Recyclable biomimetic Sunflower pollen-based photocatalyst for enhanced degradation of pharmaceuticals  Ortiz, Miquel Gómez, Elvira Serrà i Ramos, Albert Pol·len Gira-sols Fotocatàlisi Pollen Sunflowers Photocatalysis Recent trends in addressing the impending water crisis focus on thedevelopment of innovative water treatment methods. This work utilizes pollenas a core template to synthesize highly efficient onion-like photocatalysts forpollutant mineralization. The study showcases a novel electrochemicalsynthesis method that maintains the structural integrity of pollen, resulting inincreased surface area and enhanced photocatalytic activity. After 90-min ofvisible light irradiation, over 99% mineralization is achieved. These hybridphotocatalysts demonstrate exceptional stability and efficacy in degradingpollutants. The used photocatalysts can be recycled into biopellets with anash content of less than 7% (weight), moisture content of less than 8%(weight), and a calorific value of ≈22.1 ± 0.3 MJ kg−1. Additionally, theresulting ashes serve as effective peroxymonosulphate activators for pollutantmineralization. This process offers sustainable waste management whileminimizing waste production, providing a practical solution for waterpurification. The efficacy of this approach in pollutant removal is underscoredby mineralization rates exceeding 99%. 2024-10-16T07:46:44Z 2024-10-16T07:46:44Z 2024-07-26 2024-10-16T07:46:45Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1613-6810 https://hdl.handle.net/2445/215804 750001 eng Reproducció del document publicat a: https://doi.org/DOI: 10.1002/smll.202405204 Small, 2024, p. 1-13 https://doi.org/DOI: 10.1002/smll.202405204 cc-by (c) Ortiz, Miquel, et al., 2024 info:eu-repo/semantics/openAccess 13 p. application/pdf Wiley-VCH Articles publicats en revistes (Ciència dels Materials i Química Física)
