Nonoxidative coupling of methane exhibits promising prospect in that it affords value-added hydrocarbons and hydrogen with high atom economy. However, challenge remains in direct, selective conversion of methane to more valuable hydrocarbons like olefins. The current work presents a catalyst with well-dispersed Ta atoms anchored by graphitic CN-supported phthalocyanine. Such a catalyst is able to convert methane selectively to ethylene and propylene at a relatively low temperature (350 °C). The conception of the active center and construction of the catalyst have been described, and the origins of the catalytic performance are discussed.
甲烷的非氧化偶联在提供具有高原子经济性的增值碳氢化合物和氢气方面展现出了广阔前景。然而，将甲烷直接、选择性地转化为更有价值的碳氢化合物（如烯烃）仍然面临挑战。当前的研究工作展示了一种由石墨型碳氮负载的酞菁锚定的、Ta原子分散良好的催化剂。这种催化剂能够在相对较低的温度（350℃）下将甲烷选择性地转化为乙烯和丙烯。文中描述了该催化剂活性中心的概念和结构，并讨论了其催化性能的来源。
