Facile and template-free fabrication of mesoporous 3D nanosphere-like Mn_xCo_3−xO₄ as highly effective catalysts for low temperature SCR of NO_x with NH₃

Abstract

Mesoporous 3D nanosphere-like Mn_xCo_3−xO₄ was obtained <italic>via</italic> a template-free method. The formation mechanism was proposed and the synthesis conditions were carefully investigated. The operating temperature window was 75–325 °C when the NO_x conversion was above 80%.
