Nanochemistry by Thermoplasmonic Effects

Laser Direct Writing of Crystallized TiO2 by Photothermal Effect Induced by Gold Nanoparticles

“…In this case, since the plasmon resonance is involved, this photothermal effect is called thermoplasmonic effect. It has been the subject of intense fundamental and applied research in recent years, with significant advances in the fields of biology, [27][28][29][30] chemistry, [31] catalysis, [32] and physics. [33,34] However, this effect has rarely been used in the field of materials science.…”

Sol–Gel TiO2 Thin Film on Au Nanoparticles for Heterogeneous Plasmonic Photocatalysis

“…8 It is admitted that the interaction of light with MNPs is based on three effects which are the near-field light enhancement, the hot electron transfer, and the generation of heat (called thermoplasmonic effect). 9,10 These three effects can contribute at different levels depending on the nature of the nano-objects, the experimental conditions, and the chemical reactions induced by plasmon excitation. 11−13 The mechanism responsible for photocatalysis has often been attributed to the transfer of hot electrons generated by nonradiative deexcitation.…”

“…Thanks to their localized surface plasmon resonance (LSPR) properties, metal nanoparticles (MNPs) offer particularly interesting properties for applications in photocatalysis, photovoltaics, and more generally for converting light into other energy source. − The use of MNPs allows to convert efficiency of light into other energy such as chemical energy in the form of chemical transformation of basic molecules . It is admitted that the interaction of light with MNPs is based on three effects which are the near-field light enhancement, the hot electron transfer, and the generation of heat (called thermoplasmonic effect). , These three effects can contribute at different levels depending on the nature of the nano-objects, the experimental conditions, and the chemical reactions induced by plasmon excitation. − The mechanism responsible for photocatalysis has often been attributed to the transfer of hot electrons generated by nonradiative deexcitation. , Other works highlight the important role of thermoplasmonic effects. , Finally, under other conditions, the three LSPR effects are considered to explain the reactions involved. , More specifically, experimental and theoretical studies have shown the contribution of hot electron transfer in photocatalysis, such as the production of H 2 , the reduction of CO 2 , , and the decomposition of organic molecules such as the epoxidation of ethylene, the conversion of PNTP into PATP, , or esterification of aldehydes …”

Chemical Method Based on Thermally Activated Free Radical Polymerization to Determine the Temperature in Thermoplasmonics

“…Heating generated by laser-illuminated metal nanoparticles (NPs), known as the thermoplasmonic effect, is finding more and more applications , in both biology and chemistry. , In biology, thermoplasmonics can be used to kill cancer cells − or to observe living organisms requiring high temperatures, known as thermophiles, directly under a microscope. In chemistry, the deliberate and controlled heating of nanoparticles can accelerate chemical reactions or enable the development of lithography techniques …”
