While their excellent optoelectronic properties have been successfully applied in photovoltaics, their potential in photocatalysis remains relatively unexplored. Herein, we report a novel humidity‐driven approach for the in situ synthesis of MAPbI3 nanocrystals (NCs) within a nickel acetate matrix, forming a nanocomposite thin film that enhances the system's stability and enables its use in photochemical reactions. UV‐Vis spectroscopy and X‐ray diffraction confirm the rapid and effective synthesis of NCs within the matrix after 1 min at 80% relative humidity (RH). Optimal photoconversion conditions are attained after 60 min of exposure at 80% RH, due to the increased porosity and nanocrystal size over time as revealed by electron microscopy. The MAPbI3‐Ni(AcO)2 nanocomposite exhibits superior photocatalytic activity compared to standard polycrystalline MAPbI3 films for the decomposition of Sudan III under simulated sunlight. Furthermore, the nanocomposite demonstrates good recyclability over multiple cycles. Overall, this work highlights the potential of MHP‐based nanocomposites for solar‐driven catalytic systems in pollution mitigation. info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.7 2024 MATERIALS SCIENCE, MULTIDISCIPLINARY 151 / 461 = 0.328 2024 Q2 T1 ENERGY & FUELS 85 / 182 = 0.467 2024 Q2 T2 1.544 2024 Atomic and Molecular Physics, and Optics 2024 Q1 Energy Engineering and Power Technology 2024 Q1 Electronic, Optical and Magnetic Materials 2024 Q1 Electrical and Electronic Engineering 2024 Q1 10.9 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Farinós-Navajas, Noemi Noguera-Gómez, Jaume Sagra Rodríguez, Víctor Vallés-Pelarda, Marta Momblona, Cristina Universidad de Zaragoza (orcid)0000-0003-2953-3065 Ripolles, Teresa S.
