摘要：

This work demonstrates a catalytic activity of MXene materials in the isomerization of alpha-pinene. The temperature influence, catalyst content and reaction time on alpha-pinene conversion have been revealed. Furthermore, the selectivity of transformation to appropriate products have been investigated. The multilayered and exfoliated Ti3C2Tx have been examined. Both studied MXene materials were active in alpha-pinene isomerization. However, the exfoliated Ti3C2Tx increased the activity significantly. As a result, an outstanding 100 mol% conversion of alpha pinene in 7 h was achieved. It was observed that at optimal operating conditions and catalyst content the selectivity resulted in similar to 60 mol% toward camphene formation. Additionally, the kinetics of the process has been described. Here, the analysis indicates that the kinetics of alpha-pinene isomerization over MXene samples was described by first-order kinetics. To the best of our knowledge, it is the highest reported selectivity and conversion reported in the current state of the art.
