Synthesis of sulfuric acid nanocatalysts stabilized on the Nanostructures of carbon and itscatalytic property in the esterification process.

Sulfuric acid plays a direct or indirect role in the production of almost all manufactured goods thathumans use today. As a result of such widespread industrial use, large volumes of sulfuric acid waste aregenerated annually, posing severe environmental hazards. Although sulfuric acid recovery is technically possibleand even used on an industrial scale, such processes are very expensive and therefore cannot be considered asa long-term solution as green chemistry. The aim of this study was to stabilize sulfonic acid on the carbon surfaceand after initial studies on the acidity and surface stability by various techniques, its catalytic properties as asolid acid in the process of esterification of carboxylic acid with various alcohols, which is of great importance inthe industry, to be examined. Based on this, the GIOMC-SO۳H catalyst was synthesized and then obtained byvarious techniques such as porosity, scanning electron microscopy, Fourier-transform infrared spectroscopy andits acidic was obtained by titration of acid and base. The synthesized nanoparticles were examined in the processof esterification under solvent-free conditions at a temperature of ۵۰ ° C.
