Claim 0:
1. A catalyst comprising:
a silica core having an outer surface;
a mesoporous silica shell having an outer surface and an inner surface with the inner surface being inside the outer surface of said mesoporous silica shell proximate to and surrounding the outer surface of said silica core, wherein the outer surface of the mesoporous silica shell has openings leading to pores within the mesoporous silica shell which extend toward the outer surface of said silica core; and
catalytically active metal nanoparticles positioned within the pores proximate to said core, wherein said catalytic metal nanoparticles comprise about 0.0001 wt % to about 1.0 wt % of the catalyst and wherein the catalytic metal nanoparticles have a mean particle diameter of about 1 nm to about 4 nm.
