Template‐free Electrosynthesis of Platinum Nano‐Cauliflowers for Catalysing Electron Transfer Reaction of Plutonium

A coupled‐oxido‐reductive multiple‐potentiostatic pulse strategy was developed to electrochemically prepare platinum‐nano‐cauliflowers (PtNCFs) on indium‐tin‐oxide (ITO) coated glass electrode. The mechanism of electrocrystallization was studied during the formation of PtNCFs on ITO. By virtue of th...

Zusammenfassung:A coupled‐oxido‐reductive multiple‐potentiostatic pulse strategy was developed to electrochemically prepare platinum‐nano‐cauliflowers (PtNCFs) on indium‐tin‐oxide (ITO) coated glass electrode. The mechanism of electrocrystallization was studied during the formation of PtNCFs on ITO. By virtue of that synthesis strategy, the PtNCFs/ITO surface could catalyse the quasi‐reversible electron transfer reaction of plutonium (Pu) (IV)/(III) redox couple in aqueous sulphuric acid solution compared to bare ITO.
