Facile Preparation of High Performance Low Concentration HCHO Degradation Catalyst from Waste Li-MnO2 Batteries

The recycling and utilization of lithium-ion batteries has received a lot attention. use recycled waste lithium-manganese to degrade formaldehyde contaminated gas by adsorption is certainly killing two birds with one stone. In this paper, efficient catalysts capable degrading were obtained using button being discharged different levels then recovering the cathode material simple method labelled as LixMnO2 (x = 0.00; 0.25; 0.50; 0.75; 1.00). fully Li1.00-MnO2 degraded at nearly 100% (less than 0.1 ppm) within 24 h room temperature, which twice degradation rate undischarged material. high efficiency attributed continuous doping Li+ discharge proceeds conversion Mn(IV) Mn(III), so lattice gap, defects, surface oxygen species specific area catalyst increase. And involved in increases. catalytic activity for gradually increased discharge, promoting effect. low concentrations was close h. This study provides an attractive approach converting lithium battery electrode materials into improve indoor environment.
