“…Iron-enriched zeolite catalysts are mainly active at medium, and high temperatures [ 150 ]. An example is the Fe-ZSM-5 zeolite, which shows high activity in the temperature range of 300 °C to 450 °C [ 157 ]. However, at such high temperatures, carbon deposition can occur and slow down the process [ 158 ].…”

Zeolites, a group of minerals with unique properties, have been known for more than 250 years. However, it was the development of methods for hydrothermal synthesis of zeolites and their large-scale industrial applications (oil processing, agriculture, production of detergents and building materials, water treatment processes, etc.) that made them one of the most important materials of the 20th century, with great practical and research significance. The orderly, homogeneous crystalline and porous structure of zeolites, their susceptibility to various modifications, and their useful physicochemical properties contribute to the continuous expansion of their practical applications in both large-volume processes (ion exchange, adsorption, separation of mixture components, catalysis) and specialized ones (sensors). The following review of the knowledge available in the literature on zeolites aims to present the most important information on the properties, synthesis methods, and selected applications of this group of aluminosilicates. Special attention is given to the use of zeolites in agriculture and environmental protection.

“…Except for precursors (volatile organic compounds and nitrogen oxides 12,13 ), which from industrial emissions, vehicle exhaust and soil volatilization [14][15][16] , which can cause ozone pollution, also meteorological conditions and atmospheric circulation can affect it. Previous studies indicated that circulation classification is helpful for exploring the effect.…”

It’s essential to clarify the complex interactions between atmospheric circulation, climate, and ozone pollution. In this study, we observed that meteorological factors and circulation types affecting ozone concentrations in China exhibit significant regional differences. The interannual variability of atmospheric circulation strongly influence the interannual variability of ozone, with the contribution of it varying from 74% to 99% across the 10 regions we examined. Interannual fluctuations in ozone concentration are primarily caused by changes in the intensity of atmospheric circulation types. Additionally, among all circulation types, heavily polluted type of Chinese ozone accounts for 23.95%, caused by EOF1 mode (Arctic Oscillation), while EOF2 mode is identified as impact mechanisms for the clean type of Chinese ozone. However, circulation that leads to ozone pollution will increase, and it is noteworthy that Chinese ozone levels under the comprehensive influence of atmospheric circulation and meteorology are expected to increase in the foreseeable future.

“…As the main contributors to both particulate matter and ground-level ozone, the NO x and VOCs do great harm to both the environment and the human body [2]. To eliminate these air pollutants, various technologies have been well developed [3]. Typically, the NOx could be effectively removed via adsorption and catalytic reduction (i.e., Selective Catalytic Reduction) [4], while the elimination of the VOCs was usually achieved by adsorption and catalytic oxidation [5].…”

“…The intrinsic porous structure not only provides very good places for capturing the reactant (pollutants) but also offers superior conditions for the distribution of extraneous active species (metal) to efficiently convert the pollutants to harmless substances [8]. For example, the Fe-ZSM-5 zeolite shows good selective catalytic reduction activity for the NO x in the NH 3 -SCR reaction at 300~450 • C. But its activity temperature window is relatively narrow; therefore, in recent years the Cu-SSZ-13 is generally used for the selective catalytic reduction of NO x from vehicle emission at high temperatures of 200~500 • C [3]. To compensate for the lowtemperature activity of the Cu-SSZ-13 below 200 • C, it is found that the Pd-SSZ-13 zeolite possesses the ability to store NO x at 80~180 • C [2].…”

Zeolite-based materials are widely used as adsorbents and catalysts for purifying air pollutants like NOx and VOCs due to abundant pore structure, regular pore distribution, and numerous ion exchange sites. Thermal treatment is a necessary procedure for both removing impurities in pores and promoting the metal active dispersed evenly before the zeolite-based adsorbents/catalysts were applied for purifying the NOx/VOCs. Nevertheless, the conventional thermal field treatment (i.e., high-temperature calcination, high-temperature purging, etc.) takes large energy consumption. In contrast, unconventional external-field treatments such as non-thermal plasma and microwave show significant advantages of high efficiency, low energy consumption as well and low pollution, which were used to substitute the traditional thermal treatment in many fields. In this paper, the roles of non-thermal plasma or microwave in the adsorption/catalysis of the NOx/VOCs are reviewed from three aspects assisting activation of materials, cooperative catalysis process, and assisting zeolites synthesis. The reasons for unconventional treatments in improving textural properties, active sites, performance, etc. of zeolite-based materials were illuminated in detail. Moreover, the influences of various parameters (i.e., power, time, temperature, etc.) on the above aspects are elaborated. It is hoped that this review could provide some advanced guidance for the researchers to develop highly efficient materials.
