(A) Cyclic voltammograms of different catalysts in 0.25 M H2SO4 + 0.25 M HCOOH solution at a scan rate of 50 mV/s; (B) Chronoamperometric curves of different catalysts in 0.25 M H2SO4 + 0.25 M HCOOH solution at 0.1 V (vs. Ag/AgCl).
The catalysts in the two panels are: (a) Pd/RGO(with 0.4 mL TOP), (b) Pd/RGO(with 0.2 mL TOP), (c) Pd/RGO(with 0.6 mL TOP) and (d) Pd/XC-72.
