Zusammenfassung:	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. Une composition comprend un substrat doxyde métallique structuré comportant une pluralité de pores et un matériau catalyseur comprend de largent. La composition sous H2 à 30 degrés Celsius, la composition à une longueur donde qui se trouve dans une plage denviron 350 nm à environ 500 nm, comporte une intensité dabsorbance VIS/UV qui est au moins de 20 % inférieure à celle dun catalyseur argent-alumine standard (Ag STD). Lalumine standard est de lalumine Norton, qui présente la même quantité dargent en poids.
