摘要

二氧化碳甲烷化是碳捕集与利用(CCU)技术的优势工艺之一,可循环利用地球上的碳,减少二氧化碳在大气中的释放和流失。本文采用水热法在低温(130 °C)下合成的 CeO2 纳米棒(r-CeO2)上浸渍 Ni(NO3)2-6H2O 的简便方法制备了 Ni/r-CeO2 催化剂。研究了 Ni 活性相含量和活化条件对 CO2 甲烷化特性和催化性能的影响。使用多种技术对合成催化剂的物理化学特性进行了研究:XRD、EDS、氮吸附等温线、SEM、HR-TEM、H2-TPR、CO2-TPD 和拉曼。催化活性调查和分析表明,镍含量为 15 wt%(15NiCe)的 Ni/r-CeO2 在 600 °C 煅烧 4 小时、450 °C 还原 2.5 小时后性能优异。通过调整铈上的镍含量和改变合成条件,可以获得具有最佳尺寸(∼13.9 nm)、丰富的氧空位和中等强度碱性位点的高度分散的氧化镍颗粒。这就提高了催化活性,使二氧化碳的平衡转化率达到约 90%,在低至 325°C 的温度下对 CH4 的选择性达到 100%。15Ni/r-CeO2 催化剂是一种高活性的二氧化碳甲烷化低温催化剂。

Nickel/ceria nanorod catalysts for the synthesis of substitute natural gas from CO2: Effect of active phase loading and synthesis condition

CO2 methanation is one of the advantageous processes of carbon capture and utilisation (CCU) technologies to circulate the carbon on Earth, mitigating the release and loss of CO2 into the atmosphere. Herein, a Ni/r-CeO2 catalyst was fabricated using a facile method of impregnating Ni(NO3)2·6H2O on CeO2 nanorods (r-CeO2), synthesised by hydrothermal method at low temperature (130 °C). The influence of Ni active phase content and activation condition on the characteristics and catalytic performances in CO2 methanation were investigated. The physicochemical properties of the synthesised catalyst were studied using several techniques: XRD, EDS, isotherm nitrogen adsorption, SEM, HR-TEM, H2-TPR, CO2-TPD and Raman. Catalytic activity survey and analysis show the excellent performance of Ni/r-CeO2 with a Ni loading of 15 wt% (15NiCe) calcined at 600 °C for 4 h and reduced at 450 °C for 2.5 h. By adjusting the nickel loading on ceria and altering synthesis conditions, it's possible to achieve highly dispersed NiO particles with an optimal size (∼13.9 nm), abundant oxygen vacancies, and the presence of medium-strength basic sites. This leads to improved catalytic activity, resulting in an equilibrium CO2 conversion rate of approximately 90% and 100% selectivity for CH4 at temperatures as low as 325°C. The 15Ni/r-CeO2 catalyst serves as a highly active low-temperature catalyst for CO2 methanation.

期刊介绍: In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research. Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science. With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
