Growth Of Zno Nanorods On Wire Via Sonochemistry Method For Glucose Sensing.
Masters thesis, Perpustakaan Hamzah Sendut.
Abstract
There has been much research on growth of ZnO nanorods on vanous
substrates, and various growth methods. Sonochemical method is a well-known
method for growing nanorods. Metal wire is a suitable substrate for the growth of
ZnO nanorods as it can then be used as sensor electrode for sensing application.
However there has not been any report on growth of ZnO nanorods on metal wire
directly using sonochemical method. ZnO nanorods were directly grown on four
different wires (silver (Ag), nickel (Ni), copper (Cu), and tungsten (W)) through
sonochemical method and the best sample was chosen as electrode and tested for
glucose sensing. Zinc nitrate hexahydrate and hexamethylenetetramine (HMT) were
used as precursors for the growth of ZnO nanorods. The optimum condition for the
growth of ZnO nanorods were determined by varying precursor molarity, sonication
time and molar ratio of precursor solution.
