- Summary:
- Purified nickel and a large number of MgTi2 / NiO2 catalysts with various MgTi2 loadings were produced using the traditional incipient wetness method. X-ray crystallography and Fourier-transform infrared spectroscopy were used to examine the catalysts. To understand the material's microstructure better, the researchers investigated oxygen adsorption at 90K. The amine titration method was used to investigate the acidic characteristics of these catalysts. In a study on cumene cracking, these catalysts were employed. The catalyst was found to be amorphous up to a loading of 12 weight percent MgTi2, but at higher loadings, crystalline MgTi2 phase formed on an amorphous silica substrate. When NiO2 is doped with more MgTi2, there are significant differences in the structure, surface acidity, and catalytic activity of the catalysts. Catalysts with a higher MgTi2 loading are noticeably more acidic than those with a lower MgTi2 loading. A correlation between the amount of cracking activity and the number of acid sites on the catalyst surface has been shown in numerous studies. Cumene cannot be cracked over the investigated catalysts unless the catalyst contains extremely acidic sites. Unmistakably Bronsted acid sites, with the breaking action attributed to a mechanism involving chromium ions. The results were validated by comparing them with relevant studies in the existing literature. These comparisons demonstrate consistency with similar research, confirming the effectiveness of the MgTi2/NiO2 catalysts
