Special Issues and Collections in MDPI journals
The “Photocatalytic Nanomaterials for Pollutant Remediation” Special Issue aims to collect articles regarding the preparation of new photocatalysts as powders or thin films (bare and loaded semiconductors or materials obtained by coupling different semiconductors) for the abatement of pollutants present both in gas-phase and in aqueous solutions. Research concerning the modelling and development of new photoreactors, including solar photoreactors, for pollutants remediation will be also considered for publication. Articles concerning the degradation of emergent micro- or nano-pollutants, like drugs or PFAS, will be particularly welcome; on the contrary, articles reporting the degradation of dyes, even for testing new materials, will be not considered.

Title: Photocatalytic activity of core-shell nanoparticles [email protected], prepared by reactive deposition in aerosol micro droplets
Authors: Dvorsky, Richard
Affiliation: VSB – Technical University of Ostrava, Ostrava, Czech Republic
Abstract: A very important problem of current nanotechnology is the practical handling of powder photocatalytic materials. When the size of nanoparticles is in the order of tens nm, their extraction from the liquid dispersion to a state of a dry powder is highly problematic. The thickening and subsequent drying of the dispersion leads to significant agglomeration and larger particles are formed. As a result of the exciton recombination, the internal volume of the particles contributes to the photocatalytic process significantly less than their external surface area. The aim of this work is the application of a new patented technology of "aerosol microreactors", which enables preparation of photocatalytic core-shell nanostructure on carrier particles of inactive material. The "aerosol microreactors" method allows controlled deposition of the photocatalytic coating of the desired thickness onto carrier particles dispersed in the microdroplets of a single reactant solution. These microreactors are generated in an ultrasonic nebulizer in the order of micron dimensions. To test the function of the "aerosol microreactors" method, a [email protected] core-shell photocatalytic nanoparticle powder was prepared on Si carrier particles resulting from the disintegration of semiconductor silicon in a Water Jet Mill. The experiment confirmed a very good match between the required and the real thickness of the semiconductor shell. In contrast to the ZnS nanoparticle liquid dispersion that is difficult to handle, the new method allowed the preparation of dry photocatalytic nanopowder. The new powdered material has shown good photocatalytic efficiency in both the liquid environment in phenol degradation and the gaseous environment in N2O degradation.
