1. I have found in some paper : use of only MnO2 , no APS were used no specific anionic supplement were used. What could be the reason?
2. Use of MnO2 as the precursor oxide and using it with 1M or 0.2 M HCl, how can we deny the formation of MnCl2 and directly writing on the title formation of MnO2/Polyaniline composite?
Please explain these two things.
