合成了镍氧化物-氧化钇稳定的氧化锆（NiO-YSZ）纳米复合材料颗粒，并使用摩擦型研磨设备将其沉积在致密的YSZ基底上。利用该纳米复合粒子成功地制备了具有高比表面积（≤ 10 m2/g）的NiO-YSZ纳米复合多孔薄膜。在该沉积中，纳米复合材料颗粒被机械分散在空气中，导致它们的细聚集体（尺寸约100 nm）。然后，将它们机械冲击在基底上（碰撞速度，~30 m/s）。通过对纳米复合膜的烧结，形成了精细的三维NiO-YSZ网络结构，其还原后的Ni-YSZ多孔膜显示出优异的SOFC阳极性能。
Nikel oxide–ytttria stabilized zirconia (NiO–YSZ) nanocomposite particles were synthesized and deposited on a dense YSZ substrate using an attrition‐type milling apparatus. The NiO–YSZ nanocomposite porous films were successfully fabricated from the nanocomposite particles with high specific surface areas (≫10 m2/g). In this deposition, the nanocomposite particles were mechanically dispersed in air, resulting in their fine aggregates (~100 nm in size). Then, they were mechanically impacted on the substrate (collision speed, ~30 m/s). By the subsequent sintering of the nanocomposite film, the finely constructed three dimensional NiO–YSZ network structure was formed, and its reduced Ni–YSZ porous film showed an excellent SOFC anode performance.
