a) Scheme of facet‐dependent selectivity of Cu2O catalysed propylene oxidation with O2. b1–b3) The conversion of C3H6 and selectivity of the C3H6 oxidation with O2 for propylene oxide, acrolein, and CO2 catalysed by: b1) c‐Cu2O, b2) o‐Cu2O, and b3) d‐Cu2O. b4) Specific reaction rate of the oxidation of C3H6 with O2 catalysed by c‐Cu2O, o‐Cu2O, and d‐Cu2O. c) The most stable structures of C3H6(a) species on Cu2O (111), (100), and (110) facet with the adsorption energy (Eads), C=C stretching frequency, and distance of C=C bond (d C=C). White, red, gray, green and pink balls behalf H, O, C, coordinatively unsaturated Cu, and coordinatively saturated Cu, respectively. Reproduced with permission.3
