Abstract

The invention provides a preparation method of a through hole type alumina catalyst carrier. The preparation method comprises the following steps: performing a selective adsorption reaction on a porous layer and a shielding layer by gamma-chloropropyltrimethylsilane, performing subsequent an alkaline corrosion reaction, effectively removing the shielding layer at the bottom of a pore channel, andperforming a chemical replacement reaction to remove an aluminum base material, thereby obtaining the through-hole type aluminum oxide catalyst carrier.

Description

technical field

[0001] The invention relates to a through-hole alumina catalyst carrier and a preparation method thereof, which belongs to the fields of electrochemistry and catalysts, and is especially suitable for the field of catalyst carriers and a preparation method thereof.

[0002] technical background

[0003] Aluminum or aluminum alloy anodizing refers to the process of immersing aluminum or aluminum alloy in a suitable electrolyte as an anode for electrification, and forming an oxide film (Al2O layer) on the surface of aluminum or aluminum alloy. The existence of this layer of oxide film can improve the corrosion resistance of aluminum alloy. At the same time, with the help of the special structure of the oxide film and the later treatment process, for example, the anodic oxide film can also be combined with surface painting and other further treatments to make the substrate more harsh. To achieve better protection in the environment, or to decorate aluminum and alu...
