And the article contained the following:
Achieving efficient catalytic conversion over a heterogeneous catalyst with excellent resistance against leaching is still a grand challenge for sustainable chem. synthesis in aqueous solution Herein, we devised a single-atom Pt1/hydroxyapatite (HAP) catalyst via a simple hydrothermal strategy. Gratifyingly, this robust Pt1/HAP catalyst exhibits remarkable catalytic selectivity and catalyst stability for the selective oxidation of C2-C4 polyols to corresponding primary hydroxy acids. It is found that the Pt-(O-P) linkages with strong electron-withdrawing function of PO43- (Pt1-OPO43- pair active site) not only realize the activation of the C-H bond, but also destabilize the transition state from adsorbed hydroxy acids toward the C-C cleavage, resulting in the sharply increased selectivity of hydroxy acids. Moreover, the strong PO43–coordination effect provides electrostatic stabilization for single-atom Pt, ensuring the highly efficient catalysis of Pt1/HAP for over 160 h with superior leaching resistance. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Computed Properties of 473-81-4
