The solution, which was composed of 8% nonionic surfactant, 1% α-lipoic acid, and water, was assessed by visual inspection. All these demonstrate that Pd micro/nano-leaves possess an fcc structure.Figure 2 XRD patterns of Pt nanoparticles electrodeposited for 20 cycles (a), 50 cycles (b), 100 cycles (c), 200 cycles (d). Inspired by their intriguing structure, Pd nanoparticles were tested as electrocatalysts. The CMC of α-lipoic acid was given by the breakpoint of the surface tension curve, namely corresponding to 80 mM. Over this concentration, micellar colloids should be present in dynamic equilibrium with α-lipoic acid monomers in the solution.
