Propane dehydrogenation has been actively pursued as a promising method for propylene production to fill a growing supply–demand gap. Limited by the thermodynamics of this transformation, existing approaches face challenges of relatively low conversion and the need for a high temperature and low pressure. In this work, we report a photocatalytic approach that enables conversion beyond what can be achieved by conventional thermocatalysis. With sodium decatungstate and cobaloxime pyridine chloride as cooperative photocatalysts, we achieved a benchmark in propane dehydrogenation of 68.9% conversion and near-unity selectivity toward propylene production at room temperature and atmospheric pressure with hydrogen as the only byproduct. These results prove the concept of dehydrogenating propane for propylene production using light as the key energy input.

在环境条件下通过光催化进行高转化率丙烷脱氢


丙烷脱氢作为一种很有前途的丙烯生产方法，以填补不断扩大的供需缺口，一直被积极寻求。受这种转变的热力学限制，现有方法面临着相对低转化率以及需要高温和低压的挑战。在这项工作中，我们报道了一种光催化方法，该方法能够实现超越传统热催化所能实现的转化。以癸碳酸钠和氯化钴为配合光催化剂，我们在室温和大气压下实现了丙烷脱氢的基准，转化率为 68.9%，对以氢气作为唯一副产物的丙烯生产具有近乎统一的选择性。这些结果证明了使用光作为关键能量输入进行丙烷脱氢生产丙烷的概念。
