水滑石-石墨烯复合物用于CO甲烷化
LDH-graphene Compositions for CO Methanation
摘要
Abstract
Layered double hydroxide (LDH)-graphene compound was prepared as a precursor for CO methanation. Due to its high thermal conductivity,graphene was used in this research to improve the catalytic anti-sintering property. The results showed that most LDH adhered to the graphenen in the Ni-Al2O3/5%rGO catalyst,but some LDH was covered by graphene layers with large surface area,which caused the crystallinity decrease. After reduction,some of the active particles may be enveloped and could not take part in the reaction of CO methanation. Ni-Al2O3/5%rGO showed inferior catalytic perform-ance,but its thermal stability improved obviously. During the stability test,CO conversion of Ni-Al2O3/5%rGO maintained at 100%for 50 h.关键词
