Abstract

Mejoras en el uso de metal en catalizadores soportados que contienen metal para celdas de combustible. Por ejemplo, la presente se refiere a métodos para dirigir y/o controlar la deposicion de metal sobre las superficies de sustratos porosos. La presente también se refiere a métodos para preparar catalizadores para celdas de combustible donde se deposita un primer metal sobre un soporte (por ejemplo, un soporte de carbono poroso) para proveer una o más regiones de un primer metal en la superficie del soporte, y se deposita un segundo metal en la superficie de las una o más regiones del primer metal. En general, el carácter electropositivo del primer metal (por ejemplo, cobre o hierro) es mayor que el carácter electropositivo del segundo metal (por ejemplo, un metal noble tal como platino) y el segundo metal se deposita en la superficie de las una o más regiones del primer metal por desplazamiento del primer metal. La presente también se refiere a sustratos tratados, estructuras precursoras del catalizador y catalizadores para celdas de combustible preparados por dichos métodos. La solicitud también se refiere al uso de catalizadores preparados segun se detalla aquí en celdas de combustible.Improvements in the use of metal in supported catalysts containing metal for fuel cells. For example, this refers to methods for directing and / or controlling the deposition of metal on the surfaces of porous substrates. This also refers to methods for preparing catalysts for fuel cells where a first metal is deposited on a support (eg, a porous carbon support) to provide one or more regions of a first metal on the surface of the support, and a second metal is deposited on the surface of the one or more regions of the first metal. In general, the electropositive character of the first metal (for example, copper or iron) is greater than the electropositive character of the second metal (for example, a noble metal such as platinum) and the second metal is deposited on the surface of the one or more regions of the first metal by displacement of the first metal. This also refers to treated substrates, catalyst precursor structures and catalysts for fuel cells prepared by said methods. The application also refers to the use of catalysts prepared as detailed herein in fuel cells.
