Single and mixed oxide Al/Zr-pillared clay (Al/Zr-PILC) catalysts were synthesized and tested for catalytic wet air oxidation (CWAO) of aqueous phenol solution under milder conditions, in a semi-batch reactor. The catalysts were synthesized from natural bentonite clay using ultrasonic treatment during the aging and intercalation steps and were characterized <...

An organic-pillared coordination cage templated the quantitative formation of siloxane-bridged cyclophanes within its cavity via hydrolysis and condensation of 1,6- and 1,8-bis(trimethoxysilyl)pyrene.

A novel polyethersulfone (PES) mixed matrix membranes (MMMs) loaded with iron (Fe) pillared nanoclay was fabricated for efficient rejection of bisphenol (BPA) from water. Low–cost one dimensional (1D) halloysite (FePHNTs), two (2D) bentonite (FePB), and 2D Cloisite 15A (FePC15A) were synthesized via pillaring procedure. XRD, TEM, EDS BET results indicated that the nanoclays successfully pillare...

Removal of uranium [U(VI)] from aqueous solutions with humic acid-immobilized zirconium-pillared clay (HA-Zr-PILC) was investigated using a batch adsorption technique. The adsorbent was characterized using XRD, FTIR, SEM, TG/DTG, surface area analyzer and potentiometric titration. The effects of pH, contact time, initial concentration, adsorbent dose, and adsorption isotherm on the removal proc...

The microbiological contamination of water is responsible for millions of deaths in the world annually, until now the disinfection of water has been based on the chlorination; however there is a growing concern for the formation of trihalomethanes, for this reason it was evaluated the inactivation of total coliforms and Escherichia coli (E. coli) by using the advanced oxidation process known as...

The study of the intercalation of organic compounds into clays, as in the preparat ion of pillared clays, is of great importance both from the theoretical point of view and for its applications in pharmacy, agriculture, clay characterization, catalysis, etc. (MacEwan and Wilson, 1980; Theng, 1974; Pinnavaia, 1983). At different temperatures, intercalated organic molecules, especially long-chain...
