摘要
The present invention relates to mixed metal oxide (MMO1) catalysts. MMO1 catalyst performance is improved with a sub-monolayer deposition of Te onto its surface by vapor deposition. The selectivity to acrylic acid improved by approximately 6% and the acrylic acid yield by 3%, absolute. Applying a similar Te loading onto MMO1 by wet impregnation methods did not improve catalytic performance. Post treatment of the Te vapor deposited MMO1 catalyst with oxygen at elevated temperatures gave improved catalytic performance when compared to a corresponding sample treated with an inert gas at the same elevated temperatures.
