Special Issue Information

Dear Colleagues,

The development of new materials for gas capture and conversion has gained significant attention due to growing environmental concerns and the need for sustainable energy. For instance, the capture and conversion of CO2 based on novel sorbents and catalysts has been recognized as one of the most promising approaches to mitigate global warming and provide valuable products. The separation and purification of various hazardous gases, including SOx, NOx, VOCs, and heavy metals, are of great significance for environmental protection. Nowadays, the fabrication of new materials with superior performance for gas capture and conversion and the in-depth investigation of the related mechanisms have become the focus of studying.

This Special Issue aims to promote and disseminate state-of-the-art knowledge on new materials for efficient gas capture and conversion. In this Special Issue, original research articles and reviews are welcome. The research scope may include (but is not limited to) the following:

  1. Various materials (liquid/solid sorbents, membranes, etc.) for gas capture from complicated environments;
  2. Noval catalysts for gas conversion to provide valuable products or purify contaminants;
  3. Kinetic modelling, thermodynamic analysis, and process simulation for gas capture and conversion;
  4. Other applications involving gas capture and conversion.

Ammonia borane is a promising hydrogen storage material due to its high hydrogen content, but its use as hydrogen carrier under thermal stimuli involves the production of several byproducts, such as borazine, reducing hydrogen purity and the overall efficiency. This work is focused on the use of high-boiling-point amines to modulate ammonia borane decomposition, aiming to enhance hydrogen release and suppress volatile NxBy species. Kissinger’s equation kinetics revealed that amines significantly influence the decomposition mechanism, and TGA-IR investigation showed a maximum of 2.4 wt.% of pure hydrogen release in the presence of triphenyl amine. Furthermore, the experimental data herein discussed, together with a computational study of activation energies, allowed us to derive a detailed mechanism that leads to a foundation for further advancement in the exploitation of ammonia borane as a hydrogen carrier, suggesting that the formation of linear species is anchored to amine over the release of borazine and production of poly borazine-like species.
