Special Issue Information

Dear Colleagues,

Oxide-based photocatalysts have become a viable technology in various fields of application, such as photovoltaics, artificial photosynthesis and water splitting, hydrogen photoproduction, CO2 reduction, organic synthesis, chemical sensors, and photodegradation of air pollutants. The fields of application shown are very broad, and the study of new oxide-based materials in combination with organic compounds and/or metal nanoparticles is widely studied. After the historical discovery of Fujishima and Honda, much of the work was performed by taking the metal oxide system based on d0 and d10, and TiO2 is the most widely used oxide in the photocatalytic application, but other oxides can be used (ZnO, Fe2O3, Ta2O3, CuO, NiO, Cr2O3, RuO2, etc.). However, depending on the oxide-based material of the field of application, the different crystalline shape and composition can drastically modify the properties (band gap, active surface area, stability). In recent years, various specific aspects of oxide-based photocatalysis have been investigated. The purpose of this Special Issue in “Advanced Oxide-Based Materials for Photocatalytic Applications” is to show the current state-of-the-art in the synthesis, functionalization, characterization, and application of oxide-based materials in photocatalysis.

The Special Issue will cover but not be limited to the following topics:

  • Preparation of oxide-based and hybrid materials for photocatalytic application;
  • Use of oxide-based material as active support for metal nanoparticles and/or organic sensitizers;
  • Physical, chemical, and electrochemical characterization of oxide-based materials;
  • Applications of oxide-based materials on photocatalytic hydrogen production;
  • Applications of oxide-based materials on photocatalytic CO2 valorization;
  • Applications of oxide-based materials on photocatalytic organic reaction;
  • Applications of oxide-based materials for chemical sensors;
  • Application in environmental protection as photocatalysts on harmful inorganic and/or organic pollutants.

Nanocomposite materials were prepared by compounding polypropylene (PP) with zinc oxide (ZnO) nanoparticles, using a twin-screw extruder. The compound was molded by injection molding to form dumbbell-shaped specimens. The influence of ZnO nanoparticle content on the morphology, mechanical properties, chemical structure, photocatalytic activity, and antibacterial properties of the obtained nanocomposites was investigated. The morphological images showed that the ZnO nanoparticles were well distributed in the PP matrix. Characterizations of the mechanical properties and chemical structures before and after sunlight exposure found that at the shortest exposure time, crosslinks could occur in the nanocomposites, which resulted in improved mechanical properties. However, sunlight exposure with the time period longer than 18 weeks caused the reduction of the mechanical properties, due to degradation of the PP matrix. It was found that PP with 2% ZnO could achieve the photocatalytic degradation of methylene blue up to 59%. Moreover, the result of antibacterial tests indicated that the nanocomposites had better antibacterial properties than neat PP. Full article
