Studies on chromia/zirconia catalysts. 2. ESR of chromium species

The characterization of CrO{sub x}/ZrO{sub 2} samples (Cr content 0.05 to 6 wt%) by means of ESR spectroscopy is reported. On samples heated in O{sub 2} at increasing temperatures up to 1173 K, the presence of Cr(V) is detected by ESR. Its concentration (Cr(V) ions nm{sup {minus}2}) is found to incr...
