“…61 The control of the surface temperature is nevertheless a point of intense debate for plasmonic photo catalysts. 22,62 In any case, Figure 5A displays the rate (normalized by a constant considering the amount of Pt of the catalyst) behavior under thermo-photo and dark conditions. Under the relatively well controlled temperature conditions of the experiment, the mentioned study also illustrates (Figure 5B) that the excess reaction rate (here defined as "hot electron" -Hot e, measured at two different temperatures called IT and a higher one, FT) has a power-like dependence on light intensity, a feature compatible, according to the authors, to an electrondriven chemical reactions, directly reflecting the critical contribution of the hot electrons created after illumination of the composite (plasmonic) solid.…”

“…One of the most studied plasmon-driven photocatalytic reactions is the reduction and dimerization of 4-nitrobenzenethiol (4-NBT) SAM, which can additionally be used as a molecular Raman probe and photocatalytic activity indicator. The photocatalytic reduction of 4-NBT to 4,4 -dimercaptoazobenzene (DMAB) is a complex reaction previously reviewed in the literature [33,34]. Driven by laser irradiation, the reaction depends on several parameters, including laser wavelength, exposure time, laser power, and environmental conditions such as pH.…”

Structural electronics, as well as flexible and wearable devices are applications that are possible by merging polymers with metal nanoparticles. However, using conventional technologies, it is challenging to fabricate plasmonic structures that remain flexible. We developed three-dimensional (3D) plasmonic nanostructures/polymer sensors via single-step laser processing and further functionalization with 4-nitrobenzenethiol (4-NBT) as a molecular probe. These sensors allow ultrasensitive detection with surface-enhanced Raman spectroscopy (SERS). We tracked the 4-NBT plasmonic enhancement and changes in its vibrational spectrum under the chemical environment perturbations. As a model system, we investigated the sensor’s performance when exposed to prostate cancer cells’ media over 7 days showing the possibility of identifying the cell death reflected in the environment through the effects on the 4-NBT probe. Thus, the fabricated sensor could have an impact on the monitoring of the cancer treatment process. Moreover, the laser-driven nanoparticles/polymer intermixing resulted in a free-form electrically conductive composite that withstands over 1000 bending cycles without losing electrical properties. Our results bridge the gap between plasmonic sensing with SERS and flexible electronics in a scalable, energy-efficient, inexpensive, and environmentally friendly way.

“…[4] Recently, these plasmonic metal nanostructures are being studied in combination with other active metal species, for example, Pd, Ru, Ni, and Pt in order to improve their catalytic and optical properties. [5] In the last decade, plasmon-mediated heterogeneous catalysis was explored in several important catalytic reactions to improve the product yield under mild reaction conditions such as hydrogen generation, [6][7][8][9] CO 2 reduction, [10,11] water purification [12] and carbon-carbon coupling reaction. [13][14][15][16] The immobilization of these novel plasmonic nanostructures has been reported on a variety of support materials ranging from insulator mesoporous-macroporous silica to semiconducting TiO 2 and metal-organic frameworks (MOFs).…”

The formation of hybrid plasmonic nanocatalysts made of Au nanoparticles (NPs) combined with catalytically active NPs has gained great attention owing to their interesting properties and efficient catalysis under visible light irradiation. However, the research on the combination of plasmonic metal NPs with unique support frameworks is still limited. In this report, the varying ratio of AuxPdy prepared by the extrusion method on the CuClP framework has been correlated to its optimized catalysis in the Suzuki‐Miyaura coupling reaction in dark and under visible light irradiation. The prepared catalysts AuxPdy/CuClP were characterized by spectroscopic techniques to understand the structural and electronic modification with different metal ratios. The presence of bimetallic NPs on the surface was confirmed by HR‐TEM measurements and [MCl4]n− species in the framework were validated by XPS, FT‐EXAFS, DR UV‐Vis‐NIR, and Raman analysis. The obtained results display the superior catalytic performance and highest plasmonic enhancement factor over Au1Pd1/CuClP under visible light irradiation, which was facilely recycled and reused for several cycles. The hot‐electron transfer mechanism has been discussed for enhanced catalysis in the plasmon‐driven Suzuki−Miyaura coupling reaction. These results are highly significant in the rational design of new plasmonic photocatalysts combined with unique support materials.
