Carbon dioxide reforming of methane (DRM) reaction has been widely explored since it is a sustainable process to transform carbon dioxide and methane which are the main greenhouse gases to value added synthesis gas. Herein, [email protected] [email protected]₂ core shell hollow spheres ([email protected]@SiO₂ HS) with high carbon resistance for DRM at 600 °C (10.4% weight loss after 50 h reaction) have been designed. Additionally, it also showed stable and high conversions (82.5% and 78.4% for carbon dioxide and methane respectively) and carbon resistance (5.5% weight loss) for DRM reaction at 700 °C within the testing time of 600 h. By contrast, for [email protected] without SiO₂ shell, tremendous carbon nanotubes (CNTs) formed for DRM at 600 °C, even though it is interesting to find that there is slight nickel sintering. TPO-MS, H₂-TPR, XPS and TEM characterizations showed that the interactions between nickel nanoparticles and NiPhy materials were increased due to the coating of SiO₂ shell which also confined nickel and inhibited detaching of nickel from the surface of [email protected]@SiO₂, which eliminates the accumulation of carbon to become CNTs. The synthesis method for core shell HS provides numerous opportunities to design other structured materials such as Ni-M (M = Co, Fe, Mg)@SiO₂ HS for the efficient utilization of greenhouse gases through environmentally sustainable processes.

甲烷的二氧化碳重整（DRM）反应已被广泛研究，因为它是将二氧化碳和甲烷（一种主要的温室气体）转化为增值合成气的可持续过程。在此，设计了[电子邮件保护] [电子邮件保护] _2个核壳空心球（[电子邮件保护] @SiO ₂ HS），在600°C下DRM具有较高的耐碳性（反应50小时后失重10.4％）。此外，在600 h的测试时间内，在700°C下DRM反应也显示出稳定和高的转化率（分别为二氧化碳和甲烷分别为82.5％和78.4％）和耐碳性（失重5.5％）。相比之下，对于没有SiO _2的[电子邮件保护的]在外壳中，在600°C下形成了用于DRM​​的巨大碳纳米管（CNT），尽管有趣的是发现轻微的镍烧结。TPO-MS，H ₂ -TPR，XPS和TEM表征表明，由于SiO ₂壳层的涂层也限制了镍并抑制了镍从[电子邮件保护]的表面脱离，因此镍纳米颗粒与NiPhy材料之间的相互作用增加了。@SiO ₂，消除了碳的积累成为CNT。核壳HS的合成方法为设计其他结构化材料（例如Ni-M（M = Co，Fe，Mg）@SiO ₂ HS ）提供了许多机会，以通过环境可持续的过程有效利用温室气体。
