%X The non-oxidative dehydrogenation (NOD) of methanol in the gas-phase is a H<sub>2</sub>-efficient route for the synthesis of the sustainable fuel additive dimethoxymethane (DMM). Overcoming the thermodynamic limitation and suppression of by-products are the central challenges. Therefore, in this work, a new catalyst and reactor system was developed to improve catalytic activity, DMM selectivity, stability, and induction period, as well as to expand the knowledge about structure-activity relationships. To achieve this, new bifunctional catalysts with dehydrogenative and Lewis-acidic functionality were systematically developed based on the previously established benchmark Cu/Hβ catalyst.  Initially, the Cu/Hβ catalyst was investigated for its reproducibility and storage properties, establishing a new reproducible benchmark for catalytic performance (DMM selectivity: 58.1 ± 0.4
