MoO 3 is a promising supercapacitor electrode material despite its moderate specific capacitance and cycling stability. The work featured on the Front Cover shows that the surface functionality of MoO 3 can be modified selectively by tuning the hydrogen peroxide concentration, producing peroxide (O 2 2− ) and superoxide (O 2 − ) anions. Meanwhile, bearing different chemical environment at the surface, the inter‐atom bonding of MoO 3 was altered. This approach of in situ modification of the MoO 3 surface enables enhanced specific capacitance and cycling stability. More details can be found in the Communication by P. S. Lee, et al. on page 403 in Issue 6, 2015 (DOI: 10.1002/cnma.201500045).
