Transmission electron microscopy (TEM) images were taken using a JEOL 1010 operated at 100 kV. For TEM characterization, samples were dispersed in ethanol via ultrasonication, then dried on the carbon film on a copper grid. Nitrogen sorption analysis was conducted by a Micromeritcs Tristar II 3020 system at 77 K. The samples were degassed at 393 K for 12 h and 453 K for 6 h for MONs and MSNs, respectively, under a vacuum before measurement. The Barrett–Joyner–Halenda (BJH) method was used to calculate the pore size of samples from the adsorption branches of the isotherms, and the Brunauer Emmett–Teller method was utilized to calculate the specific surface areas. The total pore volume was derived from the adsorbed volume at the maximum relative pressure (P/P₀) of 0.99, which attenuated total reflectance Fourier transform infrared spectroscopy (FTIR) analysis was conducted on a Thermo Nicolet Nexus 6700 FTIR spectrometer equipped with Diamond ATR Crystal. A solid-state Bruker Advance III spectrometer was used for ¹³C cross-polarization magic-angle spinning (CPMAS) and ²⁹Si magic angle spinning (MAS) nuclear magnetic resonance (NMR) spectra with 7T (300 MHz for ¹H) magnet, Zirconia rotor, 4 mm, rotated at 7 kHz. The zeta potential was measured three times using a Zetasizer Nano instrument by dispersing particles into deionized water under sonication.

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.
