Various methods including acid treatment, heat treatment and surface modification have
been used to improve the adsorption properties of natural palygorskite. However, the …

A facile method for the preparation of stable palygorskite/methylene blue@ SiO 2 (PAL/MB@
SiO 2) Maya Blue-like pigment was reported. The PAL/MB pigment was prepared via …

A compositional gap between sepiolite and palygorskite has long been accepted even
though they have similar structures, but recent studies found that such a gap does not exist …

The nanoscale dispersion of the crystal bundles or aggregates of natural palygorskite (PAL)
is the key factor to prepare a stable PAL-based hybrid nanocomposite. The appropriate …

The exact recipe to prepare the ancient Maya Blue (MB), an incredibly resistant and brilliant
pigment prepared from indigo (dye) and Palygorskite (clay), is lost to the ages. To unravel …

A series of data from voltammetric, spectral, and UPLC–MS and Py–GC–MS analyses of
extracts from synthetic Maya Blue-type specimens provides evidence on the presence of a …

A study based on the use of pyrolysis-silylation-gas chromatograpy–mass spectrometry (Py-
GC–MS), which aimed to identify indigoid compounds and to clarify the multicomponent …

Inspired by Maya Blue, we report the fabrication of stable “Maya Red” pigments with a purple-
red hue by adsorption of cationic red X-GRL (CR-X-GRL) onto palygorskite (PAL), which is …

A new approach to describe the composition of Maya blue (MB), an ancient organic–
inorganic hybrid material, is presented. It is based on the analysis of attenuated total …

The interaction between H 2 molecules within the structure of microporous clays is an
interesting topic, with applications including gas storage, nuclear waste containment, and …
