Plasmonic Materials: Opportunities and Challenges on Reticular Chemistry for Photocatalytic Applications

Abstract

Solar‐light harvesting materials currently represent a hot topic in catalysis due to the several applications where they can be used. Among the recent strategies to enhance the photocatalytic performance of semiconductor materials, plasmonic metals are trending. Coupling plasmonic metal nanoparticles with a semiconductor material can give unique synergistic effects and properties. Especially when reticular materials, like metal organic frameworks, are used to generate these plasmonic nanocomposites. Herein, a brief introduction to the localized surface plasmon resonance and reticular materials design and fabrication is given. Also, the advantages of plasmonic with reticular nanostructures are discussed. The following highlights summarize recent advances in sunlight‐driven plasmonic reactions (CO2 photoreduction, water depollution, gas sensing, and optical reactions). Theoretical and experimental approaches are discussed, regarding mechanistic phenomena of nanocomposites with reticular materials and surface plasmon metals. A proper discussion and perspective of the remaining challenges and future opportunities for plasmonic metals with reticular materials in the field of photocatalysis is given in the overview and conclusion.

In‐situ Integrated Plasmonic TiN@ZIF‐67 Composites for the Photoreduction of CO2into Solar Fuels: Insights into their Plasmonic Interaction and Mechanism

“…It could be seen that all samples exhibited a characteristic type-I hysteresis. [35] The BET surface area of bare-ZIF-67 (line a) was estimated to be ~1605 m 2 g À 1 , which agrees with our previous reports, [6,36] but it is found to be decreased for both the composites, which may be due to the integration of TiN onto the ZIF-67. However, the directlyintegrated ZIF67/TiN composite (TiN/PVP-ZIF (line b)) showed an increased surface area of ~1548 m 2 g À 1 as compared to the in-situ integrated composite (TiN/ImCHO-ZIF (line c)) that showed ~1256 m 2 g À 1 .…”

Pharmaceuticals in the Aquatic Environment: A Review on Eco-Toxicology and the Remediation Potential of Algae

“…and high treatment costs [145]. Due to this limitation, more sophisticated methods are currently proposed, including the development of a variety of plasmonic materials to harvest light more efficiently for AOPs [146]. The possibility of pharmaceutical removal using plasmonic materials is not yet fully explored; however, the degradation of some drugs, including ibuprofen and levofloxacin, has been reported [146].…”

Au Nanoparticle-Anchored Hollow Nanospheres of a Single-Atomized Porphyrin-Covalent Organic Framework Hybrid for Boosting Photoreduction of CO2 under Solar Irradiation

“…When light is shone on a sample of Au nanoparticles, the electrons within them are free to conduct the electricity, creating a resonance with the incident light’s electromagnetic field. Thus, the hot electrons with surplus energy that are triggered by LSPR can either go to the adjacent absorbent or return to the ground state by dissipating the energy to the environment. − When these factors are taken into account, it becomes effective to construct COF photocatalyst systems that integrate plasmonic Au nanoparticles toward CO 2 reduction.…”
