SpletPB is a low-cost material that upon reduction can be re-oxidized by O 2 in air at ambient temperature and pressure (Fig. 1b). We nd that MBs equipped with PB electrodes achieve net energy recovery efficiencies of 18–33%, values comparable to those obtained with Ag 2O/Ag electrodes.22 To prepare PB electrodes, we electrochemically reduced SpletIf we are reducing copper 2+ to solid copper, the standard reduction potential is +.34 volts. If we are reducing zinc 2+ to solid zinc, the standard reduction potential turns out to be -.76 volts. The more positive value, the more likely the substance is to be reduced, so obviously +.34 is more positive than -.76.
