Synthesis of novel hybrid mesoporous gold iron oxide nanoconstructs for enhanced catalytic reduction and remediation of toxic organic pollutants

Abstract

Development of highly-efficient, rapid, and recyclable hybrid mesoporous Au–IO NPs nanocatalysts for elimination of toxic environmental contaminants. Thanks to synergistic cooperation of their well-dispersed AuNPs, large surface area/pore volume, and mesoporosity.

“…It is well-known that with the increase of the Au NP shell and particle agglomeration, the SP band shifts to longer wavelengths with higher absorbance intensity. The peak becomes broader and broader due to the coupling of the individual Au NPs when aggregated. , Based on the relative dimensions of the Au shell and the core size, the hybrid MNPs may be designed to scatter and/or absorb light over a broad spectral range including NIR. , While using 690 nm light (common for commercially available diodes) could still excite the NPs, the penetration depth of such light would be significantly reduced, leading to an increased blurring of images if the hybrid MNPs were to be utilized within tissues. Therefore, to provide a more accurate comparison for potential application in biological tissues, estimating the heating responses at 808 nm over other wavelengths within NIR-I based on its reduced scattering seems prudent …”
