“…The binding sites were observed by electrostatic potential diagrams to obtain stable monomers. 34,56 According to Table 1 As demonstrated, the red region represents a negative electrostatic potential value, indicating that it is easier to give electrons and is more nucleophilic than the other regions. Conversely, the blue region represents a positive electrostatic potential and is more likely to give electrons being more electrophilic than the other regions.…”

“…Here, heterogeneous catalysts offer advantages over single metals in terms of their postuse recycling and reuse. 8,9 Other than the existing published catalysts, a latent avenue to boost the selectivity and conversion of the process is to bring in an efficient and stable catalyst carrier, [10][11][12][13] and again, activated carbon-loaded rhodium, 14,15 platinum, 16,17 and rubidium 18,19 are among the more studied catalysts, showing equally ne results. Nevertheless, hydrogenation catalysts, such as Ni-B, can affect the process efficiency.…”

“…Previous studies have shown that the α-pinene hydrogenation reaction is a quasi primary reaction. [52][53][54] The kinetic curves of α-pinene hydrogenation reaction at different temperatures are shown in Figure 10a. It can be seen that ln c a is linearly related to time t, where c a is the concentration of α-pinene at a certain moment, to obtain the rate constants (k)…”

N-doped mesoporous carbon spheres (NHMC@mSiO 2 ) encapsulated in silica shells were prepared by emulsion polymerization and domain-limited carbonization using ethylenediamine as the nitrogen source, and RuÀ Ni alloy catalysts were prepared for the hydrogenation of α-pinene in the aqueous phase. The internal cavities of this nanomaterial are lipophilic, enhancing mass transfer and enrichment of the reactants, and the hydrophilic silica shell enhances the dispersion of the catalyst in water. N-doping allows more catalytically active metal particles to be anchored to the amphiphilic carrier, enhancing its catalytic activity and stability. In addition, a synergistic effect between Ru and Ni significantly enhances the catalytic activity. The factors influencing the hydrogenation of α-pinene were investigated, and the optimum reaction conditions were determined to be as follows: 100 °C, 1.0 MPa H 2 , 3 h. The high stability and recyclability of the RuÀ Ni alloy catalyst were demonstrated through cycling experiments.
