Abstract

This study described a template-free method for the synthesis of hierarchically macro-mesoporous Mn-TiO catalysts. The promoting effect of Mn doping and the hierarchically macro-mesoporous architecture on TiO based catalysts was also investigated for the selective reduction of NO with NH . The results show that the catalytic performance of TiO based catalysts was improved greatly after Mn doping. Meanwhile, the Mn-TiO catalyst with the hierarchically macro-mesoporous architecture has a better catalytic activity than that without such an architecture.
