Special Issue Information

Dear Colleagues,

In this century, environmental issues have reached a critical juncture, demanding urgent attention and concerted global effort. Photocatalysis, utilizing light to drive chemical reactions, holds great potential in addressing environmental challenges. Various great works that focus on enhancing photocatalyst efficiency, expanding spectral response, clarifying the photodegradation process, etc., have emerged. This Special Issue seeks to explore and showcase the latest developments in photocatalysis for environmental applications, covering a spectrum of topics from the design and synthesis of novel photocatalytic materials to the fundamental understanding of reaction mechanisms and the translation of research into practical applications. We welcome submissions that delve into various facets of photocatalytic research for environmental applications, including, but not limited to, the following subtopics:

  • Design, synthesis, and characterization of novel photocatalytic materials for environmental applications.
  • Fundamental insight into photocatalytic mechanisms.
  • Computational modeling and simulation of photocatalytic systems.
  • Scaling up photocatalytic processes for industrial applications.
  • Reviews on photocatalysis in environmental applications.

One of the most challenging problems for people around the world is the lack of clean water. In the past few decades, the massive discharge of emerging organic pollutants (EOPs) into natural water bodies has exacerbated this crisis. Considerable research efforts have been devoted to removing these EOPs due to their biotoxicity at low concentrations. Heterogeneous photocatalysis via coupling clay minerals with nanostructured semiconductors has proven to be an economical, efficient, and environmentally friendly technology for the elimination of EOPs in drinking water and watershed water. Natural zeolite minerals (especially clinoptilolites) are regarded as appropriate supports for semiconductor-based photocatalysts due to their characteristics of having a low cost, environmental friendliness, easy availability, co-catalysis, etc. This review summarizes the latest research on clinoptilolites used as supports to prepare binary and ternary metal oxide or sulfide semiconductor-based hybrid photocatalysts. Various preparation methods of the composite photocatalysts and their degradation efficiencies for the target contaminants are introduced. It is found that the good catalytic activity of the composite photocatalyst could be attributed to the synergistic effect of combining the clinoptilolite adsorbent with the semiconductor catalyst in the heterogeneous system, which could endow the composites with an excellent adsorption capacity and produce more e/h+ pairs under suitable light irradiation. Finally, we highlight the serious threat of EOPs to the ecological environment and propose the current challenges and limitations, before putting the zeolite mineral composite photocatalysts into practice. The present work would provide a theoretical basis and scientific support for the application of zeolite-based photocatalysts for degrading EOPs. Full article
