a Proposed mechanism for the highly efficient MTBE dehydrogenative coupling to MTBE dimer and H2. b Illustration of the green transformation of methanol to EG and H2 developed by this work. The condensation of methanol and tert-butanol to form MTBE can be realized under mild conditions as has been extensively reported60,61.
