A carbonaceous heat source comprising metal oxides and methods for making such heat source are provided. The heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time produces virtually no carbon monoxide upon combustion. The heat source is prepared by pre-forming the carbon and binder materials into a desired shape, and then treating the shape with a sol containing metal oxide precursors. The metal oxide precursors are deposited in the pre-formed carbon shape. Further treatment converts the deposited metal oxide precursors into metal oxide.
