Titanium dioxide nanotube structure is chosen as an active component in the gas sensor because of its highly sensitive electrical resistance to hydrogen over a wide range of concentrations. The objective of the work is to fabricate good quality titania nanotubes suitable for hydrogen sensing applications. The fabrication method used is anodizing method. The anodizing parameters namely the voltage, time duration, concentration of hydrofluoric acid in water, separation between the electrodes and the ambient temperature are varied accordingly to find the optimum anodizing conditions for production of good quality titania nanotubes. The highly ordered porous titania nanotubes produced by this method are in tabular shape and have good uniformity and alignment over large areas. From the investigation done, certain set of anodizing parameters have been found to produce good quality titania nanotubes with diameter ranges from 47 nm to 94 nm. © 2010 American Institute of Physics. date: 2010 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-77953084964&doi=10.1063%2f1.3377799&partnerID=40&md5=a9714320259b48d7bb1b85b020c89975 id_number: 10.1063/1.3377799 full_text_status: none publication: AIP Conference Proceedings volume: 1217 place_of_pub: Langkawi, Kedah pagerange: 134-139 refereed: TRUE isbn: 9780735407602 issn: 0094243X citation: Dzilal, A.A. and Muti, M.N. and John, O.D.
