Activated carbon-metal organic framework composite materials with enhanced gas adsorption capacity and process for the preparation thereof

A process for the preparation of an activated carbon-metal organic framework composite material with enhanced gas adsorption capacity and having activated carbon from 1 wt % to 4 wt %, wherein the said process comprising the steps:

• a. dissolving an organic ligand in ethanol;
• b. dissolving a metal salt in the water;
• c. mixing the solution as obtained in step (a) with solution as obtained in step (b) followed by stirring at temperature ranging from 298K to 308K for a period ranging between 10 to 50 min;
• d. transferring the reaction mixture as obtained in step (c) into an autoclave and further adding activated carbon in the range 1 to 4 wt % in respect of weight of product followed by heating at temperature ranging between 383K and 423K for a period ranging between 15 to 20 hours to obtain an activated carbon-metal organic framework composite material.
