Special Issue Information

Dear Colleagues,

The most traditional inorganic semiconducting photocatalysts such as TiO2 and ZnO function only under UV light irradiation, therefore, visible light-responsive inorganic semiconducting photocatalysts such as BiVO4 and Ta3N5 have recently been investigated.  On the other hand, organic semiconducting materials such as graphitic carbon nitride (g-C3N4) nanomaterials have also been developed as highly efficient photocatalysts which can operate even under visible light irradiation.

Further research into the development of such inorganic and organic visible light-responsive photocatalytic materials will be vital in establishing artificial photosynthetic systems to efficiently convert solar energy into useful chemical or electrical energy, thus ensuring a stable and cleaner energy source for future generations.  We feel it would be beneficial at this time to publish the most recent works in these fields in a special issue with a collection of curated and interesting articles related to the photocatalytic performance of both inorganic and organic semiconducting materials.  

We would like to invite you to contribute an article, either an original research article or review, to this Special Issue of Crystals.  The deadline for submission is December 15th, 2021. If you should accept our invitation, please refer to the website at the top for more details regarding your submission. We look forward to hearing from you.

Thank you for your kind attention and time.

The potential of photocatalysts modified cement-based materials in degrading environmental pollutants is evident in previous studies, but the application of photocatalytic cement-based materials still appears limited in actual practice due to the dispersion effect. This work seeks to prepare photocatalytic cement paste by mixing cement with BiOBr precursor solutions in terms of the improvement of dispersion efficiency, and additional hydrothermal conditions provided by autoclaved curing period are required to activate the photocatalytic activity of photocatalysts crystals. The presence of BiOBr precursor solutions results in an increase of RhB degradation rate of up to 45.4% and the NOx removal efficiency was up to 4.4%, and the formation of BiOBr photocatalysts crystals is the main reason for photocatalytic performance enhancement. The morphology of photocatalysts and the pore size distribution of cement paste also contribute to the photocatalytic activity enhancement by the exposed surface of photocatalysts, which are supported by the analyses of Scanning Electron Microscope and Mercury Intrusion Porosimetry results. A new mechanism is suggested to explain the synergistic role of crystals and microstructure on the enhancement of photocatalytic activity with the extension of autoclaved curing time. As supports for photocatalysts, the development changes of compressive strength of cement paste are also discussed. Full article
