Special Issue Information

Dear Colleagues,

Climate change has forced the scientific community to explore new alternative methods of mitigating environmental problems. One method of solving these issues is heterogeneous photocatalysis. This technology has been met with success in terms of reducing CO2 molecule into solar fuels, splitting water molecules to generate H2 and O2, removing air pollutants, etc. However, the design and development of new catalytic materials is an important issue that must be solved.

We are pleased to invite you to submit your research related to the promising new catalytic materials for energy and environmental applications. This Special Issue will serve as an advanced forum to discuss and interface different approaches for the synthesis and development of new catalytic materials.

This Special Issue will provide a guide of frontier knowledge generated to enable the scientific community to develop new ideas and concepts to facilitate the design of catalytic materials with better efficiencies to generate clean and renewable energy and to provide strategies to remove different pollutants from the natural sources, e.g., air, water, and soil.

In this Special Issue, both original research articles and reviews are welcome. Research areas may include (but not limited to) the following: synthesis of new catalytic materials, optimization of photocatalytic reactors, CO2 reduction, H2 production, O2 evolution, degradation of organic molecules, e.g., dyes, antibiotics, plastics, etc.

We look forward to receiving your contributions.

Photochemical and photocatalytic oxidation of naproxen (NPX) with UV-A light and commercial TiO2 under constant flow of oxygen have been investigated. Adsorption experiments indicated that 90% of the solute remained in the solution. Combined chemical analysis of samples on the photochemical degradation indicated that NPX in an aqueous solution (20 ppm) is efficiently transformed into other species but only 18% of the reactant is mineralized into CO2 and water after three hours of reaction. Performing the photocatalytic oxidation in the presence of TiO2, more than 80% of the organic compounds are mineralized by reactive oxidation species (ROS) within four hours of reaction. Analysis of reaction mixtures by a combination of analytical techniques indicated that naproxen is transformed into several aromatic naphthalene derivatives. These latter compounds are eventually transformed into polyhydroxylated aromatic compounds that are strongly adsorbed onto the TiO2 surface and are quickly oxidized into low-molecular-weight acids by an electron transfer mechanism. Based on this and previous studies on NPX photocatalytic oxidation, a unified and complete degradation mechanism is presented. Full article
