The present invention also relates to processes for the preparation of these materials and to the use of these materials in applications such as gas adsorption, mercury and gold capture, gas storage and as catalysts or catalyst supports.
Claims21
-51. (canceled)
A sulfur-doped carbonaceous porous material obtainable by a process comprising the steps of:
- i) preparing a sulfur-based polymer by reacting elemental sulfur with one or more organic crosslinking agents, wherein the organic crosslinking agent(s) comprises two or more carbon-carbon double bonds;
- and
- ii) carbonising the sulfur-based polymer of step (i) in the presence of at least one porosity enhancement agent.
A sulfur-doped carbonaceous porous material comprising:
- i) greater than or equal to 5 wt % sulfur;
- ii) a pore volume of greater than or equal to 0.75 cm3 g−1;
- and
- iii) a Brunauer-Emmett-Teller (BET) surface area of greater than or equal to 1250 m2 g−1.
