Cheap and robust compounds that can replace precious metal (PM) catalysts are eagerly anticipated for hydrogen-involved chemical transformations. Herein, Ce³⁺ and Ni²⁺ were co-bonded by HPO₄²⁻ in a one-pot solvothermal synthesis system; then, the obtained precipitates were thermal-treated to obtain a series of Ce-Ni-P samples. With characterizations of XRD, XPS, SEM and HRTEM, the samples were featured as nanocomposites and as closely contacted CePO₄ and Ni₂P particles in both ca. 10.0–40.0 nm. Hydrogen adsorption-activation properties comparable to those of precious metals were discovered on the CePO₄ component (H₂-TPD), making a main contribution in achieving the superior TOF of 0.06-0.51 s⁻¹ for hydrogenation of cinnamaldehyde (CAL) to hydrocinnamaldehyde (HCAL), with 92–99% selectivity on (CePO₄)_m/Ni₂P nanocomposites (with molar ratio m of 0.12–4.6). The function of Ni₂P was shown to activate CAL (CAL-TPD); then, a Langmuir–Hinshelwood mechanism was proposed and uncovered from the kinetic measurements. Superior catalytic hydrogenation performances were represented for two phenyl-alkynes and ten other α, β-unsaturated carbonyl compounds, further indicating that CePO₄/Ni₂P nanocomposites serve as general hydrogenation catalysts; the features of low cost, robust structure and comparable properties to PM in both hydrogen activation and hydrogenation activity provide these nanocomposites with the potential to be PM substitutes for boosting correlating hydrogen-involved applications.

人们迫切期望廉价而又健壮的化合物能够替代贵金属（PM）催化剂，用于涉及氢的化学转化。在一锅溶剂热合成系统中，Ce ³⁺和Ni ²⁺通过HPO ₄ ^2-共同键合。然后，对获得的沉淀物进行热处理，以获得一系列的Ce-Ni-P样品。通过XRD，XPS，SEM和HRTEM的表征，样品在两个样品中均具有纳米复合材料的特性，并具有紧密接触的CePO ₄和Ni ₂ P颗粒的特征。10.0–40.0 nm。在CePO ₄组分（H ₂-TPD），对实现将肉桂醛（CAL）氢化为氢肉桂醛（HCAL）的TOF达到0.06-0.51 s ^-1的卓越贡献做出了主要贡献，对（CePO ₄）_m / Ni ₂ P纳米复合材料的选择性为92-99％（摩尔比m为0.12-4.6）。Ni ₂ P的功能可以激活CAL（CAL-TPD）；然后，提出了Langmuir-Hinshelwood机理，并从动力学测量中发现了这一机理。对于两个苯基炔烃和十个其他α，β-不饱和羰基化合物，表现出优异的催化氢化性能，进一步表明CePO ₄ / Ni ₂P纳米复合材料可用作一般的加氢催化剂。低成本，坚固的结构以及在氢气活化和氢化活性方面与PM相当的特性为这些纳米复合材料提供了潜在的PM替代品，从而促进了相关氢应用的发展。
