Background  During liquid-phase synthesis of γ-Fe 2 O 3  nanoparticles by chemically induced transition in FeCl 2  solution, enhancement of surface modification by adding ZnCl 2  was attempted by using NaOH. By using transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, energy-dispersive X-ray spectrometry, and vibrating sample magnetometry, the dependence of the synthesis on the amount of additional NaOH was studied.    Results  The experimental results show that the surface of the γ-Fe 2 O 3  nanoparticles could be modified by adding ZnCl 2  to form composite nanoparticles with γ-Fe 2 O 3 /ZnFe 2 O 4  ferrite core coated with Zn(OH) 2  and adsorbed FeCl 3 , and that modification could be enhanced by adding NaOH.    Conclusions  In the experimental conditions, when the concentration of additional NaOH was below 0.70 M, the amounts of ZnFe 2 O 4  and Zn(OH) 2  phases increased slightly and that of adsorbed FeCl 3  was unchanged. When the concentration of NaOH exceeded 0.70 M, the amount of FeCl 3 , ZnFe 2 O 4 , and Zn(OH) 2  increased.
