Abstract
In this research, we reported an effective method for the synthesis of a new mesoporous triazine-based carbon (MTC) substrate and its application as the green and recoverable catalyst in the synthesis of organic compounds. The porous carbon acted as a substrate for silver active species after its surface modification by chloroacetonitrile (Ag@MTC). The Ag@MTC nanocatalyst was characterized by several techniques namely, Fourier-transform infrared spectroscopy, field emission scanning electron microscopy with energy dispersive spectroscopy, X-ray diffraction, transmission electron microscopy, Brunauer–Emmett–Teller surface area analysis, and inductively coupled plasma. The Ag@MTC catalyst was applied for the reduction of nitroaromatic compounds in aqueous media by using NaBH4 (reducing agent) at room temperature. This nanocatalyst can be readily recovered and recycled for at least nine runs without a notable decrease in its efficiency. Catalytic efficiency studies exhibited that Ag@MTC nanocatalyst had good activity towards reduction reactions.

Summary
Surface and so diminishing the catalytic activity. To defeat this problem, nanoparticles are stabilized on numerous solid supports this issue improves the availability of their surface, and the catalyst recovery. Using the carbon mesoporous materials are widely applied as catalytic support materials due to inexpensive, great specific surface area, simple synthesis process, good chemical and thermal stability, and tunable morphological s tructures. Modifying the surface of various carbon materials such as graphite, graphene, porous carbon, carbon nanotubes, nanowires, and fullerenes can chemically create new applications by improving the properties. A solution of 3.0 g chloroacetonitrile in 4.0 mL of isopropanol was prepared and added to the first mixture and stirred at 65 °C for 12 h. After this time, the reaction was complete by addition ethanol (70%) to the above solution and the product was separated by centrifugation and washed three times with ethanol (70%). 5.0 mL absolute ethanol was added to the above mixture and dried for 12 h at 65 °C
