Introduction to Tafel Plot/Equation, Butler-Volmer Equation and Foot-of-Wave-Analysis (FOWA)

[@carlostma643]

Very helpful. Got a lot out of this. Never seen the symmetry factor explained like that.

[@bupekasanya6161]

Very insightful and straightforward

[@aurorali323]

This is great. I finally understand now.

I know exactly how you feel, when we teach we are also remembering the struggle to understand - M

I want to have a video derivation of Tafel and Butler-Volmer equations. Also, this is really helpful! Thank you for making this video

[@zimmerpeacock9703]

Definitely will

[@sanjaychandra7710]

This is useful. More detailed explanation of the same for the case of corrosion would be helpful

[@zimmerpeacock9703]

I would like to do more on corrosion :)

[@MuhammadBilal-dj8ko]

thanks a lot, really helpful

Hi Zimmer, should tafel plot be extracted from CV in CO2 reduction reaction? in this case alpha will be 0.8?

Very interesting topic !
Many students find this very difficult to understand

[@zimmerpeacock9703]

Thank you - I agree, I think the topic is taught in isolation from the rest of the topics, so what I want to do is show how everything is connected. thank you for the feedback

Thank you for the video. I have some electrochemical data, I was able to do a fit of the Tafel equation; however, I noticed my alphas were very small, I think around 0.02, any suggestions?

[@zimmerpeacock9703]

You may have made one mistake, for example where something is 10 and you have put it in as 100. This happens a lot :)

Thank you Zimmer

[@heeralalsoni9307]

very useful session
can you make video on derivation of Buttler Volmer equation and Tafel equation

[@zimmerpeacock9703]

I do read these comments and I do put them on the to-do list, thank you -

Hi, can you do calculation from CV data for HER reactions, like tafel slope, ipc and ipa etc if possible

[@j.t.4652]

Thank you for the video! Could you go deeper into the Tafel plot and also the weaknesses of this evaluation method? In my group some people have raised concerns about the meaningfulness of Tafel plots.

hello sir,
can you explain of application of curve fitting for tafel to bulter volmer equation from LSV curve?

I will try to cover in a webinar this week - www.zimmerpeacocktech.com/2023/03/17/zp-developers-zone-8-am-london-23-march-2023/

How can we find different techniques to calculate tafel slope

Can you introduce three different overpotentials

So sorry, not quite understanding the question, can you re-phrase please?

@@zimmerpeacock9703 Hi, sorry for the confusion. I am confused by the differences between surface overpotential, ohmic overpotential, and mass transfer overpotential
