NH3-selective catalytic reduction performance of a new type of Cu@ZIF-7 catalyst
Source abstract
Abstract
To achieve a selective catalytic reduction of nitrogen oxide (NOx) in a wide temperature range and avoid the secondary pollution of commercial catalysts, a new type of highly active catalyst Cu@ZIF-7 was synthesized. X-ray diffraction, x-ray photoelectron spectroscopy, and scanning electron microscopy were performed to analyze the morphological characteristics of Cu@ZIF-7. The effects of Cu load capacity, impregnation time, impregnation temperature, catalyst dosage, and reaction temperature on NOx removal efficiency were also investigated. Cu@ZIF-7 maintained a NOx removal efficiency of >90% in a temperature range of 250–400 °C. Finally, the stability, sulfur, and water resistance of Cu@ZIF-7 were investigated, and the NOx conversion mechanism was inferred through in situ diffuse reflectance infrared Fourier transform spectroscopy and references.
