Nova nano sem 450

SEM-EDS images of the composite beads were obtained using an FEI Nova Nano-SEM 450 (Hillsboro, OR, USA) and Zeiss GeminiSEM 300 (Oberkochen, Germany). The phase structural properties of the obtained materials were determined by XRD diffraction patterns in the range of 5° to 70° at a scan rate (2θ) of 2°/min using a Bruker D8 Advance Powder Diffractometer (Cu-Kα radiation) (Billerica, MA, USA). The metal coordination state with the composite beads was analyzed by XPS analysis using ThermoFisher K-Alpha equipment with Al-Kα radiation (hv = 1486.6 eV) (Waltham, MA, USA). FTIR results in the range of 4000–650 cm⁻¹ were obtained using a Thermo-Fisher IS50. The TGA results were from a thermogravimetric analyzer (NETZSCH STA 449F5, Selb, Germany) under air atmosphere from 30 °C to 800 °C at a heating rate of 10 °C/min. The specific surface area, total pore volume, and average pore radius were determined by nitrogen adsorption at −196 °C (outgassing was performed at room temperature) using a Quantachrome Autosorb iQ gas sorption analyzer system (Boynton Beach, FL, USA). A LakeShore Company (Westerville, OH, USA) vibrating sample magnetometer (model 7404) was used to investigate the magnetic properties of the composite sample. A Bruker A300 spectrometer was used to study the reactive oxygen species (ROS) generated in the reaction system.

The template-free electrodeposited Al nanowires were characterized by scanning electron microscopy (SEM, FEI, Hillsboro, OR, USA, NOVA NanoSEM 450 and ZEISS, Oberkochen, Germany, GeminiSEM 500), transmission electron microscopy/high-resolution transmission electron microscopy (TEM/HRTEM, JEOL, Akishima, Japan, JEM-2100 and JEM-2100F) and selected area electron diffraction (SAED, JEOL, Akishima, Japan, JEM-2100 and JEM-2100F).
