摘要： A composition comprising: a bulk material; and at least one surface; the bulk material comprising ions of a metal M bonded to one another via linker groups; the surface comprising ions of a metal M' bonded to one another via linker groups; the metals M and M' being the same or different; the surface comprising at least one first site A and at least one second, different site B; the site A having a hydroxyl group bonded thereto, said site A optionally being capable of interacting with C02; the site B being a Lewis acidic site capable of binding a C02 molecule; is described. Methods of forming the composition and the use of the composition as a catalyst, in particular to catalyse reactions in which C02 is incorporated into the structure of a molecule, in particular a polymer, are also described.
