FeO-Clinoptilolite nanoparticles: Brief characterization and its photocatalytic kinetics towards 2,4-dichloroaniline

Removal of Emerging Organic Pollutants by Zeolite Mineral (Clinoptilolite) Composite Photocatalysts in Drinking Water and Watershed Water

“…Especially, as one of the most representative zeolite minerals, clinoptilolite (CP) has great potential as an adsorbent to treat wastewater, and clinoptilolite-based composite photocatalysts exhibit outstanding photocatalysis performance in degrading EOPs in waters [57]. Nezamzadeh-Ejhieh's research team had carried out a lot of pioneering work on the preparation and application of CP-based composite photocatalysts [58][59][60]. The applications of CP for the catalytic degradation of hazardous organics make this material highly attractive for further research.…”

Powder XRD Study of Changes of Cd2+ Modified Clinoptilolite at Different Stages of the Ion Exchange Process

“…The crystallite size in our work is greater in comparison with a similar study [24]-175-180 nm vs 90-110 nm, which is due to a different degree of the zeolitization processes that have proceeded with time. Much lower values of the crystallite size are obtained by mechanical, thermal, and chemical pre-treatment of clinoptilolite-between 10 nm and 65 nm [35][36][37][38][39][40][41][42]. 2+ Cations in the Clinoptilolite Structure during Cadmium Exchange The designed initial model of the Cd-clinoptilolite structure was based on the data of Cappelletti et al [46] for natural clinoptilolite from volcanoclastites of North-Western Sardinia (monoclinic system, space group C2/m).…”

“…Mechanical tribo-and thermo-chemical treatment are the most often used methods to lower the size of the crystallites in the nanoscale range [35][36][37]. Iazdani and Nezamzadeh-Ejhieh [38,39] estimated, using the Scherrer equation, the average crystallite size of the pretreated via the ball-mill method clinoptilolite nanoparticles and FeO-and Ni-modified clinoptilolite samples. The value of the crystallite size obtained for the pretreated natural clinoptilolite is 56 nm.…”

Evaluation of band gap energy of TiO2 precipitated from titanium sulphate

“…It is important to emphasize that this procedure, which ignores the nature of electronic transition between the valence and conduction bands in obtaining 𝐸 𝑔 , is not the more suitable one as demonstrated by López and Goméz [13]. Therefore, J o u r n a l P r e -p r o o f the main goal of this work is to discuss the appropriate method to obtain 𝐸 𝑔 [14][15][16][17] and compare the newly calculated values with those presented by Kucio et al [12].…”
