Welcome to the 2DChem group website

2D-Chem is a cross-disciplinary research group led by Dr. Gonzalo Abellán and focused on the study of two-dimensional (2D) materials combining both inorganic and organic chemistry with materials science. We are part of the Research Team on Molecular Materials at the Institute of Molecular Science (ICMol, University of Valencia, Spain). Furthermore, some members of our group are located at the Joint Institute of Advanced Materials and Processes (ZMP), which belongs to the Friedrich-Alexander Universität Erlangen-Nürnberg (Germany).

Our group works in three main research lines: 2D pnictogens (group of P, As, Sb and Bi), layered hydroxides, and carbon nanoforms and related hybrid materials. Along with the synthesis and exhaustive characterization of our materials, we aim to explore their novel applications in the fields of energy storage and conversion, catalysis, electronics or magnetism, among others.

We have close links with other recognized scientific groups, in both national and international institutions, e.g. University Erlangen-Nuremberg (Germany), Trinity College Dublin (Ireland), ITQ-CSIC (Spain), Universidad Autónoma de Madrid (Spain), IMDEA Nanociencia (Spain), University of Vienna (Austria), Budapest University of Technology and Economics (Hungary), University of Strasbourg (France), Universidad Complutense de Madrid (Spain), The University of Texas at El Paso (USA), and ETH Zurich (Switzerland).

Towards lateral in-plane heterostructures based on layered hydroxides
We are happy to announce that our proposal “Towards lateral in-plane heterostructures based on layered hydroxides” has been approved by the Scientific Review Panel from @ALBAsynchrotron to perform measurements at the beam line BL11-NCD-SWEET. Specifically, we will develop in-situ Small and Wide Angle X-ray Scattering (SAXS-WAXS) measurements in order to identify the chemical tools to obtain these unexplored two-dimentional heterostructures based on layered hydroxides.

New paper published in Advanced Materials Interfaces
In this work we study the noncovalent functionalization of black phosphorus (BP) with tailor made perylene diimides (PDI). By combining both experimental and density functional theory (DFT) calculations, we have designed and fully characterized the organic-inorganic BP-PDI hybrids. The resulting materials depict a denser packing of the PDI molecules on the BP surface, giving rise to an outstanding environmental protection of the BP thanks to the role of the PDI as a passivation layer. This phenomenon leads to an enhancement of both ambient and thermal stabilities in the light of XPS, Raman spectroscopy and TG-MS analysis. Finally, we have studied for the first time field effect transistors (FETs) based on these hybrid materials, leading to an improvement in the electron mobilities thanks to the protecting role of the PDI. In summary, this work points towards the noncovalent functionalization with PDI molecules as a promising approach in the development of stable electronic devices based on 2D-pnictogens.

New article published in Angewandte Chemie
Quantifying the Covalent Functionalization of Black Phosphorus. In this paper, we propose a straightforward method to quantify the overall functionalization degree of covalently modified 2D black phosphorus. This methodology relies on the use of Raman spectroscopy to correlate the Raman modes originated from the covalent grafting with the quantitatively determined functionalization degree calculated by 31P MAS solid state NMR spectroscopy. Since Raman spectroscopy is one of the most powerful characterization tools in materials chemistry, as evidenced by graphene research, these results will foster the progression in the field of 2D BP research. Especially for the quick evaluation of alternative functionalization protocols the presented correlation method could be of great use to determine the efficiency of the chosen reaction pathway.

New paper published in Chemical Science.
In this new work we study the low-temperature formation mechanism of NiFe-carbon magnetic supercapacitive nanocomposites prepared using hybrid sebacate intercalated layered double hydroxides (LDHs) as precursors with complementary in situ (temperature-dependent) techniques. These in situ studies confirm the early formation of FeNi3 nanoparticles at ca.200–250 °C, preceding the concerted collapse of the starting NiFe-LDH laminar structure over just 50 °C. In addition, the catalytic interactions between the metallic atoms and the organic molecules form a graphitic carbon matrix leading to the formation of the final FeNi3-carbon nanocomposite. This report provides fundamental insights into the catalytic formation of carbon-based nanocomposites using LDHs as precursors, allowing better tuning of their final properties, with special interest in the field of energy storage and conversion.
