Templated catalyst composition and associated method

摘要

A composition includes a templated metal oxide substrate having a plurality of pores and a catalyst material includes silver. The composition under H2 at 30 degrees Celsius, the composition at a wavelength that is in a range of from about 350 nm to about 500 nm has a VIS-UV absorbance intensity that is at least 20 percent less than a standard silver alumina catalyst (Ag STD). The standard alumina is Norton alumina, and which has the same amount of silver by weight.

1. A method, comprising: reacting a metal alkoxide with a silver composition and a templating agent to form a reaction product; hydrolyzing the reaction product to form a hydrolyzed reaction product; condensing the hydrolysed reaction product to form a templated substrate; and controlling the reacting, hydrolyzing and condensing step to control the silver loading of the templated substrate, and the silver loaded templated substrate having a VIS-UV absorbance intensity that is at least 20 percent less than a standard silver alumina catalyst, and which has the same amount of silver by weight at a wavelength in a range of from about 350 nm to about 500 nm, under H2 at 30 degrees Celsius.
