The investigation of the metal oxide/inorganic ion interface at the atomic level represents a fundamental issue for the understanding of chemical and physical processes involved in several fields such as catalysis, adsorption, directed synthesis and the mechanistic study of crystal growth. In this paper, a combined hydrothermal synthesis and computational approach based on DFT theory is adopted...

c-Alumina-based materials with high porous volume, tunable pore size, were synthesized by the addition of both PEO/PPO/PEO triblock copolymers (Pluronics F127 and P123) and metal nitrates (Al, Mn, Cu) in a boehmite (AlOOH) nanoparticle hydrosol. During the subsequent thermal treatment, the surfactant was removed leaving a highly porous framework. The pore size distribution was strongly dependen...

the reaction of 3-chloropropyl boehmite nanoparticles with caffeine and sulfuric acid afforded bnps-3-propyl-imidazolopyridinium hydrogen sulfate [bnps-caff]hso4 as a new bnps-supported ionic liquid (il) catalyst. [bnps-caff]hso4 proved to be an efficient heterogeneous catalyst for the synthesis of pyrazolopyranopyrimidines via a one-pot four-component reaction of hydrazine hydrate, ethyl aceto...

It is of great importance to develop a spherical γ-alumina support with high hydrothermal stability be used in platinum reforming catalyst processes. The porous pseudo-boehmite powder surface area was first synthesized via simple separate nucleation and aging steps method, then as precursor produce γ-Al2O3 an oil–ammonia column method. as-synthesized has substantially greater specific 336.0 m2·...

Boehmite applications are often subject to specific characteristics in terms of morphologies and surface properties. The versatile continuous supercritical hydrothermal method allows synthesizing various boehmite from rhombic hexagonal platelet-like nanoparticles depending on the preferential adsorption part precursor after transformation species (020) resulting a growth along [001] mostly [100...
