甲烷干重整制合成气反应水滑石衍生Ni基催化剂的研究进展
Research progress of hydrotalcite-derived Ni-based catalysts in methane dry reforming to syngas
摘要
Abstract
Methane dry reforming is a reaction that utilizes two greenhouse gas(CH4 and CO2)to generate high value-added syngas,which is of great significance for mitigating greenhouse gas emissions and enhancing the utilization of CH4 and CO2.Ni-based catalysts are the common used catalysts in methane dry reforming reaction,but they suffer from problems such as carbon deposition and sintering,which can lead to catalyst deactivation.Due to the large specific surface area and adjustable acidity and composition,hydrotalcite-derived Ni-based catalysts are widely used in methane dry reforming reaction.Firstly,the mechanism of methane dry reforming reaction and deactivation mechanism of catalysts were systematically discussed.Next,the synthesis of hydrotalcite-derived Ni-based catalysts and their application in methane dry reforming reaction were comprehensively illustrated,and the effect of the compositions,additive components and preparation methods and conditions on the resistance to carbon deposition and sintering performance of hydrotalcite-derived Ni-based catalysts were analyzed.Finally,from the aspects of Ni-based nano/single atom catalysts,few-/mono-layered hydrotalcite-derived Ni-based catalysts and hydrotalcite-derived Ni-based multi-functional catalysts,the research direction of hydrotalcite-derived Ni-based catalysts in methane dry reforming reaction were proposed,which can provide further insightful guidance for the development of efficient and stable Ni-based nano/subnano-catalysts for the catalytic conversion of C1 molecules(CH4,CO2,etc.).关键词
