Special Issue Information

Dear Colleagues,

This Special Issue focuses on current research activities on the topic of new advanced material design to catalyze the decomposition of micropollutants. A wide variety of novel advanced materials has attracted particular interest in this field, mainly due to their high photocatalytic efficiency in converting pollutants into environmentally friendly byproducts. In such cases, there is a broad acceptance that computational tools are critically important for developing such materials and can help rationalize the new nanoscale phenomena. Fundamental mechanistic studies based on the synergy between theory and practice can guide the discovery/development of new catalytic materials.

Therefore, we invite authors to contribute high-quality, original research articles, reviews, as well as opinion letters by experts in the field, focusing on the preparation, modification, and application of novel catalytic materials design that will be considered for this Special issue. Potential topics include, but are not limited to:

  • Advances in material synthesis and bandgap engineering;
  • Nanomaterials for energy and catalytic purposes;
  • Advanced materials characterization techniques;
  • Computational materials characterization and computing tools;
  • Artificial photosynthesis;
  • Photocatalysis.

Recently, the production of new photocatalytic materials has attracted considerable attention as a promising strategy to mitigate anthropogenic environmental degradation. In this study, cement paste composites (water/cement ratio = 0.5) were prepared using a coating based on nanoparticles of SnO2 (SnO2/cement paste) and SnO2 decorated with Ag2O (Ag2O-decorated SnO2/cement paste) for photocatalytic applications. These coatings were prepared in this study by using the hydrothermal method as the strategy. Thus, photocatalyst efficiency was evaluated through the degradation of methylene blue (MB) and methyl red (MR) as cationic and anionic dyes, respectively, and the simultaneous degradation of MB/MR (1:1 v/v) dyes. Moreover, the photocatalytic mechanism was investigated in the presence of scavengers. Notably, an increase in pH in the range of 2–6 resulted in selective degradation of the MB/MR dye mixtures. Overall, the photocatalytic performance of these materials provides a novel platform technology focused on advanced civil engineering applications, which consequently facilitates the mitigation of various environmental problems.
