But the mentioned methods displayed some disadvantages because complex starting materials was required and obtain smaller quantity of the product.
Na2CO3, γ-Al2O3 and MgO, were used as starting materials.
Mixture of starting materials was produced according to desired condition by ball-milling for 20 h in ethanol solvent with YZT balls.

Thus, natural materials available and accessible in large quantities are suitable to this aim.
Materials and methods The peat sample from Xinyuan city of Liaoning Province of China was dried in an oven at 100 oC for 24h and then was sieved using a British Standard 80 mesh sieve to maintain a uniform particle size.

We use a Sieverts type volumetric apparatus to investigate the material properties,including P-C-T properties and hydriding/ dehydriding kinetics under different conditions.
Based on the results obtained, the feasibility of using the material for gas separation purpose was discussed.
