Hello Jafar,

Commercial availability and location should be considered together (I suggest); therefore I recommend clay (or even waste ceramic powder) and any other mineral deposits such as limestone, dolomite (depending on availability in your region). Naturally, clay meets that spec but the rest require size reduction and calcination to expose as large surface as you need - pore size is a function of particle size.

Look around you, you would see more materials whose particle size / pore space you can alter easily to suit your demand.

Good luck.

Commercial porous materials (the pore size distribution can be chosen):

Anodic Aluminum Oxide

Ordered Mesoporous Carbons (CMKs)

You can search and buy them online.

Hi there,

We provide researchers with low-cost mild- and hard- anodized AAO templates, having different pore lengths and diameters. Contact: [email protected]
