Synergistic modification of TiO 2 with Fe 2 O 3 , Fe 3 O 4 , and CaO to boost photocatalytic NO x oxidation, selectivity, and storage efficiency under UV light
The research aims to improve the oxidation and storage of NOx gases using modified photocatalysts.
Utilized P25/Fe2O3/CaO and P25/Fe3O4/CaO as photocatalysts.
Evaluated the oxidation and storage efficiency of NOx gases.
Conducted experiments under UV light to assess performance.
Enhanced photocatalytic activity was observed for the modified catalysts.
Improved selectivity for NOx oxidation was achieved.
Increased storage efficiency for NOx gases was noted.
Abstract
This study explores the oxidation and storage of NO x gases ( i.e. , NO 2 and NO) on the surfaces of P25/Fe 2 O 3 /CaO and P25/Fe 3 O 4 /CaO photocatalysts.
