What is the reason for current dropping in OER , LSV curve?

I tried four trials of the same Copper Phosphides sample in Alkaline medium ( 0.5M KOH) with Hg/HgO reference electrode and Pt as counter electrode. I used 0.001 V/s scan rate for first three...

Fatsah Moulai

thank you habib muhammad

Amine Achour

I think it will be for binary/ternary transition metal oxide modified at the moleculair level ,

Emile Haye

According to the plenary talk at the last IseeCap Conference, MXenes will certainly take a huge place in the next supercapacitor materials, in addition to transition metal oxide.

The use of ionic liquid as electrolyte seems to be promising also.

thank you

Amine & Emile

Guerra Abdelouadoud

Coupling metal oxide with metal nitride seems to be promising

Thats a good way to the future Abdou if we collaborate with Amine & Emile in this project.
