Low-temperature selective catalytic reduction of NO with CO over A-Cu-BTC and AOx/CuOy/C catalyst

A-Cu-BTC(A = Fe, Ni, Co, Mn) was obtained using preassembled method with direct ion-exchange treatment and then used as precursor to acquire AO(x)/CuOy/C at 600 degrees C under nitrogen atmosphere. The characterization of the catalysts were performed and evaluated as the catalysts for selective catalytic reduction of NO with CO (CO-SCR). A-Cu-BTC was successfully applied in CO-SCR and had similar performance for catalytic denitration, while Fe-Cu-BTC didn't have a good performance. It was found that AO(x)/CuOy/C all performed outstanding catalytic effect for NO-CO reaction with the addition of A atoms than single CuOy/C. Better lower temperature catalyst performance of AO(x)/CuOy/C indicates that future design of mixed-node MOFs as precursor will have a promising future for denitration. The possible reaction mechanism about CO-SCR is discussed. These results provide that interesting MOFs and MOFs precursor as dual-function catalysts. (C) 2016 Elsevier B.V. All rights reserved.
