摘　　要：乙苯脱氢制苯乙烯是工业上十分重要的反应。以纳米碳材料为催化剂,催化乙苯脱氢制苯乙烯是纳米碳材料领域近年来的研究热点之一。相比于传统的金属氧化物催化剂,纳米碳材料既可以在较低温度下高活性地催化乙苯氧化脱氢,也可以高选择性地催化乙苯直接脱氢,且反应过程中无需通入水蒸气,极大地提高了能源利用效率,具有较大的发展潜力。综述了近年来纳米碳材料催化乙苯脱氢制苯乙烯的研究进展,主要包括纳米碳材料的结构和表面化学性质、纳米碳催化剂的研究进展、催化乙苯脱氢反应机理等方面,同时总结了该领域存在的挑战并对前景进行了展望。Dehydrogenation of ethylbenzene to styrene is one of the most important processes in industry.Using emerging nanocarbons as catalysts is one of the most active research directions in this process.Compared with commercial iron oxide catalysts,nanocarbon catalysts exhibit high activity in the oxidative dehydrogenation of ethylbenzene at lower temperature,and high selectivity in the direct dehydrogenation of ethylbenze at steam-free condition,which is meaningful for energysaving.This review highlights recent progresses in catalytic dehydrogenation of ethylbenzene to styrene by nanocarbon catalysts. The structure and surface properties of nanocarbons,the preparation procedure and performance of nanocarbon catalysts and reaction mechanisms are systemically introduced.Finally,the current challenges and future perspectives for the industrial application of nanocarbon catalysts in this area are also presented.
