Clearing Up Discrepancies in 2D and 3D Nickel Molybdate Hydrate Structures.

ABSTRACT: When electrocatalysts are prepared, modification of the morphology is a common strategy to enhance their electrocatalytic performance. In this work, we have examined and characterized nanorods (3D) and nanosheets (2D) of nickel molybdate hydrates, which previously have been treated as the same material with just a variation in morphology. We thoroughly investigated the materials and report that they contain fundamentally different compounds with different crystal structures, chemical compositions, and chemical stabilities. The 3D nanorod structure exhibits the chemical formula NiMoO₄·0.6H₂O and crystallizes in a triclinic system, whereas the 2D nanosheet structures can be rationalized with Ni₃MoO_5-0.5x(OH)_x·(2.3 - 0.5x
