Sustainable transformation of methane into methanol feedstock syngas is a promising direction in future energy generation. A monolithic SiC-foam (SiC-foam, denoted as SCf) supported structured Ni-SrO composite nanomaterial was prepared via reducing the SrNiO₃ perovskite. The Ni-SrO/SCf displays a stronger resistance to Ni-sintering/coke-deposition than the unmodified Ni/SCf due to its uniform Ni distribution as well as the strong Ni-SrO interaction. In the presence of Ni-SrO/SCf sample at a gas hourly space velocity (GHSV) of 24,000 mL_CH4CO2 g_Cat⁻¹ h ^− 1 and an operating temperature of 850 °C, the initial conversion rate of biogas (CH₄/CO₂) was 70/94%, which gradually dropped to 55/72% within 40 h, but its activity remained stable for the next 60 h. By contrast, the conversion rate of biogas (CH₄/CO₂) in the presence of Ni/SCf sample was decreased rapidly from 60/80 to 50/65% within 20 h, due to the severe coke deposition and Ni-sintering.

将甲烷可持续转化为甲醇原料合成气是未来能源生产的一个有前途的方向。通过还原 SrNiO ₃钙钛矿制备了单片 SiC 泡沫（SiC 泡沫，表示为 SCf）负载的结构化 Ni-SrO 复合纳米材料。由于 Ni-SrO/SCf 均匀的 Ni 分布以及强的 Ni-SrO 相互作用，Ni-SrO/SCf 比未改性的 Ni/SCf 显示出更强的抗 Ni 烧结/焦炭沉积的能力。在 Ni-SrO/SCf 样品的存在下，气时空速 (GHSV) 为 24,000 mL _{CH4 CO2} g _Cat ^-1 h  ^{-  1}且操作温度为 850 °C，沼气的初始转化率 (CH ₄ / CO ₂) 为 70/94%，在 40 小时内逐渐下降到 55/72%，但其活性在接下来的 60 小时内保持稳定。相比之下，由于严重的焦炭沉积和 Ni 烧结，在 Ni/SCf 样品存在下沼气的转化率（CH ₄ /CO ₂）在 20 小时内从 60/80 迅速下降到 50/65%。
