Actinomorphic ZnO/SnO2 core–shell nanorods: Two step synthesis and enhanced etha

Actinomorphic ZnO/SnO2 core–shell nanorods (NRs) were synthesized via a facile two-step synthesis method, in which actinomorphic ZnO NRs (core) with the diameter about 450–1500 nm and the length about 2–7 μm were prepared in advance through a chemical solution method, and then a continuous SnO2 laye
