nanoparticles, PAN nanofibers, and Zn(Ac)
2
/PAN nanofibers:
a) survey spectrum and b) N 1s, c) O 1s, and d) Zn 2p spectra. The chemical bonding states of
Zn(Ac)
2
/PAN nanofibers were investigated by XPS. The full wide-scan spectrum exhibits
strong O and Zn signals from the Zn(Ac)
2
/PAN nanofibers, confirming the presence of
Electronic Supplementary Material (ESI) for Journal of Materials Chemistry A.
