About this Research Topic
It has been known for some time that volatile organic compounds (VOCs) are exceptionally damaging to the environment. Despite heavy regulation, the emission of such substances remains widespread, particularly in urban and industrialized areas. It is therefore critical that efficient technologies and infrastructure for the abatement of VOCs are developed to negate their potentially devastating environmental impact. The oxidation of VOCs over heterogeneous catalysts is a pertinent example of such technology and represents a promising solution. This is a fertile, interesting field of research that is continuously developing. As guest editors, we hope this invited issue will provide the readers of Frontiers in Nanotechnology an exciting insight into the cutting-edge research taking place in this field.
It is incredibly important not only to synthesize and characterize catalysts and nanocatalysts which are highly active for VOC abatement but to ensure that the performance of such materials is maintained under industrially relevant conditions. In many industrial settings where VOCs are emitted, the flue gas often contains numerous other contaminants, such as H2O or SOx, which can lead to reductions in catalytic performance and in some cases, complete catalytic deactivation. Collectively as guest editors, we see this as an important challenge that must be addressed if the interesting developments in this field are to be recognized in an industrial setting. For this invited issue, we, therefore, welcome research that focuses on overcoming these obstacles.
The research open for consideration in this Research Topic should involve experiments conducted under industrially-relevant conditions. Emphasis must be placed on the characterization of the catalytic nanomaterials under investigation. The primary area of study can, however, span a broad research area, which focusses on:
• VOC oxidation over supported metal catalysts or metal/mixed metal oxides
• Heterogeneous surface mechanisms in VOC oxidation (through use of in-situ techniques or theoretical calculation)
• Deactivation and/or regeneration mechanisms in VOC oxidation. Should include extensive characterization of both the fresh and used catalysts.
• Review of chemical contaminants present in commercial flue streams
• Further areas for development (perspectives)
Given that VOC oxidation is often a complex process, the formation of hazardous by-products in VOC oxidation reactions must also be considered. As such, all contributions must include careful quantification of the reaction products formed.
