Platinium－Gallium oxide nanowires, a preparation method thereof, and gas sensor using the same

摘要

PURPOSE: A platinum-gallium oxide nanowire, a manufacturing method thereof, and a gas sensor using the same are provided to have improved sensing sensitivity and a response rate, thereby being utilized for sensing a gas leakage, measuring the concentration of gas, and recording and alarming. CONSTITUTION: A method for manufacturing a platinum-gallium oxide nanowire includes the following steps of: manufacturing a gallium oxide nanowire by using gallium nitride powder; coating a platinum thin film on the manufactured gallium oxide nanowire; and heat-treating the gallium oxide nanowire on which the platinum thin film is coated. The platinum-gallium oxide nanowire based on one-dimension nanostructure has large surface area. The diameter of the gallium oxide nanowire is 80 nm-120 nm.
