Abstract
La presente invención se refiere a composiciones catalizadoras de la oxidación de diésel y artículos catalizadores, en donde las composiciones y los artículos incluyen una pluralidad de nanopartículas del grupo del platino sustancialmente en forma totalmente reducida, en donde las nanopartículas tienen un tamaño de partícula media de aproximadamente 1 a aproximadamente 10 nm y al menos aproximadamente el 90% de las nanopartículas tienen un tamaño de partícula de +/- aproximadamente 2 nm del tamaño de partícula medio. Estas composiciones también pueden incluir un material de óxido de metal refractario, en donde las nanoparticulas y el material de óxido de metal refractario se pueden combinar dentro del mismo revestimiento sobre un sustrato o se pueden aplicar secuencialmente sobre un sustrato. Las nanopartículas pueden estar de modo ventajoso sustancialmente libres de haluros, metales alcalinos, metales alcalinotérreos, compuestos de azufre, y compuestos de boro. Los métodos de preparación y uso de tales composiciones y artículos catalizadores (por ejemplo, para el tratamiento de corrientes de gases de escape diésel) también se proporcionan en la presente.
