Quantitatively calcined MCM-41 (all-silicon, Nankai University Catalyst Factory) was suspended in 30 mL of toluene (>99.5%, Nanjing Chemical Reagent Co., LTD) in a round-bottomed flask, into which 0.6 mL of (3-aminopropyl)trimethoxysilane (APTMS; >97%, Aladdin Reagent (Shanghai) Co., LTD) was cautiously added dropwise. After refluxing for 8 h, the resulting mixed solution was centrifuged to separate the target product from the solvent. The target product was then filtrated carefully first with ethanol and then distilled water; finally, it was dried at room temperature for 12 h.
Toluene
Manufactured by Nanjing Chemical Reagent
Sourced in China
Toluene is an aromatic hydrocarbon solvent with the chemical formula C7H8. It is a clear, colorless liquid with a distinctive benzene-like odor. Toluene has a wide range of industrial applications, including use as a chemical intermediate, a solvent in paints, inks, adhesives, and cleaning agents, and as a component in gasoline.

GO (99.0%) and RGO (98.9%) were purchased from XFNANO Materials Tech (China). GO was prepared by the modified Hammers method (18 (link), 23 ) and was mainly in the form of nanosheets with a diameter of 0.5 to 5 μm and thickness of 0.8 to 1.2 nm (according to the information provided by the manufacturer). RGO was prepared by the reduction of GO using l -ascorbic acid (48 ). All these materials were used without further purification.
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.
