Transformation of β-Ni(OH)2to NiO nano-sheets via surface nanocrystalline zirconia coating: Shape and size retention
نویسندگان
چکیده
Shape and size of the synthesized NiO nano-sheets were retained during transformation of sheet-like b-Ni(OH)2 to NiO at elevated temperatures via nano-sized zirconia coating on the surface of b-Ni(OH)2. The average grain size was 6.42 nm after 600 C treatment and slightly increased to 10 nm after 1000 C treatment, showing effective sintering retardation between NiO nano-sheets. The excellent thermal stability revealed potential application at elevated temperatures, especially for high temperature catalysts and solid-state electrochemical devices.
