Abstract

Abstract: Spinel nano-Co3O4 was prepared by solid-state reaction at room temperature and investigated for selective catalytic reduction of NO x by NH3 (NH3-SCR). Although suffering from pore filling and plugging, treatment of this catalyst by SO2 showed novel promoting effect on NH3-SCR above 250°C. Bulk cobalt sulfate was observed over the sulfated Co3O4 with XRD, which would be an active component for NH3-SCR. The sulphated Co3O4 catalyst exhibited good resistance to SO2 (500ppm, 100ppm) and 10% H2O at a space velocity of about 25000h−1 at 300°C, as tested for 12h. [Copyright &y& Elsevier]
