Special Issue Information

Dear Colleagues,

Visible-light-mediated photocatalysis has garnered significant attention over the past few decades due to its potential to address pressing globle environmental and energy challenges. Photocatalysts, as the core in photocatalysis process, facilitate chemical reactions by absorbing photons and converting their energy for various applications. These materials have demonstrated their capability in solar energy conversion, water splitting for hydrogen production, pollutant degradation, air purification and organic synthesis, among others.

This Special Issue aims to bring together leading researchers to share their latest findings, insights and advancements. By highlighting novel synthesis techniques, mechanistic studies and innovative applications, this Special Issue seeks to provide a comprehensive overview of the current state of the field and stimulate future research directions. Contributions to this Special Issue will address the challenges, explore new frontiers and highlight the transformative potential of photocatalysis in solving global energy and environmental problems.

The topics of interest include, but are not limited to, the following:

  • Novel synthesis methods for photocatalysts;
  • Nanostructured and hybrid photocatalysts;
  • Advanced spectroscopic and computational methods for eluciding photocatalytic mechanism;
  • Charge separation and transfer dynamics in photocatalysis;
  • Photocatalysis in energy conversion and storage.

The conversion of nitrogen (N2) and water (H2O) into NH3 by photocatalysis under ambient conditions has been considered an environmentally friendly strategy. However, developing effective catalysts for N2 fixation is still challenging. Herein, we report a bimetallic JH Fe, Co/TiO2 derived from NH2-MIL-125(Ti) by the fast Joule heating (FJH) method for visible–light–driven catalytic N2 fixation. It was found that the photocatalytic N2 reduction efficiency of bimetallic FC@TiO2-JH was improved, enabling an NH3 yield rate of 110.14 µmol g−1 h−1 without any sacrificial agents. Furthermore, the rate was higher than those of Fe@TiO2-JH and Co@TiO2-JH, suggesting that the synergistic effect between Fe and Co broke the electronic equilibrium and increased the center of its d-band, enhancing electronic feedback to the antibonding π* orbitals of N2 while weakening the bonding energy of N≡N. Meanwhile, the rate was about 2.75 times higher than that of FC@TiO2-TF, which was calcined in a tube furnace. It is assumed that FJH might lead to the formation of lattice defects, leading to localized charge deficiency, enhanced carrier separation, and transport. Thus, doping of Fe and Co synergistically interacted with the defects produced from FJH, facilitating the photocatalytic reduction process. As detected, it had a greater ability to separate hole–electron pairs and transferred electrons to adsorbed N2 at faster rates. Our work demonstrates a prospective strategy for designing bimetallic catalysts derived from NH2-MIL-125(Ti) for N2 fixation. Full article
