Heterogeneous catalyst of porous anodic aluminum oxide with Al substrate supported metal nanoparticles

Porous Anodic Aluminum Oxide as an Efficient Support for Ruthenium-Catalyzed Aerobic Oxidation of Alcohols and Amines

“…As shown in Figure , the structure of porous AAO is composed of a compact arrangement of six-membered extended units having stretched semicylindrical pores, which are closed by the bottom oxide layer . Several studies about the role of porous alumina in catalysis demonstrated higher efficiency than the bulk catalyst. , Due to its insulating nature, the surface of AAO is liable for various chemical changes in acidic media . This drawback can be controlled by the AAO surface modification.…”

Birefringence in anodic aluminum oxide: an optical method for measuring porosity

“…Anodic aluminum oxide (AAO) films are widely applied in different fields of science and technology. They can be used as membranes, 1 templates for the preparation of nanowires 2 and nanotubes, 3 catalyst carriers, 4 substrates for gas sensors, 5 biosensors, 6 alternative energy sources, 7 and accumulators. 8 Special attention should be paid to the optical applications of AAO films, such as photonic crystals, 9,10 filters with a voltagecontrolled wavelength, 11 an additional layer to increase the efficiency of the solar panels, 12 a part of the light source, 13 and templates for metamaterials based on ordered arrays of metal nanorods.…”

Influence of anodization parameters on film thickness and volume expansion of thick- and large-sized anodic aluminum oxide film

“…They reported that Pd-based AAO catalyst exhibited higher productivity than spherical Pd/Al 2 O 3 catalyst due to the advantages in mass/heat transfer and con nement effect of cylindrical pores. Some relevant research groups [3][4][5][6][7] and our group [8][9][10][11] applied the novel MMC catalyst support to various elds such as hydrogenation reaction [3], steam reforming of methanol [4], Suzuki cross-coupling reaction [5], Fischer-Tropsch synthesis [6], VOCs combustion [7] and steam reforming of methane [11].…”
