“…Temperature is pivotal for the performance of bifunctional materials in toluene oxidation, with reaction rates increasing with temperature to an optimal point, as evidenced by Zhang et al.′s study on Mn‐MOFs, where the highest catalytic efficiency for toluene oxidation was at 300 °C, linked to the number and accessibility of active sites [224] . Yao et al.′s research revealed that the Rh1Cu3/ZSM‐5 catalyst achieved peak efficiency for toluene oxidation at 262 °C, underscoring temperature‘s vital influence on bifunctional material efficacy, with moderate temperatures enhancing VOC oxidation more than conventional catalysts [225] . A list of bifunctional materials for the treatment of VOCs are presented in Table 9.…”

Volatile organic compounds (VOCs) are gases that are emitted into the air from products or processes and are major components of air pollution that significantly deteriorate air pollution and seriously affect human health. Different types of metals, metal oxides, mixed‐metal oxides, polymers, activated carbons, zeolites, MOFs and mixed‐matrixed materials have been developed and used as adsorbent or catalysts for diversified VOC capture, removal, and destruction. In this comprehensive review, we first discuss the general classification of VOC removal materials and processes and outline the historical development of bifunctional and cooperative adsorbent‐catalysts for the removal of volatile organic compounds (VOCs) from air. Subsequently, particular attention is devoted to design strategies for cooperative adsorbent‐catalysts, along with detailed discussions on the latest advances on these bifunctional materials, reaction mechanisms, long‐term stability, and regeneration for VOCs removal processes. Finally, challenges and future opportunities for the environmental implementation of these bifunctional and cooperative adsorbent‐catalysts are identified and outlined with the intent of providing insightful guidance on the design and fabrication of more efficient materials and systems for VOCs removal in the future.

Volatile organic compounds (VOCs) are toxic and are considered the most important sources for the formation of photochemical smog, secondary organic aerosols (SOAs), and ozone. These can also greatly affect the environment and human health. For this reason, VOCs are removed by applying various technologies or reused after recovery. Catalytic oxidation for VOCs removal is widely applied in the industry and is regarded as an efficient and economical method compared to other VOCs removal technologies. Currently, a large amount of VOCs are generated in industries with solvent-based processes, and the ratio of aromatic compounds is high. This paper covers recent catalytic developments in VOC combustion over noble-metal-based catalysts. In addition, this report introduces recent trends in the development of the catalytic mechanisms of VOC combustion and the deactivation of catalysts, such as coke formation, poisoning, sintering, and catalyst regeneration. Since VOC oxidation by noble metal catalysts depends on the support of and mixing catalysts, an appropriate catalyst should be used according to reaction characteristics. Moreover, noble metal catalysts are used together with non-noble metals and play a role in the activity of other catalysts. Therefore, further elucidation of their function and catalytic mechanism in VOC removal is required.

“…This peak was assigned to strong adsorption strength and, thus, a delay in desorption and a more complicated regeneration. Using XPS analysis, it was demonstrated that the improvement of Pt dispersion on hierarchical mordenite led to an increase of the active oxygen species (an increase of O ads / O lat ) [102] . Yao et al evaluated the catalytic performance of the Rh 1 Cu y /ZSM-5 materials with different copper content (y = 1, 3, 5, 10) for the total oxidation of toluene using a Langmuir-Hinshelwood model [103] .…”

Volatile Organic Compounds (VOCs) are known to be hazardous and harmful to human health and the environment. In mixtures or during repeated exposures, significant toxicity of these compounds in trace amounts has been revealed. In vitro air-liquid interface approaches underlined the interest in evaluating the impact of repeated VOC exposure and the importance of carrying out a toxicological validation of the techniques in addition to the standard chemical analyses. The difficulties in sampling and measuring VOCs in stationary source emissions are due to both the complexity of the mixture present and the wide range of concentrations. The coupling of VOC treatment techniques results in efficient systems with lower operating energy consumption. Three main couplings are outlined in this review, highlighting their advantages and relevance. First, adsorption-catalysis coupling is particularly valuable by using adsorption and catalytic oxidation regeneration initiated, for example, by selective dielectric heating. Then, several key aspects of the plasma catalysis process, such as the choice of catalysts suitable for the non-thermal plasma (NTP) environment, the simultaneous removal of different VOCs, and the in situ regeneration of the catalyst by NTP exposure, are discussed. The adsorption-photocatalysis coupling technology is also one of the effective and promising methods for VOC removal. The VOC molecules strongly adsorbed on the surface of the photocatalyst can be directly oxidized by the photogenerated hole on the photocatalyst (e.g., TiO2).
