“…T t,g is the surface air temperature for model grid g at time t , and f i , t , g ( T t , g ) is the corresponding temperature sensitivity factor for source i . We defined γ i as the evaporable (i.e., ambient-temperature-sensitive) fraction of AVOC emissions from source i , which was the fugitive fraction of AVOC emissions from that source . Nonfugitive AVOC emissions, such as tailpipe exhaust from vehicles, are more affected by the temperature within engines and less affected by ambient temperature.…”

For transportation emissions, we assumed γ 1 = 0.39 based on emission tests for Chinese passenger vehicles and trucks in the year 2015.…”

“…However, measurements in 2021 showed that fugitive emissions still constituted more than half of the total VOC emissions from several industrial processes, including coating. 39 More measurements representative of current technologies are urgently needed to reduce the uncertainties of the parameters in Table 1 and better represent the temperature sensitivities of evaporative emissions of AVOC species from individual sources in China. Application of our parametrizations in regional models can help improve air quality forecasts and accentuate targets for emission reduction, providing policymakers with effective guidance in air quality management.…”

The evaporative emissions of anthropogenic volatile organic compounds (AVOCs) are sensitive to ambient temperature. This sensitivity forms an air pollution-meteorology connection that has not been assessed on a regional scale. We parametrized the temperature dependence of evaporative AVOC fluxes in a regional air quality model and evaluated the impacts on surface ozone in the Beijing−Tianjin−Hebei (BTH) area of China during the summer of 2017. The temperature dependency of AVOC emissions drove an enhanced simulated ozone-temperature sensitivity of 1.0 to 1.8 μg m −3 K −1 , comparable to the simulated ozone-temperature sensitivity driven by the temperature dependency of biogenic VOC emissions (1.7 to 2.4 μg m −3 K −1 ). Ozone enhancements driven by temperature-induced AVOC increases were localized to their point of emission and were relatively more important in urban areas than in rural regions. The inclusion of the temperature-dependent AVOC emissions in our model improved the simulated ozone-temperature sensitivities on days of ozone exceedance. Our results demonstrated the importance of temperature-dependent AVOC emissions on surface ozone pollution and its heretofore unrepresented role in air pollution−meteorology interactions.

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.
