“…PL technology was used to study the migration process of photogenerated carriers in the as-acquired samples. 59 As shown in Fig. 6a, due to the rapid recombination of the photoproduced carrier generated by the CP sample, the uorescence emission spectrum of the CP sample has a maximum emission peak at 658 nm, which has a strong wide range (638-740 nm).…”

“…Similar phenomena have been recognized as a Cu@Co core-shell nanostructure. 33 In conclusion, the relative position of the Cu PNAs in the TiO 2 substrate is the key factor to determine the stable LSPR effect. The case of Cu PNAs embedded at a certain depth in the TiO 2 substrate represented by Model D has the optimal LSPR effect, which can play an important role in PEC water splitting devices.…”

“…[103] Considering the inherent properties of Cu, core-shell Cu@Co bimetal was prepared that exhibited high CO 2 adsorption and activation, attributed to the fast migration of charge carriers from the incorporated Co layer. [104] This resulted in a remarkably enhanced rate of CO generation of 920.28 µmol h -1 g -1 and high CO selectivity up to 98%, whereas pure Cu could achieve CO selectivity only up to 78% (Figure 10c,d). [104] An essential aspect of these bimetallic plasmonic photocatalysts is to hone the loading of the non-plasmonic metal.…”

Meanwhile, global energy demands also continue to rise. In such a situation, inspiration from nature's process of photosynthesis can be taken to target both the challenges, and artificial systems can be employed that recycle atmospheric CO 2 into valuable hydrocarbon fuels. [2,3] At the outset, artificial photosynthesis seems a straightforward and sustainable approach. However, conversion of CO 2 into value-added chemicals such as, carbon monoxide (CO), formic acid (HCOOH), methanol (CH 3 OH), methane (CH 4 ), and other C 2+ products is an endergonic process, involving a significant positive change in Gibbs free energy. [4] Also, kinetics and product selectivity are major challenges to tackle. While the energy barriers might be surpassed by thermal or electrical energy input to catalysts, economic feasibility, product yields, and selectivity are complex factors. A better strategy is to utilize solar energy to drive the thermodynamically uphill reactions and produce chemical fuels in a renewable and sustainable way. Moreover, the light excitation of catalysts allows more controlled CO 2 reduction. Nanotechnology in this scenario provides myriad opportunities to develop photocatalysts that produce electron-hole pairs upon light illumination and carry out the required chemical transformation. Semiconductor materials, mainly titania (TiO 2 ), have dominated the photocatalysis field but pose constraints regarding limited visible light absorption (while visible light constitutes ≈46% of the sunlight) and other factors. [5][6][7][8] As such, the quest to develop an efficient alternative has recently led to the emergence of photocatalysts consisting of plasmonic metal nanoparticles, mainly Au, Ag, Cu, and Al, that can harvest visible light with high optical cross-section and serve as a platform for surface catalyzed reactions. [9][10][11][12][13] Plasmonic nanostructures exhibit strong interaction with the incident electromagnetic radiation and trigger localized surface plasmon resonance (LSPR), leading to enhancement of local electric fields and subsequent generation of energetic charge carriers and heat that can be exploited in tremendous applications of chemical transformation. [14] The energetic charge carriers are generated with a non-equilibrium distribution, and their potential energy depends upon the electronic band structure of the nanomaterial. This regulates their overall contribution to the chemical reaction's free energy and the extent of activation of the reactants. Recent theoretical and experimentalThe realization of the strong interaction of plasmonic nanostructures with electromagnetic radiation, subdiffraction-limit field localization, and unusually high field enhancement enables immense opportunities to harness visible light in the field of photocatalysis. Plasmon-induced energetic charge carriers allow the metal nanostructures to catalyze surface reactions with selective pathways that are rather a holy grail of thermal catalysis. An intriguing application of plasmonic photocatalysis includes sequestr...
