Figure 3From: Facile template-free synthesis of pine needle-like Pd micro/nano-leaves and their associated electro-catalytic activities toward oxidation of formic acid CVs of Pd catalysts obtained from different deposition methods in 0.5 M H 2 SO 4 solution. (1) Cyclic voltammetry deposition for 20 cycles (a), 35 cycles (b), 100 cycles (c) and (2) potentiostatic deposition at -0.2 V (d).Back to article page
