Development Of Sno2-Based Thick-Film Gas Sensor Using Screen-Printing Technique For Detection Of Ethanol Gas
Mesoporous SnO2 were synthesized via soft-template method by using cationic surfactant (cetyltrimethylammonium bromide: CTAB) as template and hydrated tin chloride (SnCl4.5H2O) as inorganic precursor to be used as gas sensing materials. The performance of selected thick-film sensor under various ope...
