“…A first relevant example is the report by Baker and coworkers, [128] where the fate and role of dodecanethiol (DDT) at the surface of Au NPs (≈2 nm) for CO 2 RR is studied in comparison with bare and PPh 3 -caped Au NPs and DDT-capped flat Au surfaces (Table 3, entries [48][49][50][51]. During the first minutes under negative potential, DDT partially desorbs from the Au NPs surface but remains at lower surface coverage at longer times.…”

Analogously to enzymatic catalysis, where the active metal sites and their environment are controlled by protein residues, the catalytic properties of metal nanoparticles (NPs) can be tuned by carefully selecting their surface-coordinated species. In artificial photosynthesis, surface-functionalization emerged in the last decade, grounded on the development of reliable methods for tailored synthesis, advanced characterization and theoretical modeling of metal NPs, altogether with the aim of transferring to the nanoscale the mechanistic knowledge acquired from molecular complexes. Metal NPs surface-functionalization modulates the energetics of key catalytic intermediates, introduces second coordination sphere effects, influences the catalyst-electrolyte interface, and determines the metal NPs surface coverage and, accordingly, the number of accessible active sites. In photoactivated systems, metal NPs surface-functionalization may play a key role in modulating the charge transfers and recombination processes between the light absorber and the active sites and in the light absorber itself. Thus, after a presentation of the most relevant synthetic methods to produce well-defined surface-functionalized metal NPs, a critical analysis of why the above effects are the cornerstone in enhancing their catalytic performance in the key processes of artificial photosynthesis, namely the oxygen evolution reaction, the hydrogen evolution reaction, and the CO 2 reduction reaction, is given.

“…In the past two decades, carbon allotropes made of hexagonal arrangements of sp 2 -bonded carbon atoms have led the branch of Nanotechnology. [84][85][86][87][88][89] After the discovery of fullerene [90] (0D) and carbon nanotubes [91] (1D), the field of 2D materials had a turning point in 2004 after the isolation of graphene from graphite, which was first reported by Novoselov et al [23] 2D materials benefit from their thin layered skeleton that provides them with outstanding physicochemical properties different from those of their bulk counterparts. For example, graphene, the most studied 2D material, exhibits excellent electrical, thermal, optical, and mechanical features, amongst other, making it attractive for being used in a vast number of applications.…”

The ability of electronic devices to act as switches makes digital information processing possible. Succeeding graphene, emerging Inorganic 2D Materials (i2DMs) have been identified as alternative 2D Materials to harbor a variety of active molecular components to move the current silicon‐based semiconductor technology forward to a post‐Moore era based on molecule‐based information processing components. In this regard, i2DMs benefits not only for their prominent physiochemical properties (e.g., the existence of band gap, contrary to graphene), but also their high surface‐to‐volume ratio rich in reactive sites (functionalization capability). Nonetheless, since this field is still in an early stage, having knowledge of both i) the different strategies for molecularly functionalizing the current library of i2DMs, and ii) the different types of active molecular components is a sine qua non condition for a rational design of stimuli‐responsive i2DMs capable of performing logical binary operations at the molecular level. Consequently, this Review provides a comprehensive tutorial for covalently anchoring ad hoc molecular components —as active units triggered by different external inputs— onto pivotal i2DMs to assess their role in the expanding field of Molecule‐Programmable Nanoelectronics for electrically monitoring bistable molecular switches. Limitations, challenges, and future perspectives of this emerging field which crosses materials chemistry with computation are critically discussed.This article is protected by copyright.

“…Noble metal nanoparticles (NPs), such as Au NPs [9,10], Pt NPs [11,12], Ru NPs [13,14], Ag NPs [15,16], and so on, have been used as co-catalysts to work with photocatalysts for enhanced photocatalytic performance, not only because they play the crucial roles of being photoinduced electron trappers due to their superior electron conductivities, but also because of the surface plasmon resonance (SPR) effect caused by the mutual oscillation between incident light and the electrons on the surface of noble metal NPs. Ag nanoparticles are a good choice for constructing noble metal NPs/semiconductor heterostructures, due to their facile preparation and relatively low cost.…”

In this study, n-p Bi2O2CO3/α-Bi2O3 heterojunction microtubes were prepared via a one-step solvothermal route in an H2O-ethylenediamine mixed solvent for the first time. Then, Ag nanoparticles were loaded onto the microtubes using a photo-deposition process. It was found that a Bi2O2CO3/α-Bi2O3 heterostructure was formed as a result of the in situ carbonatization of α-Bi2O3microtubes on the surface. The photocatalytic activities of α-Bi2O3 microtubes, Bi2O2CO3/α-Bi2O3 microtubes, and Ag nanoparticle-loaded Bi2O2CO3/α-Bi2O3 microtubes were evaluated based on their degradation of methyl orange under visible-light irradiation (λ > 420 nm). The results indicated that Bi2O2CO3/α-Bi2O3 with a Bi2O2CO3 mass fraction of 6.1% exhibited higher photocatalytic activity than α-Bi2O3. Loading the microtubes with Ag nanoparticles significantly improved the photocatalytic activity of Bi2O2CO3/α-Bi2O3. This should be ascribed to the internal static electric field built at the heterojunction interface of Bi2O2CO3 and α-Bi2O3 resulting in superior electron conductivity due to the Ag nanoparticles; additionally, the heterojunction at the interfaces between two semiconductors and Ag nanoparticles and the local electromagnetic field induced by the surface plasmon resonance effect of Ag nanoparticles effectively facilitate the photoinduced charge carrier transfer and separation of α-Bi2O3. Furthermore, loading of Ag nanoparticles leads to the formation of new reactive sites, and a new reactive species ·O2− for photocatalysis, compared with Bi2O2CO3/α-Bi2O3.
