A mesoporous carbon (CMC) has been treated under acidic conditions (32.5 wt% HNO3 at 10 °C or 40 °C) to prepare two new carbon samples (HCMC10 and HCMC40), which developed higher acidity in terms of quantity of sites and surface acid strength. The

Solid acids are the green alternative for heterogeneous acid catalysis, in particular for industrial processes exploiting biomass. Niobium–phosphorus oxides are valid candidates owing to their specific acidic properties and tolerance to water, on t

This study deals with the use of calcium hydroxyapatite (HAP) materials as adsorbents for removing heavy metal ions from polluted waters. The synthesis conditions (i.e. P/Ca stoichiometry and nature of the solvent) of HAP samples were properly varied

The adsorption properties of NO on copper-based catalysts stabilized on crystalline (ZSM-5) and amorphous (SiO 2 –Al 2 O 3 ) matrices prepared by different methods have been studied. The catalysts were prepared by ionic exchange on the two matrices

The pyrolysis of γ-Al2O3- and ZrO2-supported [Co4(CO)12] and [Rh4(CO)12] gives highly dispersed metal systems whose electronic properties have been studied by e.s.r. spectroscopy. Paramagnetic formal RhII species (g∥= 2.21, g⊥= 2.11) were observ

Paramagnetic metal and oxygen species observed when alumina-(or zirconia-supported rhodium, Rh/γ-Al2O3(ZrO2), is obtained by the decarbonylation of [Rh4(CO)12]-Al2O3(ZrO2) are discussed as a function of the decarbonylation temperature (250–600 °C
