ABSTRACT Metallene has been widely considered as an advanced electrocatalytic material due to its large specific surface area and highly active reaction sites. Herein, we design synthesize ultrathin rhodium metallene (Rh ML) with abundant wrinkles supply surface‐strained Rh sites for driving acetonitrile electroreduction ethylamine (AER). The electrochemical tests indicate that ML shows yield rate of 137.1 mmol g cat −1 h in acidic solution, stability lasting up 200 h. Theoretical calculations reveal wrinkle‐induced compressive strain not only a lower energy barrier the rate‐determining step but also facilitates desorption process compared wrinkle‐free commercial black. assembled electrolyzer bifunctional electrolysis voltage 0.41 V at 10 mA cm −2 , enabling simultaneous production hydrazine waste treatment. Furthermore, hybrid zinc–acetonitrile battery can effectively drive this achieve dual AER process. This study provides guidance improving catalytic efficiency atoms two‐dimensional materials, well synthesis technology series‐connected battery–electrolyzer systems.
