摘要

在（NH4）6Mo7O24·4H2O和（NH4 = 0，1，4，8），然后干燥并在H2中还原。CA的加入对甲烷干重整MoP的微观结构（表面积和颗粒分散度）和性能有显著影响。在这些MoP-CAx催化剂中，发现MoP-CA8表现出最高的催化剂稳定性，这应该归因于MoP的抗氧化能力和甲烷离解能力的最佳匹配。

The effect of citric acid on the microstructure and activity of MoP phosphide for dry reforming of methane

A series of MoP catalysts (MoP-CAx) were synthesized by adding citric acid (CA) to solutions of (NH₄)₆Mo₇O₂₄·4H₂O and (NH₄)₂HPO₄ with a fixed molar ratio of Mo:P:CA = 1:1: x (x = 0, 1, 4, 8) followed by drying and reduction in H₂. The addition of CA had a significant effect on the microstructure (surface area and particle dispersion) and performance of MoP for dry reforming of methane (DRM). Among these MoP-CAx catalysts, the MoP-CA8 was found to show the highest catalyst stability, which should be attributed to the best matching of oxidation resistance ability and methane dissociation ability of MoP.
