Characterization and catalytic performance of Fe3Ni8/palygorskite for catalytic cracking of benzene [PDF]

, 2013
Catalytic decomposition is a very attractive way to convert tar components into H2, CO and other useful chemicals. The performance of Fe3Ni8/PG (palygorskite, PG) reduced in hydrogen at different temperatures for the catalytic decomposition of benzene ...

Effect of Natural Nanostructured Rods and Platelets on Mechanical and Water Resistance Properties of Alginate-Based Nanocomposites

Frontiers in Chemistry, 2018
A series of biopolymer-based nanocomposite films were prepared by incorporating natural one-dimensional (1D) palygorskite (PAL) nanorods, and two-dimensional (2D) montmorillonite (MMT) nanoplatelets into sodium alginate (SA) film by a simple solution ...

Mg K-edge XANES of sepiolite and palygorskite

, 2005
We present a study of the Mg K-edge on sepiolite and palygorskite performed at the INFM BEAR beamline at Elettra synchrotron light source (Trieste). These two clays, although having very similar structures, show some different features in their near-edge.
