What is XPS Analysis of DeNOx Catalysts about?
The study employs X-ray photoelectron spectroscopy (XPS) to analyze the surface composition of DeNOx catalysts after exposure to flue gas from slag tap furnaces. The analysis reveals the presence of various elements, including Ca, Si, O, S, As, P, and N, with challenges in determining the oxidation state of arsenic. The findings suggest that the quality of flue gas significantly impacts catalyst deactivation, particularly noting differences in performance between catalysts containing molybdenum and tungsten
