I find DMF seems not stable below -2 V vs SHE. The decomposition products of DMF seems electroactive. Is anyone come across similar phenomenon? Or can anyone suggest some relative literatures?
I usually filter the commercial DMF over neutral alumina to possibly get rid of any decomposition products like dimethylamine that might be electroactive ...
Using GC electrode and TBAPF6 as an electrolyte, the potential window of DMF I would say is between -2 V and +1.5V vs SCE ..
