Description: PXRD of Co3O4 kindly provided by Dr. Georg Bendt. The PXRD patterns were recorded on a Bruker D8 Advance powder diffractometer using Bragg-Brentano geometry at room temperature with Cu Kα radiation (λ = 1.5418 Å, 40 kV, and 40 mA). The powder samples were examined in the range between 5 ° and 90 ° (2θ) with a step size of 0.01 ° (2θ).

SampleThe nanoparticles were provided from the Schulz-Group. Synthesis description: For the synthesis of spherical Co3O4 nanoparticles, 1.164 g Co(NO3)2·6 H2O (4.0 mmol) was dissolved in 200 mL water in an open reactor vessel. Subsequently, 3.24 mL of ammonium hydroxide solution and 240 µL of H2O2 were added. The black reaction mixture was then heated to 60 °C for 15 minutes. A solution containing 0.58 g Co(NO3)2·6 H2O (2 mmol) dissolved in 80 mL water was added and the reaction temperature was maintained at 60 °C for 3 hours. After cooling to room temperature, the nanoparticles were collected by centrifugation at 3000 rpm, washed with water and acetone and dried in air. The particles were then heated at a rate of 4.5 °C min-1 to 300 °C, where the temperature was maintained for 15 minutes before cooling to room temperature.
