Abstract

THE PRESENT INVENTION PROVIDES AN INCORPORATED BORON-DOPED GOLD FUNCTIONALIZED METALLIC CARBON NANOTUBE [20] STRUCTURE FOR HYDROGEN SULPHIDE GAS SENSOR DEVICE. THIS TYPE OF CHEMICAL RESISTIVE SENSOR CAN DETECT HYDROGEN SULPHIDE GAS MOLECULES [28] AT THE SUB PPM LEVEL. THE UNIQUE FEATURE OF THE SENSOR IS THE GOLD FUNCTIONALISED BORON DOPED CARBON NANOTUBES [20] STRUCTURE WHICH IS USED TO ENHANCE THE SELECTIVITY AND SENSITIVITY TOWARDS HYDROGEN SULPHIDE GAS. WHEN HYDROGEN SULPHIDE GAS MOLECULES [28] ARE ABSORBED ON THE GOLD FUNCTIONALISED BORON DOPED CARBON NANOTUBES [20] SURFACE A CHANGE IN THE RESISTIVITY OF THE SENSOR IS CAUSED, THEREFORE ALLOWING DETECTION.
