Abstract
Official abstract text for this publication.
Provided herein are compositions and methods for use of an organosilica material comprising a copolymer of at least one monomer of Formula [R 1 R 2 SiCH 2 ] 3 (I), wherein, R 1 represents a C 1 -C 4 alkoxy group; and R 2 is a C 1 -C 4 alkoxy group or a C 1 -C 4 alkyl group; and at least one other monomer of Formula [(Z 1 O) x Z 2 3-x Si—Z 3 —SZ 4 ] (II), wherein, Z 1 represents a hydrolysable functional group; Z 2 represents a C 1 -C 10 alkyl or aryl group; Z 3 represents a C 2 -C 11 cyclic or linear hydrocarbon; Z 4 is either H or O 3 H; and x represents any one of integers 1, 2, and 3. The composition may be used as a support material to covalently attach transition metal cations, as a sorbent for olefin/paraffin separations, as a catalyst support for hydrogenation reactions, as a precursor for highly dispersed metal nanoparticles, or as a polar sorbent for crude feeds.
