Formaldehyde, a harmful indoor air pollutant with carcinogenic and irritative effects, poses significant health risks and economic burdens. However, formaldehyde is commonly utilized as an adhesive in wood and wood composites, with aldehyde-based resins frequently found in paints, flooring, and furniture. In our research, we propose a highly efficient method for formaldehyde removal using a plasmonic nanoheater. Gold nanorod (GNR) heaters embedded in paints accelerate formaldehyde removal via plasmonic heating. Under light illumination, these GNRs increase the surface temperature to 60 °C, enhancing formaldehyde release 4 times faster in the paint. With its high efficiency, our approach holds promise for applications in indoor air purification, environmental remediation, and industrial emissions control, contributing to healthier and safer indoor environments.

Abstract
Formaldehyde, a harmful indoor air pollutant with carcinogenic and irritative effects, poses significant health risks and economic burdens. However, formaldehyde is commonly utilized as an adhesive in wood and wood composites, with aldehyde-based resins frequently found in paints, flooring, and furniture. In our research, we propose a highly efficient method for formaldehyde removal using a plasmonic nanoheater. Gold nanorod (GNR) heaters embedded in paints accelerate formaldehyde removal via plasmonic heating. Under light illumination, these GNRs increase the surface temperature to 60 °C, enhancing formaldehyde release 4 times faster in the paint. With its high efficiency, our approach holds promise for applications in indoor air purification, environmental remediation, and industrial emissions control, contributing to healthier and safer indoor environments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
