The role of the gold–platinum interface in AuPt/TiO₂-catalyzed plasmon-induced reduction of CO₂ with water

Abstract

Bimetallic gold-platinum nanoparticles have been widely studied in the field of nanoalloys, catalysis and plasmonics. Many preparation methods can lead to the formation of these bimetallic nanoparticles (NPs). The structure...

KPFM visualisation of the Schottky barrier at the interface between gold nanoparticles and silicon

“…8,21 Moreover, knowing the value of the SBH and the band bending area is of great interest for understanding how hot carriers can be generated using the plasmonic properties of AuNPs on doped silicon substrates. 13,15,22,23…”

“…2,12 It has recently been applied for AuNPs on TiO 2 by several groups. [9][10][11][13][14][15] In the present study, we used KPFM for analysing the geometry of the Schottky barrier formed by 55 nm AuNPs grafted on silicon with either n-or p-doping. This is a model system that sheds light on the mechanism of Schottky barrier formation for nanostructures.…”

FERRITIN nanocages used as programmable bricks for biomolecular electronics

“…[149,158] It has recently been applied for AuNPs on TiO2 by several groups. [18,156,157,[159][160][161] In this thesis, we used KPFM for analysing the profile of electric potential of the Schottky barrier formed by 50 nm AuNPs grafted on silicon with either n-or p-doping.…”

“…[155,166] Moreover, knowing the value of the SBH and the band bending area is of great interest for understanding how hot carriers can be generated using the plasmonic properties of AuNPs on doped silicon substrates. [152,159,160,167] This study performed during the first year of the thesis allowed us to become familiar with the parameters of the KPFM and the electronic phenomena (interaction of metal/semiconductor) that influence the measure of the CPD. Therefore, this work is a lead-in for the study of the electrostatic behaviour of ferritin nanocages immobilized on silicon.…”
