Direct catalytic conversion of methane to methanol with O has been a fundamental challenge in unlocking abundant natural gas supplies. Metal-free methane conversion with 17% methanol yield based on the limiting reagent O at 275 °C was achieved with near supercritical acetonitrile in the presence of boron nitride. Reaction temperature, catalyst loading, dwell time, methane-oxygen molar ratio, and solvent-oxygen molar ratios were identified as critical factors controlling methane activation and the methanol yield. Extension of the study to ethane (C2) showed moderate yields of methanol (3.6%) and ethanol (4.5%).
将甲烷与氧气直接催化转化为甲醇一直是释放丰富天然气供应的一项根本性挑战。在氮化硼存在的情况下，使用近超临界乙腈在275°C实现了基于限量试剂氧气的无金属甲烷转化，甲醇产率为17%。反应温度、催化剂负载量、停留时间、甲烷-氧气摩尔比和溶剂-氧气摩尔比被确定为控制甲烷活化和甲醇产率的关键因素。将该研究扩展到乙烷（C₂）显示甲醇（3.6%）和乙醇（4.5%）的产率适中。
