“…The activation of this catalytic phase at high temperature provokes the Zr‐extraction of the pillars leading to WO 3 /ZrO 2 nanoparticles, which are highly active in esterification reactions . The excellent properties of the PCH has led to these materials can be used as catalytic support in the selective oxidation of H 2 S to elemental sulfur, using vanadium oxide as active phase with high activity and selectivity along the time on stream . In the same way, PCH has been employed to disperse Fe 2 O 3 particles in the toluene oxidation and the selective sulfur oxidation …”

Porous clay heterostructures (PCH) are obtained by the insertion of an organic bulky cation in the interlayer spacing of a smectite, causing a swelling of the clay mineral. Right after, oxides species, mainly silicon oxide, are incorporated as pillars galleries between adjacent layers to form a porous structure after the removal of the template. The ordering of the clay mineral as well the organic cation incorporated in the synthetic step favors the modulation of the textural properties of the PCH. In addition, the incorporation of heteroatoms in the pillars galleries can also modulate the acidity of the PCH. The modulation of the pore size and the acid properties provides to these materials a wide range of applications in the fields of adsorption and catalysis. This paper carries out a detailed review of the synthesis of PCH, characterization as well as uses and application reported in the literature.

“…In addition, PCHs have been also used as catalytic support in the NO reduction [31], partial oxidation of H 2 S [32], preferential oxidation of CO [33] or esterification reactions to obtain biolubricants [34]. The high applicability of the PCH in the fields of catalysis and adsorption is attributed to the existence of moderate acidity together with high specific surface area and homogeneous micro-and mesoporosity, which makes PCH potentially interesting for CO 2 adsorption.…”

In this study the removal of benzothiophene (BT) from a synthetic solution with n‐octane was evaluated using batch adsorption on modified mesoporous silicas impregnated with iron and cobalt species. The silica was modified to limit the aggregation and enlargement of mesochannels and produce a less ordered structure if compared to SBA‐15. The synthesized adsorbents were characterized by X‐ray diffraction (XRD), N2 adsorption/desorption isotherms at −196 °C, transmission electron microscopy (TEM), and X‐ray photoelectron spectroscopy (XPS). Adsorption equilibrium was investigated using different sulphur concentrations (3–15 mmol/L) and temperatures (30–50 °C). Under optimized conditions, the SBA‐15 sample modified with NH4F containing 10 g/g of Co showed the highest adsorption capacity (0.101 mmol/g), at 30 °C. Thus it may be inferred that these materials are promising for removal of sulphur in low concentrations from liquid fuels.
