Special Issue Information

Dear Colleagues,

Photocatalytic processes have shown great potential as a low-cost, green-chemical, and sustainable technology able to address energy and environmental issues. Nanosized materials, with their superior features, including structural, optical, as well as size-tunable electronic properties, can endow remarkable catalytic performance and even novel functionalities. This has expanded the photocatalysis frontier from H2 production and environmental remediation toward novel applications such as photoelectric sensing and photodynamic therapy. Notably, comprehension of processing–structure–property relationships in functional photoactive nanomaterials has been unveiling mechanistic pathways underlying the photocatalytic process. Understanding the nanoscale will drive design and synthesis strategy to tailor photocatalytic and/or optical properties of nanostructured materials, including coupled, capped, sensitized, and organic–inorganic nanocomposite semiconductor systems.

This Special Issue aims to present recent advances in any aspect of nanomaterials in photocatalysis. It collects original research papers, reviews, and commentaries focused on synthesis methods; surface, microstructural, optical, and magnetic features properties; as well as computational studies and reaction mechanisms of nanostructured materials for photocatalytic applications to bring forward the next generation of photocatalytic systems.

Submissions are welcome especially (but not exclusively) in the following areas:

  • Nanomaterials design and synthesis;
  • Photocatalytic activity;
  • Surface and microstructural properties;
  • Reaction mechanisms;
  • Environmental remediation;
  • Processing–structure–property relationships.

Title: Spherical mesoporous carbon/titanium dioxide hybrid photocatalyst with enhanced photoactivity under UV and solar light irradiation
Abstract: Present study reports a facile sol-gel approach enabling to obtain spherical ordered mesoporous carbon/titanium dioxide hybrid photocatalysts. The content of TiO2 in hybrids was easily controlled through the introduction of the purification step to the synthesis route. The active surface area of hybrid was highly enhanced via homogeneous TiO2 nanoparticles distribution on carbon support. The synergistic effect between hybrid components successfully improved the charge carrier generation and its proper separation. The obtained hybrids exhibited superior photocatalytic performance in Rhodamine B decomposition under UV light irradiation. Moreover, addition of carbon into composite resulted in enhanced absorption in vis region and thus the catalyst with the highest amount of metal oxide displayed also enhanced photocatalytic activity in organic dye degradation under solar light illumination. The photocatalytic activity of the hybrid composed of 36 % TiO2 was over 4 and 3.25 times higher for UV light and nearly 2 and 2.5-times higher for solar light irradiation in comparison to the reference P25 and T600, respectively. Here, it was proved that formation of stable titanium dioxide-carbon spheres heterojunction allows to create efficient and low cost photocatalyst, which is active both in visible and ultraviolet light irradiation.
Keywords: mesoporous carbons, titanium dioxide, hybrid photocatalysts, photocatalysis
