1. A composition comprising solid particles of an oxide of an element selected from the group consisting of Si, Ti, Fe, Zn and Al and at least one solid carrier, wherein the solid particles each have a surface functionalized with at least one terminal cyclocarbonate group attached to the surface via a linker, wherein the at least one terminal cyclocarbonate group and the linker has the structure set forth in formula (I):
![]() wherein:
n=1 or 2;
[X] is an element selected from the group consisting of O, N and C;
[Y] represents an alkylene group carrying 1-20 C atoms, that can be linear, branched, or cyclic, or connected to a carbonyl or an ether group;
q=0 or 1; and
R1 is a coupling reactive group serving as a linker selected from silanes, siloxanes, phosphates or carboxylates,
wherein the composition comprising the solid particles in an amount comprised between 0.1% and 50% by weight, relative to the total weight of the composition, wherein the solid carrier is an absorbent material obtained from a processed corncob.
