Facile synthesis of Ag nanoparticles supported on TiO2 inverse opal with enhanced visible-light photocatalytic activity

Template free fabrication of porous g-C3N4/graphene hybrid with enhanced photocatalytic capability under visible light

“…This probably is attributed to the porous structure formed in samples treated at the high temperatures, which improve the optical absorption of materials. 22 Most remarkably, the absorption tail disappeared for porous g-C 3 N 4 /grapheme. Instead, featureless absorption between 450 and 800 nm is exhibited in Fig.…”

Pore confinement effects and stabilization of carbon nitride oligomers in macroporous silica for photocatalytic hydrogen production

“…observed. [61,70,73] DRUV spectra for 5 -7 (Fig. 4) shows that CN addition does not significantly change the stop band positions at 380 and 610 nm, however their intensity is significantly reduced for 6 and 7, indicating that CN species are formed inside the macropores during cyanamide pyrolysis and do not conformally coat the surface of macSiO2.…”

Silver nanoparticles deposited inverse opal film as a highly active and uniform SERS substrate

“…These substrates provide an amazingly high enhancement factor and reproducibility of the SERS signals. Among these nanostructures, three-dimensionally (3D) ordered porous structure has advantages of large surface area available for the formation of the so-called "hot spots" and the adsorption of target analytes [13][14][15][16].…”
