Catalytically Active Gold Supported On Thermally Treated Nanoporous Supports

Номер: US20100273091A1
Принадлежит: 3M Innovative Properties

The present invention provides technology for controlling, or tuning, the catalytic activity of gold provided upon nanoporous supports such as those derived from nanoparticulate titania. It has been discovered that the nature of the surfaces of the nanoparticles used to support a nano-metal catalyst, such as catalytically active gold, has a profound effect upon the catalytic properties of the supported catalyst. The support surface may be altered as desired to control the activity of the gold. The present invention teaches how thermal treatment of nanoparticulate media incorporated into a nanoporous support prior to deposition of catalytically active gold dramatically suppresses the ability of a resultant catalyst system to oxidize hydrogen. Yet, the system still readily oxidizes CO.

Catalytically active gold supported on thermally treated nanoporous supports

Номер: US0008137750B2

The present invention provides technology for controlling, or tuning, the catalytic activity of gold provided upon nanoporous supports such as those derived from nanoparticulate titania. It has been discovered that the nature of the surfaces of the nanoparticles used to support a nano-metal catalyst, such as catalytically active gold, has a profound effect upon the catalytic properties of the supported catalyst. The support surface may be altered as desired to control the activity of the gold. The present invention teaches how thermal treatment of nanoparticulate media incorporated into a nanoporous support prior to deposition of catalytically active gold dramatically suppresses the ability of a resultant catalyst system to oxidize hydrogen. Yet, the system still readily oxidizes CO.

Selective Oxidation of Carbon Monoxide Relative to Hydrogen Using Catalytically Active Gold

Номер: US20090011293A1
Принадлежит: 3M Innovative Properties Co

The present invention provides technology for controlling, or tuning, the catalytic activity of gold provided upon nanoporous supports such as those derived from nanoparticulate, crystalline titania. In some aspects of practice, the surface of nanoparticulate media incorporated into a catalyst system of the present invention is provided with chemical modifications of the surface that dramatically suppress the ability of the resultant catalyst system to oxidize hydrogen. Yet, the system still readily oxidizes CO. In other words, by selecting and/or altering the nanoparticulate surface via the principles of the present invention, PROX catalysts are readily made from materials including catalytically active gold and nanoparticulate media. Additionally, the nanoparticulate support also may be optionally thermally treated to further enhance selectivity for CO oxidation with respect to hydrogen. Such thermal treatments may occur before or after chemical modification, but desirably occur prior to depositing catalytically active gold onto the support incorporating the nanoparticles.
