Re: redox reaction

Yes and No!
No because on the contrary H2O2 will oxidise Mn++ to Mn(III) and even MnO4- {Mn(VII)}
For Acid and neutral media the following half-reactions were found:

Volt	Results depending on pH, E and other species
1.77	Reduction:    H2O2  +  2H+  +  2e  =>   2 H2O
1.51	Oxidation:    Mn++  +  4H2O  =>   MnO4-  +  8H+  +  5e
1.23	Oxidation:    Mn++  +  2H2O  =>   MnO2  +  4H+  +  2e
1.15	Oxidation:    Mn++  =>   Mn+++  +  e
0.95	Oxidation:    Mn+++ + 2H2O =>   MnO2  +  4H+  + e

Yes:
However, the fuel pump of the German WII- V2-rocket was driven by KMnO4 and H2O2!. A very vigourous reaction in which a hot mixture of steam and oxygen was formed.
This is due to the catalytic action of KMnO4 on the decomposition of neutral or acidic H2O2 according to:

 Volt	 Results depending on pH, E and other species
1.77	Reduction:    H2O2  +  2H+  +  2e  =>   2 H2O
0.69	Oxidation:    H2O2  =>   O2  +  2H+  +  2e

It seems to me that a similar (MnO4- -catalysed) reaction might be possible in slightly alcaline media.
