Pd nanoparticles stabilized on the Schiff base-modified boehmite: Catalytic role in Suzuki coupling reaction and reduction of nitroarenes

Journal of Organometallic Chemistry, 2019
Palladium nanoparticles (Pd NPs) were decorated on Schiff base-modified boehmite (Sch-boehmite) particles via a simple method without deploying any additional reducing agents and their structure was confirmed by different characterization methods.

Boehmite-supported vanadium oxide catalysts

Applied Catalysis A: General, 1998
Abstract Two crystalline boehmites obtained by hydrothermal synthesis at 393 and 473 K have been studied as model supports for vanadium oxide, deposited by the equilibrium adsorption method. Supports and catalysts have been characterized by X-ray Diffraction, TGA, TEM, UV-Visible and Near Infrared Diffuse Reflectance Spectroscopy, FT-IR, XPS and 27 ...

Role of boehmite/solution interface in boehmite precipitation from supersaturated sodium aluminate solutions

Hydrometallurgy, 2004
This work presents the developments made in the Laboratory of Metallurgy of the National Technical University of Athens in the field of boehmite precipitation from supersaturated sodium aluminate solutions under atmospheric conditions. Initially, the boehmite process is described by giving emphasis to kinetic problems that reduce the process efficiency

Autoprecipitation of Gibbsite and Boehmite

2016
When thick bauxite slurry was heated up to 160°C, boehmite precipitation was observed and caused scale formation on the surface of heat exchangers in digestion step.

Properties of the boehmitized aluminium surface

Surface Technology, 1982
Abstract The system boehmitized aluminium-aqueous solution was investigated over a broad pH range by contact angle and ζ potential measurements. Both measurements gave significant results. The contact angle as a function of pH shows a pronounced maximum, while the ζ potential is a linear function of pH.

Electrochemistry of the boehmite—water interface

Colloids and Surfaces, 1990
Abstract The surface charge and the zeta potential of boehmite have been determined as a function of pH and KNO 3 concentration. The two-p k triple-layer site-binding model has been used to describe the electrical properties of the boehmite-water interface.
