Biomimetic 1-Aminocyclopropane-1-Carboxylic Acid Oxidase Ethylene Production by MIL-100(Fe)-Based Materials Fandzloch, Marzena Rodríguez Maldonado, Carmen Rodríguez Navarro, Jorge Andrés Barea Martínez, Elisa María Metal organic framework Hydroxyapatite Hybrid material Catalysis Agriculture The Spanish Ministry of Economy and Competitivity and UE Feder Program (project CTQ2017- 84692-R), University of Granada (MF, Programa de Estancias de Investigadores Extranjeros en Departamentos e Institutos) and University of Granada-Junta de Andalucía (Operative Program Feder Andalucía 2014-2020, project: B-FQM-364-UGR18), are gratefully acknowledged for generous funding. This study was partially supported by the “Unidad de Excelencia de Química Aplicada a Biomedicina y Medioambiente” (University of Granada). A novel core@shell hybrid material based on biocompatible hydroxyapatite nanoparticles (HA) and the well-known MIL-100(Fe) (Fe3O(H2O)2F(BTC)2·nH2O, BTC: 1,3,5-benzenetricarboxylate) has been prepared following a layer-by-layer strategy. The core@shell nature of the studied system has been confirmed by infrared, X-ray powder diffraction, N2 adsorption, transmission electron microscopy imaging, and EDS analyses revealing the homogeneous deposition of MIL-100(Fe) on HA, leading to HA@MIL-100(Fe) rod-shaped nanoparticles with a 7 nm shell thickness. Moreover, both MIL-100(Fe) and HA@MIL-100(Fe) have demonstrated to act as efficient heterogeneous catalysts toward the biomimetic oxidation of 1-aminocyclopropane-1-carboxylic acid into ethylene gas, a stimulator that regulates fruit ripening. Indeed, the hybrid material maintains the catalytic properties of pristine MIL-100(Fe) reaching 40% of conversion after only 20 min. Finally, the chemical stability of the catalyst in water has also been monitored for 21 days by inductively coupled plasma-mass spectrometry confirming that only ca. 3% of Ca is leached. 2025-01-27T13:48:03Z 2025-01-27T13:48:03Z 2019-08-30 journal article Published version: Fandzloch, Marzena et al.
