Though nickel phosphides had been used widely to transform biomass into bio-fuel, the impact of support on the crystal formation was not clear. Herein, nickel and phosphides loaded on SiO₂, ZSM-5 and γ-Al₂O₃ were synthesized and the interaction between Ni/P and the supports was studied. Pure Ni₁₂P₅ and pure Ni formed on SiO₂ and γ-Al₂O₃, respectively, whereas the mixture of Ni₁₂P₅ and Ni formed on ZSM-5. The formation of AlPO₄ species was the main factor for the absence of Ni₁₂P₅ on Ni/γ-Al₂O₃ catalyst. Furthermore, the support also had a significant impact on the active phase with different particle size and dispersion, and further affected the performance. The highest fuel yield of 67.3 wt.% was obtained on Ni₁₂P₅/SiO₂ catalyst, which might be attributed to the appropriate acid sites and proper Ni₁₂P₅ size. In addition, the catalysts with Ni₁₂P₅ crystal phase displayed good resistance to coke deposition. The findings are important for clarification of the role of support in nickel phosphide active phase formation and coke deposition.

尽管磷化镍已被广泛用于将生物质转化为生物燃料，但载体对晶体形成的影响尚不清楚。在此，镍和磷化物装上的SiO ₂，ZSM-5和γ-Al系₂ ö ₃的合成和研究的Ni / P和支撑件之间的相互作用。纯Ni ₁₂ P ₅和纯Ni形成在SiO ₂和γ-Al系₂ ö ₃，分别，而Ni的混合物₁₂ P ₅和Ni形成在ZSM-5。的AlPO的形成₄种是为不存在Ni的主要因素₁₂ P ₅上的Ni /γ-Al系₂O ₃催化剂。此外，该载体还对具有不同粒径和分散度的活性相具有显着影响，并进一步影响了性能。在Ni ₁₂ P ₅ / SiO ₂催化剂上获得最高燃料产率为67.3 wt。％，这可能归因于适当的酸位和适当的Ni ₁₂ P ₅尺寸。另外，具有Ni ₁₂ P ₅晶相的催化剂显示出良好的抗焦炭沉积性。这些发现对于阐明载体在磷化镍活性相形成和焦炭沉积中的作用非常重要。
