Abstract
A secondary growth procedure described herein is used to prepare finned zeolites. The finned zeolites possess properties that are distinctly unique compared to crystals of similar size lacking fins. The procedure is amenable to a wide range of zeolite crystal structures.
Claims4
1-17. canceled
Finned zeolite crystals, comprising:
- a zeolite seed crystal portion, wherein the seed portion comprises a single crystallographic registry, and wherein the seed portion comprises a network of pores;
- and
- a plurality of epitaxially grown fins extending from outer surfaces of the zeolite seed crystal portion, wherein the epitaxially grown fins comprise a single crystallographic registry that is identical to the single crystallographic registry of the zeolite seed crystal portion, wherein the epitaxially grown fins comprise a network of pores that is continuous with the network of pores of the zeolite seed crystal portion, wherein the zeolite seed crystal portion has a characteristic size of β, wherein the epitaxially grown fins have a characteristic size of α, wherein β is greater than α, and wherein a is less than 50 nm.
