Abstract

original image

Peroxide power: Neutral solutions of H2O2 can be produced directly and safely from O2 and H2 by using a fuel cell reaction. The most active and efficient cathode is a vapour-grown carbon fibre (VGCF) electrode coated with Co-tetraphenylporphyrin (0.05 wt %) on VGCF (2 mg cm−2). A maximum concentration of 13.5 wt % (4.0 M) H2O2 is obtained under optimized conditions at 278 K.
