Described is a metal oxide support material containing nanoscaled iron-platinum group metal particles having a particle size in the range of 0.5 to 10 nm. At least 70% of the nanoscaled iron-platinum group metal particles are located on an outside surface layer of the metal oxide support material. The outside surface layer has an average volume of less than 50% based on the total volume of the metal oxide support material. Additionally, described is a process for preparation of metal oxide support materials containing nanoscaled iron-platinum group metal particles. Furthermore, described is the use of metal oxides containing nanoscaled iron-platinum group metal particles as catalysts, for example as a diesel oxidation catalyst for the treatment of exhaust gas emissions from a diesel engine.

Metal oxide support material containing nanoscaled iron platinum group metal

Process for passivating metallic surfaces, and a preparation suitable for implementing the process, comprising at least water, an acid, and a copolymer of functionalized (meth)acrylic esters, monomers containing phosphoric and/or phosphonic acid groups, monomers having COOH groups, and, if appropriate, further monomers. Copolymer which comprises said monomers.

Method of passivating metallic surfaces by means of copolymers having phosphoric acid and/or phosphonic acid groups

The present invention relates to a composition for coating metallic surfaces, comprising a binder component; a corrosion inhibitor polymer based on an ethylenically monocarboxylic and dicarboxylic acid and, if appropriate, further ethylenical monomers, a solvent component, and, if appropriate, crosslinkable components, and also pigment/filler components. The invention further relates to processes for its preparation and also to methods of coating a metallic surface using the composition, to coated metallic surfaces thus obtained, and to the use of the composition as a primer, particularly in coil coating or in atmospheric corrosion control. After drying, the applied layer preferably has a thickness of at least 3.1 &#x3bc;m and is therefore thicker than a typical pretreatment layer.
