Abstract

original image

Parallelogram-shaped porous ZnO nanosheets with high specific surface area are prepared thorough a precursordirected self-assembly route. The precursor, basic zinc salt, plays dual roles in the assembly that concurrently provides the building blocks and the template. As reported by L. Guo and co-workers on page 48, this porous ZnO structure with active surface defects serves as a highperformance semiconductor substrate for surface-enhanced Raman scattering. This assembly strategy delivers a new idea for designing hierarchical structures and a platform for in-depth investigation of electrochemical properties at the molecule/surface interface.
