                         room temperature has gained increased attention given its 
                         relevance, from propulsive systems to metal-O2 conversion 
                         batteries. This study describes, by a rational design of 
                         experiment, the influence of selected parameters such as: pH, 
                         initial concentration of K2CO3, precipitate aging, precipitate 
                         washing, and thermal treatment for the hydrotalcite 
                         co-precipitation, characterizing it for each synthesis variable. 
                         The results show that hydrotalcites can efficiently be converted 
                         in Co-Mn-Al spinels and as a result, a new highly active 
                         Co2Mn0.5Al0.5O4 spinel oxide was synthesized after thermal 
                         treatment. Its activity and mechanical resistance were tested in a 
                         micro-thruster reactor where it showed total decomposition (> 98%) 
                         of H2O2 and in a Li-O2 battery, with increased cyclability, been 
                         able to reduce the charging potential in ~200 mV. These 
                         encouraging results enhance the importance not only of this class 
                         of material, but also, the importance of robust synthesis
