About: Plasmonic catalysis

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

In chemistry, plasmonic catalysis is a type of catalysis that uses plasmons to increase the rate of a chemical reaction. A plasmonic catalyst is made up of a metal nanoparticle surface (usually gold, silver, or a combination of the two) which generates localized surface plasmon resonances (LSPRs) when excited by light. These plasmon oscillations create an electron-rich region near the surface of the nanoparticle, which can be used to excite the electrons of nearby molecules.

  • In chemistry, plasmonic catalysis is a type of catalysis that uses plasmons to increase the rate of a chemical reaction. A plasmonic catalyst is made up of a metal nanoparticle surface (usually gold, silver, or a combination of the two) which generates localized surface plasmon resonances (LSPRs) when excited by light. These plasmon oscillations create an electron-rich region near the surface of the nanoparticle, which can be used to excite the electrons of nearby molecules. Similar to photocatalysts, plasmonic catalysts can transfer their excitation energy to reactant molecules through resonance energy transfer (RET). Unlike photocatalysts, plasmonic catalysts can also excite reactant molecules by the release of hot carrier electrons which have a high enough energy to completely dissociate from the metal surface. The energy of these hot carrier electrons can be altered by changing the wavelength of light striking the surface and the size of the nanoparticles present, which allows the hot electrons to take on the excitation state needed to catalyze multiple different reactions. Although the field of plasmonic catalysis is still in its infancy, there are clear advantages to utilizing a plasmon-active surface over traditional photocatalysts. Their ability to utilize energy from near-infrared, visible, and ultraviolet light gives plasmon surfaces higher light-capturing efficiency than photocatalysts, which can only utilize ultraviolet light, and the larger possible energy range of the electromagnetic field and emitted electrons make the resulting catalytic effects both broadly applicable and highly tunable.
