In a MFC Platinum were coated over Carbon electrode, but the electricity produced by Platinum caoated electrode was four times lower than that of plain carbon electrode.
Can you tell some more details about the carbon you used and the way you deposited the Pt? For example if the carbon is porous 1000 m2/g and you deposited Pt that clogged the pores orifices you might obtain lower currents.
If you can also add details regarding the method you used to test the catalytic behavior.
coating was done by chronoamperometry....
dipping the carbon electrode in Pt(Cl)3H6 for 2000sec.
as Pt is a good catalyst it should favour reaction by incresing current, but i am getting 4times lower than the plain one.
yes....... no doubt Pt is a good catalyst, good reducing agent, conductor as well, but guys my discussion is coating with Pt i should get better output of electricity but why am i geting lower output than plain electrode.....?
@is it because what Malachi noked saying might be the reason....?
can i get litreture or protocol on coating of catalyst.
@ oana catalina mocioiu, u mean its could be due to the interaction of Pt with other organic substances... can u plez make it clear, or add some article or litreture on this.
