摘要

建立了一种在水热条件下合成K2Ce(PO4)2·xH2O(空间群I41/amd， A = b = 6.8300(2) Å， c = 17.8488（4) Å， V = 832.63(4) Å3, Z = 4）的新方法。结果表明，该化合物的热解过程经历了三个失重阶段，中间产物为CePO4和K4P2O7，中间产物经进一步加热形成CePO4和K3Ce(PO4)2的混合物。K2Ce(PO4)2·xH2O的防晒系数和UV-A防护系数计算值分别为2.1和2.0。K2Ce(PO4)2·xH2O对人角质形成细胞系（HaCaT）有光保护作用。首次评价了KCe2(PO4)3和K2Ce(PO4)2·хH2O在亚甲基蓝分解反应中的光活性。当使用K2Ce(PO4)2·хH2O时，有机染料的分解反应明显减慢。

Hydrothermal Synthesis of K2Ce(PO4)2·хH2O and Analysis of Its Photoprotective Properties

A new method for obtaining K₂Ce(PO₄)₂·xH₂O (space group I4₁/amd, a = b = 6.8300(2) Å, c = 17.8488(4) Å, V = 832.63(4) Å³, Z = 4) under hydrothermal conditions has been developed. It has been established that the thermolysis of this compound proceeds through three stages of mass loss with the formation of CePO₄ and K₄P₂O₇ as intermediate products, which upon further heating form a mixture of CePO₄ and K₃Ce(PO₄)₂. The calculated values of the sun protection factor and UV-A protection factor for K₂Ce(PO₄)₂·xH₂O were 2.1 and 2.0, respectively. In relation to the human keratinocyte cell line (HaCaT), a photoprotective effect of K₂Ce(PO₄)₂·xH₂O was recorded. For the first time, the photoactive properties of KCe₂(PO₄)₃ and K₂Ce(PO₄)₂·хH₂O in the decomposition reaction of methylene blue were evaluated. A significant slowdown in the decomposition reaction of an organic dye was demonstrated when using K₂Ce(PO₄)₂·хH₂O.
