The present work emphasizes synthesis and evaluation of rice husk (RH) derived nano structured silica material as support for Ni in the catalytic methane cracking (CMC) process. CO chemisorption results showed the 15 wt%Ni/RH-SiO₂ catalyst exhibited a higher ratio of surface decorated Ni sites compared to other Ni loadings. TEM analysis of deactivated catalysts indicated the formation of carbon nano materials (mostly CNT/CNF) along with pure H₂. Raman spectroscopic analysis of the deactivated catalysts exhibited a low proportion of graphitic carbon with a shift at 1320 cm⁻¹ than the amorphous carbon band at 1580 cm⁻¹. The superior performance of Ni supported on SiO₂ was rationalized by H₂-TPR, ²⁹Si MAS NMR, XRD and BET-surface area analyses.

目前的工作重点是合成和评价稻壳 (RH) 衍生的纳米结构二氧化硅材料作为催化甲烷裂解 (CMC) 过程中 Ni 的载体。CO 化学吸附结果表明，与其他 Ni 负载相比，15 wt% Ni/RH-SiO ₂催化剂表现出更高的表面装饰 Ni 位点比率。失活催化剂的TEM 分析表明碳纳米材料（主要是CNT/CNF）与纯H _{2 一起形成}。失活催化剂的拉曼光谱分析表明，石墨碳在 1320 cm ^-1处的位移比例低于 1580 cm ^-1处的无定形碳带。H ₂使负载在 SiO ₂上的 Ni 的优越性能合理化-TPR、²⁹ Si MAS NMR、XRD 和 BET 表面积分析。
