Selective methane conversion to alcohol derivatives remains an open challenge. Here, bimetallic catalyst, AuPd@ZIF-8, has been synthesized and demonstrated as an excellent catalyst in the presence of H₂O₂ and O₂ under mild condition. Specifically, the yield for liquid oxygenated and methanol are 83.0 and 21.7 mmol g_AuPd⁻¹ h⁻¹, with selectivity up to 89.5% and 21.9%, respectively. This high productivity may be due to the synergistic effect between AuPd nanoparticles and ZIF-8 framework. Oxygen-based isotopic tests reveal that oxygen serve as oxidants for this oxidation process. Methyl hydroperoxide is the primary product at early stage, which can be further oxidized.

选择性地将甲烷转化为醇衍生物仍然是一个开放的挑战。在这里，双金属催化剂 AuPd@ZIF-8 已被合成，并在温和条件下在 H ₂ O ₂和 O ₂存在下证明是一种优异的催化剂。具体而言，液态氧化和甲醇的产率分别为83.0和21.7 mmol g _AuPd ^-1 h ^-1，选择性分别高达89.5%和21.9%。这种高生产率可能是由于 AuPd 纳米粒子和 ZIF-8 框架之间的协同作用。基于氧的同位素测试表明，氧作为该氧化过程的氧化剂。甲基氢过氧化物是早期的初级产物，可进一步氧化。
