Self‐assembly of ZnO porous nanosheets with novel parallelogram morphology and high specific surface area is achieved by a one‐pot alkalization reaction. The growth mechanism relies on the dual roles of the precursor: providing the building blocks and the assembling template concurrently. This porous structure with active surface defects serves as a high‐performance semiconductor substrate for surface‐enhanced Raman scattering (SERS).
