As proven in Fig. 9, the catalyst VPOC5 shows the best glycerol conversion, accompanied by extraordinarily low acrolein selectivity and Premium Vapor carbon balance. Furthermore, based on the carbon balance analysis, it was observed that the decrease in acrolein selectivity at elevated temperatures primarily resulted from an augmentation in carbon deposition. Furthermore, the catalyst VPOC6 prepared with 1,6-diaminohexane exhibits the best surface acid site density and catalytic exercise due to increased acidity ensuing from the presence of variable V species together with plentiful OV and quite a few hydroxyl groups,39 thereby enhancing the selectivity towards the specified product.
First, these defects enhance surface acid site density through undercoordinated metallic centers, considerably enhancing adsorption capability for Vapor Sale oxygenated substrates resembling alcohols and carboxylic acids.41 Second, the OV induce digital redistribution at catalyst surfaces, particularly elevating the p-orbital vitality states of adjacent oxygen atoms.42 This digital perturbation enhances the nucleophilic character at energetic websites, vapor sale thereby facilitating both α-hydrogen abstraction and ketene intermediate stabilization throughout the speed-limiting steps.
