摘要: In this study, hierarchically complex hollow cage-like superstructures assembled by ZnO nanorods have been successfully constructed with water-soluble biopolymer sodium carboxymethyl cellulose as crystal growth modifiers. The number of the cage could be adjusted from single-cage, double-cage, multi-cage to connected-cage. A possible formation mechanism has also proposed. catalytic study shows that these good abilities enhance propellant combustion ammonium perchlorate (an important oxidizer used in solid rocket propellants), decreasing its decomposition temperature low 285 °C. Photoluminescence studies reveal increase leads an relative photoluminescence intensity around 500 700 nm, which might attributed radiative defects at interface components structure number.
