摘要
Abstract
Effect of Zr, Mo and Zn additives and physical milling on the properties of VPO catalysts have been investigated by means of XRD, XPS and FT-IR. Addition of Mo and Zn decreased the relative exposure of (200) plane, however, the relative concentration of the surface V4+ increased, therefore, the catalytic performance was increased. Addition of Zr appeared to increase the surface P/V ratios of the catalysts, and the element V on the surface was substiruted by Zr, so that Zr component showed insignificant promoting effect. Physical milling process increased the relative exposure of (200) plane, and the catalytic performance was enhanced.关键词
