Thermo-responsive functionalized PNIPAM@Ag/Ag3PO4/CN-heterostructure photocatalyst with switchable photocatalytic activity

Photocatalytic Reduction of Aromatic Nitro Compounds with Ag/AgxS Composites under Visible Light Irradiation

“…59 When the cycled Ag/ Ag x S-1 sample was sputtered by Ar + during XPS examination, the mole ratio of S 2− , S 2 2− , S n 2− , and SO 4 2− did not changed obviously, but Ag 0 species presented again (Figure 10c; Table S3, entries 2 and 3). Based on the SPR effect, Ag 0 on the surface of Ag/Ag x S composites was excited to generate the electron and hole (e/h + ) pairs, 60,61 and then the plasmongenerated electrons reduced NB to AN coupling with the protons (H + ) and so Ag 0 is gradually oxidized to Ag + . The atomic ratio of Ag/S increased after reaction as certified by the results of both XPS and ICP, which was ascribed to the transformation of Ag 2 S n to Ag 2 S and Ag 2 SO 4 (Table S3, entries 1 and 2), inducing a loss of S into the solution.…”

Thermally Induced Mechanical Switching of the Second‐Harmonic Generation in pNIPAM Hydrogels‐Linked Resonant Au and Si Nanoparticles

“…[ 56 ] However, above the transition temperature, the conductivity suddenly increased due to the denser arrangement of NPs, enhanced by both the tunnel and contact effects. Such a behaviour created additional transport paths for the charge carriers, [ 57 ] contributing to the E‐FISH effect. To exclude any temperature‐dependent processes affecting the SHG in our materials, we studied the Si NPs and Si/Au NPs without pNIPAM.…”

A smart hydrogel carrier for silver nanoparticles: an improved recyclable catalyst with temperature-tuneable catalytic activity for alcohol and olefin oxidation

“…Moreover, its morphology changes from a shrinking agglomeration to a stretch swelling. 69 The thermo-responsive nature of the catalyst was predicted from the DLS measurements with the LCST value. A few experiments were designed to show different yields below and above the LCST values to confirm the LCST behavior of the catalyst.…”
