Effect Alkaline In Manganese Ore

Highlights a positive effect of alkali metal doping were observed in natural manganese ore (nmo).As electronic promoters, alkali promoters improve the reducibility of mn ions.Alkali metals enhance the activity of nmo in this order: li na rb k, cs.Nmo-k(cs)-0.07 could convert o-xylene (0.055 vol.%) into co 2 and h 2 o at 240 c.
