Can we harness the power of nanosheets to purify our air? This study explores a promising approach to photocatalytic nitric oxide (NO) removal using plasmonic Bi-modified Bi2Sn2O7 nanosheets. The research aims to enhance the photocatalytic activity of Bi2Sn2O7, a potential photocatalyst with limitations due to rapid recombination of photo-generated carriers. By preparing Bi/Bi2Sn2O7 through in situ deposition of Bi, the authors demonstrate improved photoabsorption and photocatalytic performance. The photocatalytic NO removal rate increased significantly compared to pure Bi2Sn2O7. The enhanced performance is attributed to the surface plasmon resonance (SPR) effect of Bi nanoparticles, which promotes charge separation and enhances the generation of reactive radicals. This research highlights the potential of Bi/Bi2Sn2O7 composite photocatalysts for air purification systems. The material exhibits excellent photocatalytic stability, making it a promising candidate for practical applications in reducing harmful gaseous pollutants.
