Design and Synthesis of a 2D Cu-Coordinated Carbon Nitride Network: A Promising Single-Atom Catalyst for Environmental Applications

paqui 11 septiembre, 2024 11 septiembre, 2024DFT, Molecules, STM

Metal-coordinated networks are promising catalysts for environmental applications like green hydrogen production and pollutant photo-degradation. While traditionally 3D, recent efforts have extended these networks to 2D, though synthesis and stability remain challenging. Using a bottom-up approach, we successfully designed and synthesized a 2D hexagonal carbon nitride Cu-coordinated network by combining…

Unraveling the mechanisms of Thermal Dehydrogenation of n-Octane on Pt(111) at the atomic scale

paqui 18 octubre, 2023 18 abril, 2024DFT, Molecules, STM, Surfaces

In our article published recently in Nanoscale, we focus on the thermal dehydrogenation of n-octane (n-C8H18) on the catalytic Pt(111) surface in ultra-high vacuum. Our results shed light on the mechanisms behind the initial stages of this industrially relevant reaction, paving the way for the design of efficient dehydrogenation catalysts.…

The influence of reaction conditions on the growth of MOFs on surfaces

paqui 28 marzo, 2023 18 abril, 2024DFT, Molecules, STM, Surfaces

The importance of the reaction conditions has been confirmed in this study, where following an on-surface synthesis approach on the same surface and with the same precursor, two different metal-organic frameworks were obtained. The distinction comes from the different synthesis protocol of the controlled growth of both metal-organic nanostructures. Thus,…

Front cover in Chemistry – A European Journal!

Host-guest interactions are of paramount importance in supramolecular chemistry and in a wide range of applications. Particularly well known is the ability of cucurbit[n]urils (CB[n]) to selectively host small molecules. We show that the charge transfer and complexation capabilities of CB[n] are retained on the surface of 2D transition metal…

Why individual heptagonal rings are not stable on surfaces?

Graphene nanoribbons, GNRs, – narrow stripes of graphene – are predicted to exhibit attractive electronic properties for the fabrication of nanoscale electronic devices. This 1D material shows semiconducting properties that can be tuned by modifying its length, width, or topology border; but also, with the presence of defects in form…

Dysprosium-directed metallosupramolecular network on graphene/Ir(111) (CHEM. COMMUN. 2021)

The interest in exploiting the unique properties of lanthanides has led to the recent design of two-dimensional coordination networks incorporating f-block elements on metallic surfaces. In order to take this field to the next step of progression, it is necessary to electronically decouple these two-dimensional architectures from the metallic surface…

From high quality packing to disordered nucleation or phase separation in donor/acceptor interfaces: ClAlPc-C60 on Au(111) (PHYS. CHEM. CHEM. PHYS. 2021)

nachomar 24 junio, 2021 24 junio, 2021DFT, Molecules, STM, Surfaces

The dramatic consequences that the orientation adopted by the molecular dipoles, in diverse arrays of chloroaluminum phthalocyanine (ClAlPc) on Au(111), have on the ulterior adsorption and growth of C60 are explored by means of an all scanning probe microscopy approach. The unidirectional downwards organization of the molecular dipoles at the first…
