Methane represents one of the most abundant carbon sources for fuel or chemical production. However, remote geographical locations and high transportation costs result in a substantial proportion being flared at the source. The selective oxidation of methane to methanol remains a grand challenge for catalytic chemistry due to the large energy barrier for the initial C–H activation and prevention of overoxidation to CO2. Indirect methods such as steam reforming produce CO and H2 chemical building blocks, but they consume large amounts of energy over multistage processes. This makes the development of the low-temperature selective oxidation of methane to methanol highly desirable and explains why it has remained an active area of research over the last 50 years.

甲烷在水中氧化成甲醇

甲烷是燃料或化学品生产中最丰富的碳源之一。然而,偏远的地理位置和高昂的运输成本导致很大一部分在源头燃烧。由于初始 C-H 活化和防止过度氧化成 CO 2的巨大能量障碍,甲烷选择性氧化成甲醇仍然是催化化学的巨大挑战。蒸汽重整等间接方法产生 CO 和 H 2化学构件,但它们在多阶段过程中消耗大量能量。这使得将甲烷低温选择性氧化成甲醇的开发非常受欢迎,并解释了为什么它在过去 50 年中一直是一个活跃的研究领域。
