Special Issue Information

Dear Colleagues,

Photocatalysis is a highly attracting process with multiple applications, especially in the field of pollution removal and fuel production. The major global issues today are those concerned with the treatment of wastewater from various industries, and also a guaranteed supply of clean energy. For these reasons, study and investigations on advanced multifunctional materials for water purification, at low cost and with less energy, and advanced photocatalytic materials for the production of clean energy by photocatalytic and photoelectrocatalytic water splitting.

The aim of this special issue focuses on their novel photocatalytic materials synthesis, properties and discussions on their fundamental principles and application achievements in energy fields. The following topics are emphasis:

  1. Morphology dependent and facet-designed photocatalytic materials
  2. Surface modification and doping of photocatalytic materials
  3. Novel and green synthesis of photocatalytic materials
  4. Photocatalytic Wastewater treatment and environmental remediation
  5. Photocatalytic hydrogen/oxygen evolution and water splitting
  6. Photocatalytic CO2 reduction
  7. Photoelectrochemistry of photocatalytic materials

This special issue will highlight and attract world-leading researcher in the area of photocatalysts for energy and environmental research by publishing high quality, original contributions in these application areas.

Visible-light photocatalytically active titanium oxide (TiO2) nano-powder was synthesized by a flat-flame chemical vapor condensation method. The formation of TiO2 consisting of different ratios of anatase and rutile phases was controlled by two parameters: the acetylene flow rate (C2H2, 600 sccm and 800 sccm) and the acetylene/oxygen flow ratio (C2H2/O2, 1:3, 1:4, 1:5, and 1:6). The location of the photonic center was identified for visible-light absorption, which is in the anatase grains. The photonic center on the surface of anatase grains happens to be the nucleation site for rutile in an oxygen-deficient environment. The visible-light absorption could be attributed to the formation of defect levels related to the photonic center within the band gap of anatase. The major role of the mixed-phase structure of TiO2 in the enhancement of visible-light photocatalytic activity is in the enhancement of carrier separation and not of light harvest, for the powder produced in this study.
