Phan, Thanh Truong Department of Chemical Engineering, HCMC University of Technology, VNU-HCM, 268 Ly Thuong Kiet, District 10, Ho Chi Minh City, Viet Nam ar ti c l e i nf o ab stra ct Article history: A crystalline delafossite of silver ferrite AgFeO nanoparticles were successfully synthesized by modiﬁed Received 11 September 2017 method. Physical characterizations of the AgFeO catalyst were obtained by several techniques including Revised 22 January 2018 X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy Accepted 15 February 2018 (TEM), thermogravimetric analysis (TGA), X-ray Fluorescence (XRF), and nitrogen physisorption measure- Available online 2 March 2018 ments. The material was applied as active heterogeneous catalyst for decarboxylative ﬂuorination of car- boxylic acids. The optimized conditions utilized the electrophilic Selectﬂuor reagent in acetone/H O Keywords: solvent at room temperature in 3 h. Investigation of structure/activity relationship revealed strong syn- Silver ferrite ergistic effect of iron on silver center. Subsequently,
