中文摘要：CO2加氢制甲烷(即"CO2甲烷化")是实现碳中和目标的重要途径。CeO2由于具有丰富的表面氧空位和优异的储氧性能被认为是重要的催化剂载体之一，过渡金属Ni也因为具有优异的催化性能和低廉的价格被广泛应用于催化剂的研究，CeO2和金属Ni结合形成的Ni/CeO2基催化剂在CO2甲烷化反应中展现了良好的应用前景。阐述了Ni/CeO2基催化剂催化CO2甲烷化的机理，介绍了 Ni/CeO2基催化剂制备方法，重点总结了活性中心特征、载体性质、助剂类型和金属-载体相互作用等影响Ni/CeO2基催化CO2甲烷化催化性能的因素，并总结了改性Ni/CeO2基催化剂的催化性能。分析发现，通过对Ni/CeO2基催化剂进行改性，可以调控Ni/CeO2基催化剂的CO2甲烷化催化性能与产物选择性，可为提升其CO2甲烷化催化性能提供新的思路。

外文标题：Research progress on construction of Ni/CeO2-based catalysts and their catalytic performances of CO2 methanation

外文摘要：CO2 hydrogenation to methane(also known as"CO2 methanation")is an important way to achieve the goal of carbon neutralization.CeO2 is considered as one of the most important catalyst supports because of its abundant surface oxygen vacancies and excellent oxygen storage capacity.Transition metal Ni is also widely studied because of its excellent catalytic performance and low price.The Ni/CeO2-based catalysts formed by the combination of CeO2 and metal Ni show good application prospects in CO2 methanation.The reaction mechanisms of Ni/CeO2-based catalysts for CO2 methanation were summarized and the preparation methods of Ni/CeO2-based catalysts were introduced,and the key parameters affecting catalytic performance of CO2 methanation such as the characteristics of active centers,properties of supports,types of additives and metal-support interactions were summarized,and the catalytic performances of Ni/CeO2-based catalysts were also summarized.It is found that by modifying Ni/CeO2-based catalysts,the catalytic performances and product selectivities of Ni/CeO2-based catalysts for CO2 methanation can be regulated,which can provide new ideas for improving their catalytic performances of CO2 methanation.
