Nano-structured carbon materials have various fascinating intrinsic properties such as high specific surface area, abundant pore structure, unique surface chemical properties, and can be coupled various inorganic materials to configure the carbon hybrid materials for application in emulsion catalysis. The characteristics and principles emulsified by solid particles, and the factors affecting the emulsion properties such as the emulsion type, emulsion droplet size, and emulsion stability were also introduced. The advances of emulsion catalysis technology derived from metal oxide, hydroxides, and carbon hybrid materials at home and abroad were also reviewed. Some problems presented in emulsion catalysis processes were also pointed out. It was believed that emulsion catalysis technology, especially using carbon hybrid materials as solid emulsifiers, was a prominently new catalysis technology and also one of the important directions of catalysis technologies in future.
