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 onestep conversion procedure in order to reduce its impact on climate change and obtain value-added chemicals.

1 Introduction Greenhouse gas methane has attracted considerable attention nowadays because it can be used as an industrial hydrocarbon source to produce necessities, thereby reducing its own impact on climate warming and the dependence of industrial development on petroleum [1–4].

the dominant integral of natural gas, biogas, and shale gas but also a significant component of flammable ice [5–7]. The total volume of methane gas situated in some particular sea-floor and permafrost areas, i.e. the South China Sea, is about 20,000 trillion m3 which is double as other traditional carbon resources [8–10]. Additionally, the successful trial exploitation of methane hydrate drives it as a more affordable source to replace crude oil for producing various valueadded chemical products, and more available feedback for energy fuels, which is also due to its topmost mass heat of 56 kJ g−1 among all the hydrocarbons [11, 12]. However, methane hyd
