Synthesis of carbon molecular sieve microspheres via amino phenolic resin as precursor formed from in-situ reaction composite micelles

The carbon molecular sieve microspheres (CMSm) is one kind of porous carbonaceous materials. Owing to its high surface area and stability, CMSm have been attracted immense attention in various fields. In this study, the CMSm with tunable pore structure has been synthesized via self-assembling, in-situ reaction and soft-templating method in aqueous system. Meanwhile, the influence of carbonization temperature, heating rate, surfactant content and the amount of pore-forming agent (1, 3, 5-trimethylbenzene) on the morphology and pore properties of CMSm were studied. The result of nitrogen adsorption/desorption analysis indicates that the volume of the micropores increases as carbonization temperature increases, and generally decreases as the heating rate increases. The amount of surfactant and pore-forming agent have little influence on the volume of the micropores. It is also found that the CMSm have good hydrogen storage performance.
