Special Issue Information

Dear Colleagues,

This Special Issue focuses on recent developments in catalytic materials, including photocatalysts, piezocatalysts, and tribocatalysts, which are a promising class of functional materials for environmental remediation and energy conversion applications.

Photocatalysts, piezocatalysts, and tribocatalysts have demonstrated superior performance in various catalytic applications such as water splitting, CO2 reduction, and wastewater treatment by degrading organic pollutants under visible light irradiation and mechanical energy. The unique electronic and structural properties of catalysts, as well as their surface modification capabilities, make them a versatile platform for designing efficient and selective catalysts.

This Special Issue aims to provide a comprehensive overview of recent advances in photocatalysts, piezocatalysts, and tribocatalysts, including their synthesis, characterization, and catalytic applications. We welcome contributions related to topics such as the following:

  • Photocatalysts, piezocatalysts, and tribocatalysts for water splitting and CO2 reduction;
  • Photocatalysts, piezocatalysts, and tribocatalysts for wastewater treatment;
  • Surface modification of catalysts for enhanced catalytic performance;
  • Theoretical studies on the electronic and optical properties of catalysts;
  • Composites for improved catalytic performance.

We hope that this Special Issue will stimulate further research in the field of photocatalysis, piezocatalysis, and tribocatalysis and promote their practical applications in environmental and energy-related areas.

The electrochemical reduction of carbon dioxide (CO2) at room temperature into industrial chemicals and energy products offers a promising strategy to mitigate atmospheric greenhouse gas emissions. In this study, bismuthene was employed as a catalyst for CO2 reduction reaction (CO2RR). Through first-principles calculations, we evaluated the CO2RR catalytic activities of bismuth (Bi) on the (001) and (012) surfaces, analyzing the mechanisms underlying these activities. Surface energy calculations for monolayer and multilayer bismuthene confirmed that monolayer bismuthene is stable and suitable for catalytic applications. Adsorption free energies of intermediates showed that formic acid is the primary product. Furthermore, it is found that the Bi(012) surface has a lower free energy barrier than Bi(001) in the CO2RR process, representing the higher catalytic activity. These results provide theoretical insights for designing bismuthene-based CO2RR catalysts with reduced overpotential, improved efficiency and enhanced selectivity, particularly enhancing catalyst selectivity.

The immobilization of suspension catalysts in flexible, fibrillated films offers a promising solution to the mass transfer limitations often encountered in three-phase hydrogenation reactions. This study investigates the catalytic performance and mass transfer properties of fibrillated films in the hydrogenation of nitrobenzene to aniline, comparing them to free-flowing powdered catalysts. Fibrillated films were prepared from Pd/C catalysts with varying thicknesses (100–400 µm), and their performance was evaluated through kinetic studies in both batch reactors and microreactors. The specific activity of the films was significantly influenced by film thickness with thinner films demonstrating lower mass transfer limitations. However, mass transfer limitations were observed in thicker films, prompting the development of alternative film designs, including enhanced macro-porous films and sandwich structures. These modifications successfully minimized diffusion limitations, achieving similar specific activity to the powder catalysts while maintaining the mechanical stability of the films. This work demonstrates the feasibility of using fibrillated films for continuous catalytic processes and highlights their potential for efficient catalyst reuse, avoiding filtration steps and enhancing process sustainability. Furthermore, while PTFE remains indispensable for producing such films due to its mechanical and thermal stability, ongoing research focuses on identifying more environmentally friendly alternatives without compromising performance.
