Synthesis of hydrofluoroolefins by vapor phase catalytic dehydrofluorination of hydrofluoroalkanes is one of the most promising ways, and the process is simple and cost - effective. Developing the catalysts with high activity and good coking resistance is the key of this technology. In this paper, research advance on several main vapor phase dehydrofluorination catalysts including aluminum - based catalysts, chromium - based catalysts and ac- tivated carbon catalysts has been reviewed, and the major exisiting problem and research direction in the field of ca- talysis are outlined.
