Plasmon resonances for solar energy harvesting: A mechanistic outlook

Plasmon Modes Induced by Anisotropic Gap Opening in Au@Cu2O Nanorods

“…The mechanisms involved in the plasmonic enhancement of the photocatalytic activities of semiconductors have been discussed extensively in a number of studies. [ 2,3,[21][22][23] Two major mechanisms have been generally identifi ed. One is plasmonenhanced light absorption, and the other is plasmonic sensitization, where plasmon-excitation-induced hot electrons are injected into the conduction band of the semiconductor.…”

“…As a result, the integration of plasmonic metals with semiconductors can improve the photocatalytic efficiencies of semiconductors owing to the unique and attractive plasmonic properties of metal nanocrystals. The mechanisms involved in the plasmonic enhancement of the photocatalytic activities of semiconductors have been discussed extensively in a number of studies . Two major mechanisms have been generally identified.…”

Eco-Friendly Physical Activation Methods for Suzuki–Miyaura Reactions

“…A supposable mechanism has been proposed to explain the tentative reaction pathway that may occur under visible light irradiation. The resonant excitation of plasmonic nanoparticles, which is accomplished by matching frequencies with those of the incident electromagnetic radiation, undergoes relaxation within tens of femtoseconds [168][169][170]. Relaxation can occur via either radiative or non-radiative emission.…”

Controlled Assembly of a Ternary‐Component Photocatalyst: Illustrating the Importance of Interfacial‐Integration of Ag‐ZnO‐rGO in Visible‐Light‐Induced Catalytic Activity

“…Currently the focus has been to design multi‐component materials with integrated desirable properties to address the shortcomings of the existing photocatalysts . Particularly, the usage of noble metals like Ag, Au, Pt as co‐catalysts for semiconductor‐based photocatalysts has shown promise for extending the light absorption towards visible‐light and enhanced interaction with the electromagnetic radiation via the surface plasmon resonance phenomenon . Moreover, the interaction of the metal nanoparticles with semiconductors is also vital in order to deter the recombination of the photo‐excited species (electron and hole) via the Schottky barrier created at the metal‐semiconductor interface and thereby increases the catalytic activity …”

“…[4][5][6][7] Particularly, the usage of noble metals like Ag, Au, Pt as co-catalysts for semiconductor-based photocatalysts has shown promise for extending the light absorption towards visible-light and enhanced interaction with the electromagnetic radiation via the surface plasmon resonance phenomenon. [8][9][10][11][12] Moreover, the interaction of the metal nanoparticles with semiconductors is also vital in order to deter the recombination of the photo-excited species (electron and hole) via the Schottky barrier created at the metal-semiconductor interface and thereby increases the catalytic activity. [13][14][15][16][17][18] Amongst various materials, Ag-ZnO hetero-system has been extensively studied because of its suitability to have efficient electron transfer from metal to the semiconductor.…”
