POROUS COMPOSITE METAL OXIDE, CATALYST USING THE SAME, AND METHODS FOR PRODUCING THE POROUS COMPOSITE METAL OXIDE AND THE CATALYST |
摘要 |
A porous composite metal oxide, including a mixture of first ultrafine particles containing alumina and second ultrafine particles containing zirconia, wherein the first ultrafine particles and the second ultrafine particles are uniformly dispersed in such a way as to satisfy a condition that standard deviations of content ratios (% by mass) of all metal elements contained in the porous composite metal oxide at 0.1% by mass or more are each 10 or less, the standard deviations being obtained by measuring content ratios of the metal elements at 100 measurement points within a minute analysis region of 20 nm square by energy dispersive X-ray spectroscopy using a scanning transmission electron microscope equipped with a spherical aberration correction function. |
