Moiré metal for catalysis

This study establishes a recipe for designing superior catalysts from the simple twist or stacking of formerly inactive catalytic metals, and proposes structural moir\'e as a promising nanoengineering method to tune surface properties for chemical adsorption. In a broad sense, the moir\'e engineering of surface chemical properties provides a physical way for the rational design of superior electrocatalysts for a variety of chemical reactions under different environmental conditions. This work brings the new concept of the ``moir\'e metal'', going beyond the previous moir\'e semiconductor, which paves the new direction for two-dimensional materials and heterogeneous catalysis.
