Abstract:
La solicitud se refiere a una mezcla estable que comprende partículas modificadas en la superficie, que se obtienen haciendo reaccionar partículas de óxido de metal o no metal o de óxido de semimetal con un compuesto que comprende silicio y que tiene un radical oxi, alcoxi y/o hidroxi; un solvente; un tensoactivo o una de sus mezclas. También se plantea un proceso para producir una partícula modificada en la superficie, poniendo en contacto la mezcla, en una etapa posterior con CO2. También se reivindica el uso de dichas partículas modificadas en la superficie.
