开发用于烃和醇的选择性好氧氧化以利用大气空气或分子氧产生更多功能性化合物(醛、酮、酸或酯)的有效系统是化学工业的巨大挑战。在这里,我们报告的合成钯纳米粒子支持在新型纳米多孔氮掺杂碳,和他们的令人印象深刻的性能在控制氧化的烃类和醇类与空气。就催化活性而言,这些催化剂在相同的反应条件下提供比大多数报道的钯催化剂高得多的周转频率(对于烃氧化高达863次周转/小时,对于醇氧化高达~ 210,000次周转/小时)。该工作为环境空气和可回收钯催化剂在精细化工生产中的高活性应用提供了巨大的潜力。
The development of efficient systems for selective aerobic oxidation of hydrocarbons and alcohols to produce more functional compounds (aldehydes, ketones, acids or esters) with atmospheric air or molecular oxygen is a grand challenge for the chemical industry. Here we report the synthesis of palladium nanoparticles supported on novel nanoporous nitrogen-doped carbon, and their impressive performance in the controlled oxidation of hydrocarbons and alcohols with air. In terms of catalytic activity, these catalysts afford much higher turnover frequencies (up to 863 turnovers per hour for hydrocarbon oxidation and up to ~210,000 turnovers per hour for alcohol oxidation) than most reported palladium catalysts under the same reaction conditions. This work provides great potential for the application of ambient air and recyclable palladium catalysts in fine-chemical production with high activity.
