Electrochemical activity of iron in acid treated bentonite and influence of added nickel

On the key role of the surface of palygorskite nanofibers in the stabilization of hexagonal metastable β-Ag2CO3 phase in palygorskite-based nanocomposites

“…In such hetero structures, several kinds of organic (Rahman et al, 2017;Tominaga et al, 2016), bio-organic (Darder et al, 2017;Ilsouk et al, 2017;Roque-Ruiz et al, 2016) and inorganic (Lakbita et al, 2016;Praneetb and Paria, 2017) guest species can be assembled, according to different synthesis approaches based eitber on intercalation by ion exchange (Roy et al, 2017) or grafting to SiOH groups, with host phyllosilicates (Aït . These combinations can act in a synergistic way giving rise to multifunctional materials witb optimum structural and texturai properties which can be destined to various versatile and innovative applications as heterogeneous catalysts in petroleum cracking (Emam et al, 2008), photocatalysts in environmental protec tion (Bouna et al, 2011;Lakbita et al, 2016;Pérez-Carvajal et al, 2016), molecular sieves (Liu and Wang, 2017), selective adsorbents (Boudriche et al, 2015;Msaadi et al, 2017), thermal insulators (Darder et al, 2017;Jahani et al, 2015;Laufer et al, 2012), electrochemical, electroanalytical and optical devices (Mudrinié et al, 2015;Tominaga et al, 2016;Kenne Dedzo et al, 2017) and inhibition systems in me tallic corrosion (Aït Aghzzaf et al, 2012;Aït Aghzzaf et al, 2014;Aït Aghzzaf et al, 2017).…”
