Last day of 2025: Happy to see our latest work on Graphene oxide and Xanthenes hybrids just published on-line in ACS Applied Materials and Interfaces. It is a result of a fruitful collaboration with IACYS group from Univ. Extremadura. The publication is entitled "Graphene Oxide–Enamino-Xanthene Charge-Transfer Hybrids as High-Performance Sensitizing Interfaces for TiO2 Photoanodes" and freely available at

Also fully Open Access now our article "Carbon nanomaterials-Based Inks and Electrodes Using Chitin Nanocrystals",
ACS Sustainable Chemistry & Engineering 2024, 12, 15980-15590:

Dispersing 1D carbon nanomaterials (CNMs) for film processing traditionally relies on surfactants or organic solvents. These methods, however, raise environmental concerns and can negatively impact the final properties of the CNMs. In this work we demonstrate that chitin nanocrystals (ChNCs) synthes...

Contributing to sustainable device components, it's great to see our work on "Carbon nanotube film electrodes enabled by nanostructured biopolymers through aqueous processing" being published in PCCP. It's freely available under https://doi.org/10.1039/d5cp01536g. Enjoy reading.

Processing carbon nanotubes (C**s) into conductive films via liquid-phase is highly attractive for the fabrication of electronic and electrochemical device components. However, conventional deposition methods usually suffer from several limitations, including environmental concerns, loss of intrinsi...

Our latest publication is out: "Fabrication of a-Fe2O3 Nanoparticles/g-C3N4 Direct Z-Scheme Heterojunction of Durable Photocatalytic Activity".
Nice collaboration between our group at ICB-CSIC, Univ. Antwerp, INMA-CSIC-UniZar, Argonne National Lab.
The article is freely available at https://pubs.acs.org/doi/10.1021/acsanm.5c00991.
Enjoy.

The fabrication of a nanohybrid photocatalyst that combines α-Fe2O3 nanoparticles with graphitic carbon nitride (g-C3N4) is reported. The ensuing direct Z-scheme heterojunction greatly boosts the photocatalytic activity of the α-Fe2O3/g-C3N4 nanohybrids. This results in organic dye degradation rat...
