Abstract
The direct conversion of tremendous greenhouse gas methane into various value-added chemical products or energy fuels is not only a concern associated with an economic interest but also related to environmental protection. However, neither industry nor academia has an effective or low-cost way to directly achieve this result. Herein, a high specific area (962 m2 g−1) porous organic polymer was designed and used as a substance to support catalytic active sites, including PdBr2, Pd(OAc)2, and well-dispersed AuPd bimetallic nanoparticles which were reduced via hydrogen flow. The as-synthesized catalysts (HNU-2 and HNU-3) can not only maintain the porous and stable structure of their pristine matrix but also show extremely high catalytic performance in methane direct transformation systems for preparing methanol derivative methyl trifluoroformate. Our simple strategy provides a complementary alternative to application of methane via an efficient one-step conversion procedure in order to reduce its impact on climate change and obtain value-added chemicals.
