Special Issue Information

Dear Colleagues,

Unbridled industrial expansion and modernization have dramatically increased both outdoor and indoor air pollution. Carcinogenic volatile organic compounds (VOCs) such as formaldehyde and aromatic/aliphatic hydrocarbons are the primary targets for safeguarding human health and pristine environment due to their hazardous propensity. Other air pollutants such as carbon monoxide, hydrogen sulfide, ammonia, halogens, nitrogen oxides, sulfur oxide, and particulate matter must be effectively controlled due to their deleterious effects on the ecosystem and human health. There is also a growing concern regarding capturing and utilizing carbon dioxide in light of the issues surrounding climate change. In this regard, recent years have witnessed a dramatic rise in applying advanced functional materials as superior media for the effective removal of various gaseous pollutants. The primary mechanisms of interest governing the material–pollutant interaction and removal process include physicochemical and reactive adsorption, along with thermo-, photo-, and photothermal catalysis. Other synergistic mechanistic combinations can also be explored.

In recognition of the need to develop functional materials capable of maintaining appreciable performance even under harsh real-world conditions, the open-access journal Atmosphere is hosting a Special Issue to showcase the most recent findings related to air quality management using advanced functional materials. With the recent expansion of research showing novel synthesis approaches for unique materials, this Special Issue is also an appropriate venue for papers focusing on innovative synthesis approaches for high-performing advanced materials. Ultimately, this Special Issue aims to showcase the most recent research finds in the synthesis and application of advanced functional materials aimed towards effectively removing various air pollutants.

Original results from controlled investigations and the field, mathematical modeling, simulation, and review papers related to the application of advanced functional materials for air quality management are all welcome contributions. Authors are encouraged to include brief descriptions regarding future research directions and current shortcomings related to their expertise on the 5- to 10-year timeline.

The objective of this research was to investigate the behavior and conditions for CO2 adsorption using a mixture of CO2/N2 over a fixed-bed column of zeolite 5A. The study was performed with a variation in gas composition of CO2/N2 as a 20/80, 50/50, and 80/20 volume %, the adsorption temperatures as 298, 333, and 373 K and the total feed flow rates as 1, 2, and 4 L/h under 100 kPa pressure. The Bohart–Adams, Yoon–Nelson, and Thomas models were used to predict the breakthrough behavior of CO2 adsorption in a fixed column. Furthermore, the adsorption mechanism has been investigated using the kinetics adsorption of pseudo-first-order, pseudo-second-order, Boyd model, and intraparticle model. Increasing the CO2 composition of a gas mixture resulted in a high CO2 adsorption capacity because of the high partial pressure of CO2. The capacity of CO2 adsorption was decreased with increasing temperature because of physical adsorption with an exothermic reaction. The CO2 adsorption capacity was also decreased with increasing feed flow rates with inadequate time for CO2 adsorbates diffusion into the pores of the adsorbent before exiting the packed bed. The CO2 adsorption by zeolite 5A confirmed that the physical adsorption with intraparticle diffusion was the rate-controlling step of the whole process. Full article

The objectives of the research were to develop synthesis and estimation of each factor on carbon dioxide adsorption of advanced functional zeolite NaY material derived from bagasse ash and rice husk ash with different crystallization temperatures and weight percentages of zinc by the ion exchange method. The adsorbents were tested in a packed bed reactor at different temperatures and flow rates of carbon dioxide. The Minitab program was used to estimate the effects of each factor on carbon dioxide adsorption properties. The results showed that extracted silicon dioxide from bagasse ash and rice husk ash could be successfully used as raw material for zeolite NaY synthesis with a crystallization temperature of 298.15 K. The zeolite NaY crystalline structure was well-preserved after ion exchange. The highest capacity of carbon dioxide adsorption was at 10.33 mmol/g with zeolite 5B298-373-1. The results of the Minitab program showed that the carbon dioxide adsorption decreased with increasing crystallization temperature and carbon dioxide flow rate parameters. However, the increased weight percentage of zinc loading on zeolite NaY resulted in better carbon dioxide adsorption. The factors of the types of adsorbents and adsorption temperature showed interaction with each other. Full article
