Patents by Inventor Michele Minana Lourseau

Michele Minana Lourseau has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Mono- or multi-metal microaggregates, a method for their preparation and their application in the catalysis of the photoreduction of water
    Patent number: 4745094
    Abstract: Mono- or multi-metal microaggregates in a monodisperse phase in a solid or liquid medium and of a size uniformly less than 5 nm. The microaggregates are obtained by irradiation of a metal salt or a mixture of salts, by means of an ionizing radiation source, comprising dissolving a metal salt or a mixture of metal salts, in an appropriate solvent, in the presence of an oxidizing radical scavenger, and a surfactant, a support or both a surfactant and a support, and then carrying out irradiation. The metal microaggregates are useful for catalysis of various reactions, in particular, the photoreduction of water.

  • Non-noble metal catalytic microaggregates, a method for their preparation and their application in the catalysis of the photoreduction of water
    Patent number: 4629709
    Abstract: The invention relates to metal microaggregates.The monodisperse of the invention are non-noble metal microaggregates in a monodispersed form in a solid or liquid medium and of a size uniformly less than 5 nm. They are obtained by irradiation of a metal salt or a mixture of salts, by means of an ionizing radiation source, by dissolving a non-noble metal salt or a mixture of metal salts, at least one of which is a non-noble metal, in an appropriate solvent, in the presence of an oxidizing radical scavenger and a surfactant and/or a support, and then by carrying out irradiation.Application is for catalysis of various reactions, in particular the photoreduction of water into hydrogen.
