通过将 NiC2O4 水热生长到泡沫镍上，并随后进行（草酸铌铵）改性和煅烧，开发了一种从纳米到宏观尺度的 Nb2O5-NiO/泡沫镍催化剂，该催化剂对于乙烷氧化脱氢制乙烯具有高活性/选择性和稳定性。 Nb2O5 块对 NiC2O4 衍生的 NiO 纳米棒的外部和部分覆盖，加上泡沫结构增强的传热，对于高效乙烯生产至关重要。
A Nb2O5–NiO/Ni-foam catalyst engineered from nano- to macro-scale is developed by hydrothermal growth of NiC2O4 onto a Ni-foam and subsequent (niobium ammonium oxalate)-modification and calcination, which is highly active/selective and stable for the oxidative dehydrogenation of ethane to ethylene. External and partial coverage of the NiC2O4-derived NiO nanorods with Nb2O5 lumps, coupled with a foam-structure enhanced heat transfer, is paramount for high-efficiency ethylene production.
