Fourier transform infrared (FTIR) spectra were collected using a Vertex 70v (Bruker Co., Germany) spectrometer equipped with an attenuated total reflectance (ATR) cell (single bounce diamond; Golden Gate, Specab). Dried and homogenized samples were pressed onto the ATR cell using a sapphire anvil. Absorption spectra were obtained (wavenumbers 600–4000 cm⁻¹, resolution 4 cm⁻¹) in 100 co-added scans recorded under vacuum at room temperature.
The surface composition of the chars was determined via X-ray photoelectron spectroscopy (XPS) equipped with a monochromatic Al Kα source operated at 120 W. The spectra were collected with a Kratos Axis Ultra DLD electron spectrometer and processed with Kratos software. An analyzer pass energy of 160 eV and a pass energy of 20 eV were used for acquiring survey spectra and individual photoelectron lines, respectively. A spectrometer charge neutralization system was used to stabilize the surface potential. The binding energy (BE) scale was referenced to the C 1s line of aliphatic carbon, which was set to 285.0 eV. Using a Ni spatula, powder samples for the analysis were gently pressed into a pellet affixed to a sample holder. The limit of detection (LOD) was ~ 0.1 at. %.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
