Methods of manufacturing nano-engineered carbon materials, such as carbon aerogels and carbon xerogels, and methods of manufacturing precursor solutions and sol-gels for making the same are provided. A method for manufacturing a precursor solution comprises programmed-addition of a cross-linking agent to a component mixture comprising a resorcinol compound. A method for manufacturing a sol-gel comprises subjecting a precursor solutions to at least one heat treatment. Methods for producing nano-engineered carbon materials from precursor solutions and sol-gels are also provided. Methods for using the nano-engineered carbon materials are also disclosed. The resulting nano-engineered carbon materials can be useful in a range of products including, supercapacitor applications, high-surface-area electrodes, fuel cells, and desalination systems.

Methods for producing precursor solutions and sol-gels for nano-engineered carbon materials and nano-engineered carbon materials created therefrom

Methods for making wet gels and dried gels therefrom are provided. The method for making a wet gel can include combining a hydroxybenzene compound, an aldehyde compound, and an additive to produce a reaction mixture. The additive can include a carboxylic acid, an anhydride, a homopolymer, a copolymer, or any mixture thereof. At least the hydroxybenzene compound and the aldehyde compound can be reacted to produce a wet gel. The reaction mixture can include about 10 wt % to about 65 wt % of the hydroxybenzene compound, about 5 wt % to about 25 wt % of the aldehyde compound, up to about 85 wt % of the carboxylic acid, up to about 40 wt % of the anhydride, up to about 40 wt % of the homopolymer, and up to about 40 wt % of the copolymer, where weight percent values are based on the combined weight of the hydroxybenzene compound, the aldehyde compound, and the additive.
