Special Issue Information

Dear Colleagues,

This Special Issue of Catalysts, Catalytic Gas Exhausts Emission Control, will address the main areas of current research in the fields of novel catalyst synthesis, process development/simulation and technology, and issues and challenges related to the exhaust gases emissions control and air pollution remediation.

Exhaust gases from both mobile and stationary applications and industrial facilities largely comprise oxides of nitrogen and sulfur, volatile organic compounds (VOCs), CO, CO2, water vapor, partially reacted and unburned hydrocarbons (HC), and particulate material. According to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), atmospheric concentrations of exhaust and greenhouse gases (GHG), in particular carbon dioxide, methane, and nitrous oxide, from anthropogenic sources have reached unprecedented levels at least over the past 800,000 years, being largely responsible for air pollution, acidification, global warming, and human diseases. In particular, the increasing worries about the correlation between air quality and human health has boosted, in the last decades, the environmental concerns about exhaust gas emissions control, leading to systematic exploitation of catalytic technologies for the environmental safeguard and remediation.

Therefore, we invite contributions in the form of original research papers, detailed reviews, or mini-reviews in, but not limited to, the specialized fields outlined below:

  1. Recent development in current exhaust after-treatment technologies;
  2. Development of novel catalytic materials and processes for the VOCs and methane emissions control and abatement;
  3. Kinetic studies and reaction modeling for the catalytic exhaust gas abatement;
  4. Recent advancement in the use of photocatalysis for environmental remediation;
  5. Design and development of electrocatalysts and electrochemical reactors for the abatement of air pollutant;
  6. Recent advancement in CO2 capture and utilization technologies based on catalytic, photocatalytic end electrochemical processes;
  7. Novel catalysts for the low-temperature CO oxidation reaction;
  8. Development of new gas sensors for stationary and mobile applications.

We believe that this Special Issue will provide an excellent platform for researchers to share their newest scientific advancements in the field.

Direct catalytic methanation of CO2 (from CO2/CH4 biogas mixture) to produce biomethane was conducted in a pilot demonstration plant. In the demonstration project (MeGa-StoRE), a biogas desulfurization process and thermochemical methanation of biogas using hydrogen produced by water electrolysis were carried out at a fully operational biogas plant in Denmark. The main objective of this part of the project was to design and develop a reactor system for catalytic conversion of CO2 in biogas to methane and feed biomethane directly to the existing natural gas grid. A process was developed in a portable container with a 10 Nm3/h of biogas conversion capacity. A test campaign was run at a biogas plant for more than 6 months, and long-time operation revealed a stable steady-state conversion of more than 90% CO2 conversion to methane. A detailed catalytic study was performed to investigate the high activity and stability of the applied catalyst. Full article

Abstract
To improve propane combustion activity and illustrate the promotional effects of molybdenum doping, Pt-Mo/ZSM-5 catalysts with different Mo amounts were prepared by the co-impregnation method. XRD, Raman, H2-TPR, NH3-TPD, in situ DRIFTs, XPS and other characterizations were performed. The [...] Read more.
To improve propane combustion activity and illustrate the promotional effects of molybdenum doping, Pt-Mo/ZSM-5 catalysts with different Mo amounts were prepared by the co-impregnation method. XRD, Raman, H2-TPR, NH3-TPD, in situ DRIFTs, XPS and other characterizations were performed. The results indicated that the concentration of Pt0 in Pt/ZSM-5 catalyst increased after the doping of Mo and the content of Pt0 had a positive correlation with the reaction turnover frequency value. The propane combustion activity of Pt/ZSM-5 catalyst was significantly improved after the doping of molybdenum species. Among all the catalysts, Pt-6Mo/ZSM-5 catalyst (Pt/ZSM-5 with 6 wt.% Mo modification) showed the lowest T50 and T90 for propane catalytic combustion. Moreover, the Pt-Mo/ZSM-5 catalyst exhibited outstanding catalytic stability. Full article
