“…This pattern of peaks indicates that the main phase of this natural zeolite is clinoptilolite. The same trend of finding was reported in the literature [39]. Additionally, a slight amount of quartz and cristobalite phases were found in the XRD pattern of this natural zeolite sample.…”

“…An alternative is the use of treatments to eliminate these impurities and improve the physicochemical properties, thus enabling the application of these natural materials in a wider variety of processes. Textural characteristics, such as specific surface area, pore volume, pore size, and acidity, are extremely important for applications in adsorption and catalysis [6,11,12]. For this reason, bases, acids, and hydrothermal treatments can be applied post-synthesis to remove impurities and improve some physicochemical properties of natural materials [2].…”

“…Thepost-synthesis basic treatment of zeolites is widely applied and involves the preferential extraction of Si from the structure by hydrolysis in the presence of OH − . This treatment alters the specific surface area and pore size, generates mesoporosity, and improves the adsorption capacity and accessibility, and in addition, enriches the aluminum content and thus improves the acidic properties of the zeolite [11,12,14,15], which is very important for application in catalysis. In this sense, the parameters of the basic treatments applied to natural zeolite materials, such as concentration, time, and temperature, should be studied in order to improve the ability to obtain materials with improved and specific final properties.…”

“…The mechanism and operating conditions of RADS over Ni/ ZnO-based adsorbent has been attracted more attention in recent studies. [10][11][12][13][14][15][16][17] Bezverkhyy et al studied the kinetics of thiophene reactive adsorption on Ni/ZnO. 18,19 Their results indicated that the reaction between Ni/ZnO and thiophene consists of three steps.…”
