Special Issue "Titanium Dioxide Photocatalysis"
A special issue of Catalysts (ISSN 2073-4344).
Deadline for manuscript submissions: closed (15 July 2017)
Dating from the seminal work of Fujishima et al. issued in 1971, titanium dioxide (TiO2) is at the center of intense research devoted to the development of efficient photocatalysts. Among the many candidates for photocatalytic applications, TiO2 is almost the only material suitable for industrial use. This is because TiO2 shows a good trade-off between efficient photoactivity, high stability, and low cost.
The principal applications deal with the use of TiO2 as photocatalyst for environmental remediation both in polluted air and waste water treatment and as a material in solar cells.
The rational design elements of interests for efficient TiO2 catalysts for this Special Issue are optical properties, nanocrystal shape and organization in superstructures.
The main drawback of TiO2 photocatalysts still remains their inability in visible light absorption and photoconversion, and most part of recent research activities are devoted to the improvement of the optical absorption properties of TiO2 nanomaterials. Strategies including doping; self-doping; realization of composites with plasmonic materials, with 2D materials, with other semiconductors, and with quantum dots are of particular interest. Black-TiO2 visible light active photocatalysts, antimicrobial materials, photoelectrochemical devices for water splitting and CO2 photo-reduction, are among the hot topics.
On the other hand, precise crystal shape (and homogeneous size) and organization in superstructure from ultrathin films to hierarchical nanostructures have been demonstrated to be critical for obtaining photocatalyst with high efficiency and selectivity. This topic is another pillar for the present Special Issue on “Titanium Dioxide Photocatalysis”, and submission on it are recommended.
The present Special Issue of Catalysts is aimed at presenting the current state-of-the-art in the use of TiO2 as photocatalyst, with a special emphasis on new TiO2 nanomaterials (both powdered catalysts and photoelectrodes) for photocatalytic water splitting, CO2 reduction and environmental remediation. In the present Special Issue, we have invited contributions from leading groups in the field with the aim of giving a balanced view of the current state-of-the-art in this discipline.
