Scanning electron microscopy (Sigma 300, Zeiss, Oberkochen, Germany) was employed for evaluating the surface morphology of SS-SNEDDS. Lyophilized powder was deposited on a glass coverslip, which was previously adhered using carbon tape attached to a metallic stub. This was then air-dried and further metalized with gold coating using a vacuum sputter. This sample was then analyzed using SEM (Sigma 300, Zeiss, Oberkochen, Germany).

The chemical bond structures of the synthesized composites were examined using the transmittance mode with Fourier transform infrared spectroscopy (FTIR, VERTEX 70V) in the range of 4000–500 cm−1. Crystal structure analysis was determined by X‐ray diffractometry (XRD, PANalytical Empyrean) using Cu‐Kα (1.5418 Å) radiation between 10 and 90°, and morphology analysis were determined by scanning electron microscope (SEM, Zeiss Sigma 300). Energy dispersive X‐ray spectroscopy (EDS, Zeiss Sigma 300) was used for the quantitative analysis of the elements. The optical properties were determined using a UV–Vis–NIR spectrophotometer (Shimadzu UV‐3600 Plus) in transmittance mode between 200 and 800 nm wavelength. The thermal analysis of the composites was investigated in an air atmosphere with a heating rate of 10 K min−1 using an aluminum pan at 28–1000 °C using the 409PC/PG model (NETZSCH STA).

AFM (Bruker multimode 8) was used to measure the thickness and transverse diameter of GO. The AFM analysis was conducted using a drop of dialyzed GO solution, which had been diluted and ultrasonicated for 1 h on a mica substrate. The prepared LS–rGO and rGO solutions were dropped on a copper sheet and observed through SEM (Zeiss Sigma 300, Germany) after the solvent was completely dried to contrast the surface morphology and the folding degree. The Raman spectra of the freeze-dried LS–rGO and rGO samples were recorded on a Senterra R200-L apparatus (Bruker Optics) with an excitation wavelength of 532 nm. The FT-IR measurements (Bruker tensor II) were performed in the wavenumber range of 680–4000 cm−1 to explore the chemical structure of the freeze-dried LS–rGO and rGO samples. The XPS analysis was performed on a Thermo Scientific K-Alpha photoelectron spectrometer using Al Kα (1486.6 eV) radiation.
All electrochemical measurements were performed on an electrochemical workstation (CHI-760E, Austin, Texas) with a standard three-electrode system, as shown inFig. 1a . Details can be found in the ESI.†

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.
