In this study, bio-based substances (BBS) obtained from composted urban biowaste are used as stabilizersfor the synthesis of magnet-sensitive nanoparticles (NPs). The BBS-stabilized NPs are characterized bymeans of different techniques (FTIR, XRD, SEM, BET analysis, magnetization curves). Additionally, TGAcoupled on-line with FTIR and GC/MS analysis of the exhausted gas are performed in order to simultaneouslyidentify all the degradation products and evaluate the exact composition of such BBS-stabilizedmaterials. Moreover, Fenton-like or photo-Fenton-like experiments carried out at circumneutral pH areperformed in order to evaluate the BBS-functionalized NPs photo-activity towards the degradation of caffeine(taken as model emerging pollutant). The obtained promising results encourage the use of BBS as agreen alternative tool for the preparation of smart materials with enhanced magnet-sensitive properties,also suitable for applications in wastewater purification treatments.
