Ni_0.4Cu_0.6/POM光催化氨硼烷水解制氢性能研究

摘要: 采用溶剂热法合成载体含环磷腈聚合物（POM），再以Ni和Cu作为活性组分通过浸渍还原法负载到载体上，制备出Ni_0.4Cu_0.6/POM催化剂，并将其用于光催化氨硼烷（AB）水解制氢反应。通过TEM、XRD、XPS、FT-IR、UV-vis DRS、PL、EIS等手段对催化剂进行表征，实验结果表明，Ni_0.4Cu_0.6/POM催化剂具有稳定的球形颗粒结构，在298 K、光照的条件下催化反应的TOF值为1461.0 h⁻¹，是非光条件下的1.6倍，并且在经过20次循环后依然保持着良好的催化活性。

Abstract: Ni and Cu were used as active components in the impregnation reduction process to create the Ni_0.4Cu_0.6/POM catalyst after supported cyclophosphazene polymer (POM) was manufactured by solvothermal technique. Hydrogen was produced through photocatalytic hydrolysis of ammonia borane using the catalyst. The catalysts were evaluated using a variety of techniques, including TEM, XRD, XPS, FT-IR, UV-vis DRS, PL, and EIS. The Ni_0.4Cu_0.6/POM catalyst exhibits a stable spherical particle structure, according to the experimental results. After 20 cycles, the catalytic reaction still exhibits good catalytic activity with a TOF value of 1461.0 h⁻¹ under 298 K and light circumstances, which is 1.6 times that under non-light conditions.
