Special Issue Information

Dear Colleagues,

Nanoscale material catalysis is actively studied in the field of environmental protection. It has great potential and unique superiority in various aspects such as air pollutant elimination, wastewater purification, soil remediation, waste disposal, and CO2 conversion. The issues of how to synthesize efficient and highly selective catalysts and reveal the reaction/ inactivation are important topics in this field.

This Special Issue aims to report the latest innovative research and development in nanoscale material catalysis for the environmental protection field, covering a broad range of topics, including the design, synthesis, and application of nanoscale catalysts for pollutant removal or conversion in air, water, and soil. Revealing the related reaction/deactivation mechanism using various experimental and theoretical calculation means is also encouraged. We welcome contributions from all related groups that contribute to our understanding of this exciting and rapidly advancing field.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Nanoscale catalyst synthesis, characterization for environmental applications.
  • Catalytic mechanisms and strategies for catalyst activation and regeneration.
  • Catalytic strategies aimed at abating environmental pollutants, including air pollutants (such as nitrogen oxides and volatile organic compounds), water pollutants, and soil pollutants.
  • Catalytic reactions that adeptly transform CO2 into valuable and useful products.

We look forward to receiving your contributions.

A cellulose-based carbon aerogel (CTN) loaded with titanium dioxide (TiO2) and graphitic carbon nitride (g-C3N4) was prepared using sol–gel, freeze-drying, and high-temperature carbonization methods. The formation of the sol–gel was carried out through a one-pot method using refining papermaking pulp, tetrabutyl titanate, and urea as raw materials and hectorite as a cross-linking and reinforcing agent. Due to the cross-linking ability of hectorite, the carbonized aerogel maintained a porous structure and had a large specific surface area with low density (0.0209 g/cm3). The analysis of XRD, XPS, and Raman spectra revealed that the titanium dioxide (TiO2) and graphitic carbon nitride (g-C3N4) were uniformly distributed in the CTN, while TEM and SEM observations demonstrated the uniformly distributed three-dimensional porous structure of CTN. The photocatalytic activity of the CTN was determined according to its ability to degrade rhodamine B. The removal rate reached 89% under visible light after 120 min. In addition, the CTN was still stable after five reuse cycles. The proposed catalyst exhibits excellent photocatalytic performance under visible light conditions. Full article
