Semiconductor oxides are important materials in gas-detection systems
and can be improved by enhancing the sensitivity and selectivity of
oxide sensors to specific gases. This research investigates the effect of
palladium dopant (Pd) on the hydrogen gas-sensing ability of ZnO 2-D
nanostructures. Photolithography was used to pattern electrodes on
various...
Concern about maximizing and improving heterogeneous catalysis has
grown because it is used in a variety of applications. This study focused
on the effect single-walled carbon nanotubes (SWNTs) had on titanium
dioxide (TiO2) catalysis. Two different forms of TiO2, rutile and anatase,
were combined with SWNTs in heterogeneous mixtures and...
