Nickel catalysts have been widely used in various industrial processes, including hydrogenation and dehydrogenation reactions. In this study, we report the synthesis of nickel catalysts by coprecipitation method using nickel nitrate and sodium hydroxide as precursors and silica as a support material. The effect of different synthesis parameters, such as the nickel to silica ratio, pH, and temperature, on the morphology and catalytic performance of the nickel catalysts was investigated. The synthesized nickel catalysts were characterized by XRD, SEM, and FTIR techniques. The results showed that the nickel catalysts had a high surface area and uniform distribution of nickel particles. The nickel catalysts exhibited excellent catalytic activity for hydrogenation and dehydrogenation reactions. The superior performance of the nickel catalysts was attributed to the high dispersion of nickel particles on the silica support and the formation of nickel-silica interface. The coprecipitation method was found to be a simple, efficient, and scalable method for the synthesis of nickel catalysts with high catalytic performance. This study provides insights into the design and synthesis of nickel catalysts for various industrial applications.
