Polyvinylpyrrolidone adsorption effects on the morphologies of synthesized platinum particles and its catalytic activity

Flower-like Platinum micro-structures were synthesized from different concentration of the PVP using solvothermal method. At 5.0×10−3 mmol of PVP, well-defined flower-like pattern consists of triangular petals radiating from the centre were produced whereas larger flower network developed at higher...

Description
Summary:Flower-like Platinum micro-structures were synthesized from different concentration of the PVP using solvothermal method. At 5.0×10−3 mmol of PVP, well-defined flower-like pattern consists of triangular petals radiating from the centre were produced whereas larger flower network developed at higher PVP concentration. High degree of crystallinity was obtained upon each increment of PVP. The well defined flower like pattern synthesized using 5.0×10−3 mmol PVP exhibit the highest catalytic activity and stability towards electro-oxidation of formic acid.
