Self-assembled 3D architectures of blade-shaped hierarchical hollow microspheres from cristobalite nanosheets with exposed (101) facets

Abstract

3D architectures of ‘blade-shaped’ hierarchical hollow cristobalite microspheres (MSs) assembled from plenty of nanosheets (NSs) with exposed (101) facets were synthesized via a hydrothermal method under catalysis by an organic base. Based on the experimental results, a possible self-assembly mechanism was proposed.
