Abstract
The present invention relates to novel sulfur-doped carbonaceous porous materials. 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.
Claims10
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) carbonizing the sulfur-based polymer of step (i) in the presence of at least one porosity enhancement agent;
- wherein the sulfur-doped carbonaceous porous material comprises greater than or equal to 10 wt % sulfur;
- and
- the sulfur-doped carbonaceous porous material comprises both micropores and mesopores.
