ti 3 O 5 phases in black films.…”

Harvesting Light To Produce Heat: Photothermal Nanoparticles for Technological Applications and Biomedical Devices

“…[ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ] The same light to heat conversion mechanism holds in different nanomaterials featuring LSPRs. This is the case of semiconductor nanocrystals with appreciable free carriers concentration, like Cu chalcogenides,[ 82 , 83 , 84 , 85 ] zinc oxide, [86] ITO (indium tin oxide), [87] nonstoichiometric titanium oxides [88] or molybdenum [89] oxides. In these NP the LSPR band maximum can be tuned (usually in the NIR region) by tuning the doping degree and/or the stoichiometry.…”
