Special Issue Information

Dear Colleagues,

This Special Issue includes a collection of articles focused on the recent advances in catalytic ordered transformation and applications. Catalytic ordered transformation (COT) is a chemical reaction in which certain chemical substances are converted into other types of products using selective catalysts. COT is used in many research fields, including energy, environment, and chemistry, to promote high yields of particular products with less environmental pollution. COT has received much attention in recent years, owing to strict legal regulations governing environmental protection and a high demand for product yield from industry. Furthermore, COT research publications have increased dramatically in recent decades, particularly in the areas of the homo-/heterogeneous oxidative dehydrogenation of propane (ODHP), volatile organic compounds (VOCs), nitrogen volatile organic compounds (NVOCs), carbon monoxide (CO) abatement, nitrogen oxides (NOx) selective conversion, Fischer–Tropsch (FT) synthesis, and methane reforming (dry and steam reforming). Therefore, COT must be investigated further, including active and stable catalysts, preparation strategies, comprehensive characterizations, and surface mechanisms from both experimental and kinetic modelling perspectives.

The topics that are covered include, but are not limited to:

  • Tailored design of more stable, efficient, selective and cost-effective COT catalysts;
  • Advanced synthesis methods to correlate the thickness, morphology and ionic states;
  • Application of COT to energy storage and conversion;
  • The effects of CO2 and water vapor adsorption on the surface of COT catalysts;
  • Studies on the mixture of NOx, SOx and VOCs, NVOCs to reproduce the real emission control;
  • Studies on MnOx as a catalyst support for FT synthesis and methane reformation due to its sulfur and water-resistant effects;
  • Controlled synthesis of single-atom catalysts for steam methane reformation and FT synthesis;
  • Studies on the conversion of low-cost industrial by-products to high-demand chemical products, such as dehydrogenation ethane to ethylene and oxidative dehydrogenation of propane (ODHP);
  • Studies on the reaction pathway control that will reduce secondary reaction intermediates to achieve the desired product;
  • Theoretical calculations of the thermo data of surface species and rate constants of heterogeneous reactions.

Carbon nitride MXene exhibits good metal conductivity, high photothermal conversion, carrier mobility, and high exposure of active sites, which makes it a promising co-catalyst for photothermal synergistic transformation of CO2. In this paper, Ti3CN/TiO2 heterojunction was constructed in situ using Ti3CN as TiO2 precursor to investigate the performance of Ti3CN MXene in photothermal synergistic transformation of CO2, and then the monolayer structure was utilized to enhance the interfacial charge transfer and improve the photothermal catalytic activity of Ti3CN. The catalysts were characterized by SEM, XRD, XPS, and UV-Vis DRS, and it was found the heterojunction constructed by monolayer MXene had a narrower bandgap and a higher carrier generation mobility, which, combined with the catalytic activity test, proved the single monolayer Ti3CN MXene had better photothermal synergistic conversion efficiency of CO2, and the heterojunction yield was 11.36 μmol·g−1·h−1 after layering, compared with that before layering (9.41%), which was 1.2 times higher than that before layering (9.41 μmol·g−1·h−1).
