Effect of Precursor-Solution pH on the Phase Composition and Microstructure of Precipitated NiO, and By-Product Retention in Hydrothermally Derived NiO–MnO2 Powders

Nickel oxide (NiO)/manganese dioxide (MnO2) composites are widely studied pseudocapacitive electrode materials, but the role of the precursor-solution pH in their synthesis is poorly established. NiO was precipitated at precursor pH 8, 9, 10, and 11, calcined, and subjected to a...
