How to synthesize pure feitknechtite?

05 May 2019 1 6K Report

Hi there,

I would be very much interested in anyone´s experience concerning the synthesis of pure feitknechtite (β - MnOOH) from a birnessite precursor material.

I am familiar with the experiment from Elzinga 2011. Yet I would be happy if anyone could provide some more information on his or her experience, especially concerning the ratio of birnessite and Mn(II)aq, the reaction time used and the amount and purity of the resulting feitknechtite.

Thank you very much in advance for your help!
