1. A composition of matter comprising (a) a solid material having pores, and (b) a gel; wherein the gel is substantially localized within the pores of the solid material; and wherein the gel comprises at least one catalytically active element, and optionally comprises chromium when the catalytically active element is other than chromium. 2. The composition of claim 1 wherein the solid material having pores is selected from the group consisting of alumina, silica, titania, zirconia, carbon, molecular sieves, porous minerals, microporous, mesoporous and macroporous materials, montmorillonites, aluminosilicate clays, and binary, ternary, quaternary and higher order oxides, carbides, nitrides, phosphates, and sulfides. 3. The composition of claim 2 wherein said catalytically active metal is selected from the group consisting of platinum and gold. 4. The composition of claim 1 wherein said catalytically active element is chromium and said solid material having pores is alumina. 5. A gel composition comprising a gel that is substantially localized within the pores of a solid material selected from the group consisting of alumina, silica, titania, zirconia, carbon, molecular sieves, porous minerals, montmorillonite clay, alumninosilicate clays, carbides, nitrides, phosphates, and sulfides. 6. A process for preparing a composition of matter comprising (a) a solid material having pores, and (b) a gel; wherein the gel is substantially contained within the pores of the solid material; wherein the gel comprises at least one catalytically active element, and optionally comprises chromium when the catalytically active element is other than chromium; wherein the process comprises contacting a solid material having pores with, in any order, a protic solution and a non-aqueous solution; wherein the solution added first is at incipient wetness; wherein one of either the protic solution or the non-aqueous solution comprises at least one soluble compound comprising an inorganic element selected from the group consisting of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Y, La, Ti, Zr Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Ru, Os, Co, Rh Ir, Ni, Pd Pt, Cu, Ag, Au, Zn, Cd, B, Al, In, Si, Ge, Sn, Pb, P, As, Sb, Bi, S, Se Te, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu and lanthanides of the Periodic Table; wherein the non-aqueous solution comprises a gel-forming precursor; and wherein gel formation occurs substantially within the pores of the solid material. 7. The process of claim 6 wherein the solid material laving pores is a catalyst support selected from the group consisting of alumina, silica, titania, zirconia, carbon, molecular sieve, porous mineral, montmorillonite clay, aluminosilicate clay, carbide, nitride, phosphate, and sulfide; and said gel-forming precursor comprises at least one soluble compound comprising an inorganic element selected from the group consisting of aluminum, silicon, titanium, zirconium, niobium, tantalum, vanadium, molybdenum and chromium. 8. The process of claim 7 wherein the catalyst support is alumina, and the gel-forming precursor is a chromium salt.
