Special Issue Information

Dear Colleagues,

In recent years, carbon-based catalysts (such as carbon nitride) have been regarded as very useful metal catalysts due to their unique physical and chemical properties. In fact, when carbon materials (such as graphene, carbon nanotubes, carbon dots, MOFs, COFs, and Mxene) form composite catalysts with other metals, the kinetic process of the catalytic reaction can be further improved due to the large specific surface of and the good conductivity of the carbon materials. Therefore, carbon-based catalysts have become a research hotspot in various fields. However, some carbon-based catalysts have disadvantages, such as being complicated to process, not environmentally friendly, and with a low yield. In addition, although carbon-based catalysts have been widely studied in water and wastewater treatment, the application cost and efficiency still need to be further improved. Therefore, in order to broaden the application of carbon-based catalysts in water purification, it is necessary to further optimize the preparation method and explore its removal mechanism of pollutants in water to obtain the best environmental treatment efficiency.

This Special Issue aims to explore efficient, economical, and environmentally friendly preparation methods for carbon-based catalysts and to explore their potential applications in the field of water and wastewater treatment. This Special Issue aims to provide new ideas for effectively promoting the application of carbon-based catalysts in the water environment.

We particularly welcome contributions concerning:

  • The preparation of carbon-based catalysts;
  • Applications for seawater desalination;
  • Applications for heavy metals pollution control;
  • Applications for organic pollution control;
  • Applications for nitrogen pollution control;
  • Applications for phosphorus pollution control.

Abstract
In this paper, Au and Cu nanoparticles were successfully loaded onto porous g-C3N4 material through a hydrothermal synthesis method. By adjusting the proportion of Cu, Au-5%Cu/C3N4, Au-10%Cu/C3N4, and Au-15%Cu/C3N4 [...] Read more.
In this paper, Au and Cu nanoparticles were successfully loaded onto porous g-C3N4 material through a hydrothermal synthesis method. By adjusting the proportion of Cu, Au-5%Cu/C3N4, Au-10%Cu/C3N4, and Au-15%Cu/C3N4, catalysts were prepared and used for the catalytic reduction of CO2 to methanol. Characterization analysis using high-resolution XPS spectra showed that with an increase in the doping amount of Cu, the electron cloud density on the Cu surface initially increased and then decreased. Electrons from Au atoms transferred to Cu atoms, leading to the accumulation of a more negative charge on the Cu surface, promoting the adsorption of partially positively charged C in CO2, which is more beneficial for catalyzing CO2. Among them, Au-10%Cu/C3N4 exhibited good reducibility and strong basic sites, as demonstrated by H2-TPR and CO2-TPD, with the conversion rates for CO2, methanol yield, and methanol selectivity being 11.58%, 41.29 g·kg−1·h−1 (0.39 μmol·g−1s−1), and 59.77%, respectively.
