    • Aqueous miscible organic solvent treated NiTi layered double hydroxide De-NOx photocatalysts 

      Pastor, Adrián; Chen, Chunping; Miguel, Gustavo de; Martín, Francisco; Cruz-Yusta, M.; Buffet, Jean-Charles; O'Hare, Dermot; Pavlovica, Ivana; Sánchez Granados (Elsevier, 2021)
      New efficient photocatalysts are required to remediate polluted urban atmospheres. We prepared a series of highly dispersed aqueous miscible organic (AMO) solvent treated NiTi layered double hydroxide (NixTi-AMO-LDHs (x = ...

    • Designing a NiFe-LDH/MnO2 heterojunction to improve the photocatalytic activity for NOx removal under visible light 

      Oliva, M.A.; Giraldo, David; Almodóvar, Paloma; Martín, Francisco; López, María Luisa; Pavlovic, I.; Sánchez Granados, Luis (Elsevier, 2024)
      2D/2D heterojunctions between ultrathin NiFe-CO3 layered double hydroxide (LDH) and varying amounts of birnessite (δ-MnO2) were prepared using an environmentally friendly and cost-effective self-assembly method. The prepared ...

    • Effects of Fe3+ substitution on Zn-Al layered double hydroxides for enhanced NO photochemical abatement 

      Pastor, Adrián; Rodríguez-Rivasa, Fredy; Cruz-Yusta, M.; Martín, Francisco; Pavlovic, I.; Sánchez Granados, Luis; Miguel, Gustavo de (Elsevier, 2020)
      In this work the ability of ZnAlFe-CO3 layered double hydroxides (LDHs) as highly efficient UV-Vis light photocatalysts for the photochemical oxidation of NO gas was studied. LDHs with 3.5 to 4.1 M2+/M3+ and 0.33 to 1.55 ...

    • Use of LDH- chromate adsorption co-product as an air purification photocatalyst 

      Nehdi, A.; Frini-Srasra, N.; Miguel, Gustavo de; Pavlovic, I.; Sánchez Granados, Luis; Fragoso, J. (Elsevier, 2022)
      This work deals with the use of layered double hydroxides for a double environmental remediation. The residue obtained in the use of these materials as a chromate sorbent in water, was subsequently studied as a photocatalyst ...

    • Zn-Al layered double hydroxides as efficient photocatalysts for NOx abatement 

      Rodríguez-Rivas, F.; Pastor, Adrián; Barriga, C.; Cruz-Yusta, M.; Sánchez Granados, Luis (Elsevier, 2019)
      In this study,we report that layered double hydroxides (LDH) exhibited high photocatalytic activitiesin degrading NOx gases for the first time. ZnAl-CO3LDHs with a 1.5 to 3.0 Zn/Al ratio were prepared by ...

    • ZnO on rice husk: a sustainable photocatalyst for urban air purification 

      Pastor, Adrián; Balbuena, J.; Cruz-Yusta, M.; Pavlovic, I.; Sánchez Granados, Luis (Elsevier, 2019)
      A cost-effective and sustainable De-NOx photocatalyst is prepared usingzinc acetate and rice husk. ZnO@SiO2samples are obtained from the calcination of a homogenised precursor mixture at 600 C. ZnO ...
