Morphologies and crystal structures of NixCo1-xMoO4 nanowires. (a-e) FE-SEM images of NixCo1-xMoO4 nanowires with various x values and (f) their corresponding X-ray diffraction patterns. Filled circle, empty circle, filled inverted triangle, and empty inverted triangle correspond to α-CoMoO4, β-CoMoO4, α-NiMoO4, and β-NiMoO4, respectively (by KS Park et al.).
