ABSTRACT
The experimental results combined with thermodynamic analysis revealed that the formation of Li3PO4·2ZrSiO4 takes precedence over forming Li3Zr2Si2PO12, due to the relatively low Gibbs-free-energy of the reaction between ZrO2 and SiO2 catalyzed by Li3PO4. This study indicates that developing methods with mild conditions is crucial for the Li3Zr2Si2PO12 preparation.

ABSTRACT
The related reaction scheme to clarify the novelty of this work: In this work, the PtNi/Nb2O5-C bimetallic catalysts are synthesized by the ethylene glycol solvothermal method, which exhibit the evidently increased catalytic performance for alkaline MOR. The electronic effect and the hydroxyl brought from Ni species are mainly ascribed for the enhancement of activity and CO tolerance. -
