The particle size distribution from the TEM analysis is given in Fig. S1a. It shows that the particles exhibited a distribution with the diameter varying from 150 to 240 nm and mainly concentrated on 200 nm. Meanwhile, the NPs prepared using the precursor in a molar ratio of CuCl2 : MgCl2 = 5 : 1, Cu2O-(5 : 1-Mg) NPs, show a BET surface area of 21.32 m2 g−1 and an average pore diameter of 12.01 nm. These results clearly indicate that introduction of Mg2+ ions into the Cu-precursor has an influence on the porous structure evolution of Cu2O NPs. |

The BET surface area and the average pore size of Cu2O-(sole CuCl2) are calculated to be 13.03 m2 g−1 and 7.29 nm. Meanwhile, the NPs prepared using the precursor in a molar ratio of CuCl2 : MgCl2 = 5 : 1, Cu2O-(5 : 1-Mg) NPs, show a BET surface area of 21.32 m2 g−1 and an average pore diameter of 12.01 nm.
