Fabrication of wormhole-like YSZ and Ni-YSZ by the novel soft-hard template CTAB/NaCl-assisted route. Suppressing Ni coalescence in SOFC

Nanotechnologies in ceramic electrochemical cells

“…For example, Błaszczak et al developed a one-pot synthesis route in the preparation of porous YSZ and Ni–YSZ particles. 203 The author claimed that a wormhole-like framework with the generation of Ni NPs was realized. The decrease of the particle sizes in the electrode, high homogeneity, a well developed TPB, and an improved interfacial interaction between Ni and YSZ were regarded as the favourable factors that were very helpful for improving the fuel electrode properties.…”

Highly Dispersed Ni over a YSZ Anode Anchored by SiO2 at High Temperature through Low-Temperature Chemical Vapor Deposition

“…The NiO/YSZ nanopowders of about 100 nm in diameter were prepared via co-precipitation followed with hydrothermal treatment, and the maximum power density showed an increment of about 19% than a conventional anode due to the increased TPB length. The porous Ni/YSZ material with wormhole-like structures was prepared through co-precipitation assisted by CTAB/NaCl . The interaction between Ni and YSZ species limited the growth of Ni grains during redox, which resulted in better long-term microstructural stability.…”

“…The porous Ni/ YSZ material with wormhole-like structures was prepared through co-precipitation assisted by CTAB/NaCl. 10 The interaction between Ni and YSZ species limited the growth of Ni grains during redox, which resulted in better long-term microstructural stability. Although the synthetized Ni-based anodes exhibit high improvement of electrochemical performance, post-treatment of commercial YSZ will also be important for practical applications due to the convenient raw materials.…”
