Abstract
The invention provides methods of preparing carbon/sulfur composites. In certain embodiments, the composites comprise multidimensional carbon tubular and/or spherical networks loaded with elemental sulfur, as well as compositions comprising such composites.
Claims20
A method of preparing a carbon/sulfur composite, wherein the composite comprises multidimensional carbon tubular or spherical networks associated with elemental sulfur, the method comprising:
- contacting (i) a first layer comprising at least one soluble organic compound and a salt solution and (ii) a second layer comprising a gel, a salt solution, and at least one sulfide source, wherein the second layer is substantially free of oxygen gas at the time of contacting;
- and
- directly exposing the first layer to an atmosphere comprising oxygen gas;
- whereby the composite is formed once the first layer and the second layer at least partially mix and react.
