A study of low-temperature CO oxidation over mesoporous Cuo-TiO2 nanotube catalysts
( MDPI AG , 2017 , Article)Supported copper oxide nanoparticles have attracted considerable attention as active and non-precious catalysts for many catalytic oxidation reactions. Herein, mesoporous xCuO-TiO2 nanotube catalysts were fabricated, and ... -
Low-Temperature CO Oxidation Over CuO-TiO2 Nanocatalysts
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Among the diverse catalytic processes, the heterogeneous catalytic CO oxidation is an important reaction for removal of small amounts of poisoning CO in fuel cell applications and environmental remediation. Therefore, there ... -
On the nature of defect states in tungstate nanoflake arrays as promising photoanodes in solar fuel cells
( Royal Society of Chemistry , 2016 , Article)An electrochemical method is presented to study the nature of the defect states in sub-stoichiometric tungsten oxide nanoflake photoanodes used in water splitting. First, stoichiometric/sub-stoichiometric tungstate nanoflake ... -
Optimization Of The Electronic And Optical Properties Of Tio2 For Clean Fuel Production
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)Among different crystal structures and morphologies of TiO2, vertically oriented anatase nanotube arrays show the highest activity for solar energy conversion. However, the long-standing bottleneck is the fact that TiO2 ... -
Self-assembled zirconia nanotube arrays: Fabrication mechanism, energy consideration and optical activity
( Royal Society of Chemistry , 2014 , Article)We present a comprehensive roadmap for the precise control of the dimensions and optical properties of anodically fabricated zirconia nanotubes. The effects of anodization time, applied voltage, solvent composition, as ... -
Silver Nanoparticles-Decorated Titanium Oxynitride Nanotube Arrays for Enhanced Solar Fuel Generation
( Nature Publishing Group , 2017 , Article)We demonstrate, for the first time, the synthesis of highly ordered titanium oxynitride nanotube arrays sensitized with Ag nanoparticles (Ag/TiON) as an attractive class of materials for visible-light-driven water splitting. ... -
TiO2 nanotubes with ultrathin walls for enhanced water splitting
( Royal Society of Chemistry , 2015 , Article)We demonstrate, for the first time, the synthesis of titania nanotubes with ultrathin (3–5 nm) wall thickness. As revealed by the incident photon-to-current collection efficiency (IPCE) and electrochemical impedance ...
