Climate change, greenhouse gas emissions and energy demand are actually calling for new methods to manage better carbon-containing compounds. In particular, the valorization of CH₄ and CO₂ by dry reforming of methane may both abate pollution and produce a syngas with a H₂/CO ratio close to 1, which is advantageous for industrial applications, and is a cheaper and cleaner alternative to fossil fuels. Yet this process has limitations such as secondary reactions and catalyst deactivation by carbon deposition. Ni-based catalysts with enhanced activity and high resistance against carbon deposition are therefore actually under investigation. Here we present the first use of Ni–ceria-based fibers synthesized by solution blow spinning, as catalyst to produce syngas used by the dry reforming reaction. Catalyst stability was tested at 700 °C. Our results show no significant deactivation after 30 h on stream. Thermal analysis and X-ray diffraction of the spent catalyst reveal that the deposited carbon species did not alter the stability of the catalyst. Overall, findings show that solution blow spinning is a promising technique to produce low-cost nickel fibers and anti-sintering, carbon-resistant, and stable fibrous materials for CO₂ reforming of methane.

气候变化，温室气体排放和能源需求实际上正在要求采用新方法来管理更好的含碳化合物。特别地，通过甲烷的干重整来重整CH ₄和CO ₂既可以减轻污染，又可以产生具有H ₂的合成气。/ CO比接近1，这对于工业应用是有利的，并且是化石燃料的更便宜和更清洁的替代品。然而该方法具有局限性，例如二次反应和通过碳沉积使催化剂失活。因此，实际上正在研究具有增强的活性和高抗碳沉积性的镍基催化剂。在这里，我们介绍了通过溶液吹纺合成的镍铈纤维的首次使用，作为催化剂来生产干重整反应所用的合成气。在700℃下测试催化剂稳定性。我们的结果表明，运行30小时后，没有明显的失活。废催化剂的热分析和X射线衍射表明，沉积的碳物质不会改变催化剂的稳定性。总体，₂甲烷重整。
