Structure, Synthesis and Applications of TiO2-Based Nanomaterials

Dear Colleagues,

Functional titanium dioxide-based nanomaterials and nanocomposites are the subject of renewed contemporary interest towards diverse applications in the fields of energy materials, environmental remediation, and chemical engineering. While the promise of high-performance titanium dioxide photocatalysts has been decades in the pipeline, only in recent years has the scope and performance of applied TiO₂ systems undergone significant growth, motivating an in-depth examination of approaches to consolidate recent advances with an emphasis on effective materials design.

Driven by developments in predictive analysis, synthesis techniques, and system design, TiO₂ host structures are able to serve in diverse roles including photocatalysts, catalyst supports, and battery electrode materials, to name but a few.

Progress towards the implementation of TiO₂ encompasses five main areas: (1) The synthesis of TiO₂ nanostructures such as nanotubes, nanoflowers, nanospheres, and mesocrystals; (2) The fabrication of multi-scale heterostructures; (3) Functionalization with secondary phases including metal/metal oxide nanoparticles, graphene and carbon nanotubes; (4) The modification of TiO₂ lattices through cation and anion substitution and doping, and (5) design and fabrication of functional titania based systems towards specific applications.

For this Special Issue, we invite contributions from researchers working on applied TiO₂ materials across diverse fields. To create a multi-disciplinary perspective, the papers presented in this issue will show how developments from multiple aspects can be combined to impart high levels of functionality to TiO₂-based materials, with an emphasis on the design and processing of nanomaterials and nanocomposites.
