DOS comparisons of the WO3 before and after NO2 adsorption shows that the most obvious change is that all bands shift towards low energies after adsorption, leading to the partial filling of the conduction band maximum(CBM). DOS analysis suggests...

of aromatic compounds like phenols into their corresponding nitrated compounds using

NaNO2 and wet SiO2 at room temperature with appropriate yields....

was fabricated by deposition of WO3 nanoparticles between electrodes via low frequency AC electrophoretic deposition. Gas sensing measurements showed that this material has a high sensitivity to very low concentrations of NO2 at 250°C and 300°C...

on patterned alumina substrates through low frequency AC electrophoresis

of which, the deposition pattern was studied using optical microscopy and SEM. Exposure of the sensors

to NO2 in the temperature range of 150–300 ◦C resulted in highest...
