“…Meanwhile, the apparent activation energy ( E a ) without significant difference (Figure S8) suggests that Ni/MCM‐41 samples show similar reaction pathway for CO 2 reduction. It should be emphasized that the exceptional activity of Ni/MCM‐41‐NH 3 ⋅ H 2 O catalyst for CO 2 methanation is close to the equilibrium value and is higher than that of the previously reported Ni‐based catalysts on the indicated conditions, especially under the high GHSV (Table S3) ,. Furthermore, the low activity (48.1 % of CO 2 conversion) obtained for the reference sample of NaOH‐treated Ni/MCM‐41‐NH 3 ⋅ H 2 O confirms the negative effect of Na on Ni 0 generation and the cooperative catalysis of Ni and NiO species.…”

The use of CO2 to produce value‐added energy chemicals is a promising means for renewable CO2 transformation in low‐carbon energy system, and CO2 methanation has attracted ever‐increasing interest. Herein, we report that the Ni/MCM‐41 catalyst with prominent cooperative effect of Ni and NiO is efficient for CH4 generation with CO2 conversion of 73.2 % and CH4 selectivity of 91.6 % at 400 °C and high gas hourly space velocity (GHSV) of 90000 mL gcat−1 h−1. Combined methodologies of in situ X‐ray diffraction, diffuse reflectance infrared Fourier transform spectroscopy, and ambient‐pressure X‐ray photoelectron spectroscopy reflect the structural evolvements of Ni/MCM‐41 catalyst, the presence of carbonyl intermediates, the co‐existence of metallic and oxidized Ni species with sufficient molar ratio of Ni0/Ni2+ under working conditions. H2 and CO2 molecules are preferentially adsorbed and chemically activated over Ni0 and Ni2+ species, respectively. The possible four‐step reaction mechanism involved carbonyl pathway and the cleavage of C=O bond from CO2 as the rate‐determining step over the engineered Ni/MCM‐41 catalyst was demonstrated.

“…Supported Ni catalysts are the most widely investigated materials for CO 2 methanation due to their high efficiency in CH 4 production and low cost [75][76][77][78][79][80][81][82][83][84][85][86][87][88][89]. A lot of supports have been investigated for Ni catalysts since, as is well known, the catalytic performance strongly depends upon the nature and properties of the support.…”

Supported Catalysts for CO2 Methanation: A Review

et al. 2017

View full text Add to dashboard Cite

CO 2 methanation is a well-known reaction that is of interest as a capture and storage (CCS) process and as a renewable energy storage system based on a power-to-gas conversion process by substitute or synthetic natural gas (SNG) production. Integrating water electrolysis and CO 2 methanation is a highly effective way to store energy produced by renewables sources. The conversion of electricity into methane takes place via two steps: hydrogen is produced by electrolysis and converted to methane by CO 2 methanation. The effectiveness and efficiency of power-to-gas plants strongly depend on the CO 2 methanation process. For this reason, research on CO 2 methanation has intensified over the last 10 years. The rise of active, selective, and stable catalysts is the core of the CO 2 methanation process. Novel, heterogeneous catalysts have been tested and tuned such that the CO 2 methanation process increases their productivity. The present work aims to give a critical overview of CO 2 methanation catalyst production and research carried out in the last 50 years. The fundamentals of reaction mechanism, catalyst deactivation, and catalyst promoters, as well as a discussion of current and future developments in CO 2 methanation, are also included.

Policies and Motivations for the CO2 Valorization through the Sabatier Reaction Using Structured Catalysts. A Review of the Most Recent Advances

The current scenario where the effects of global warming are more and more evident, has motivated different initiatives for facing this, such as the creation of global policies with a clear environmental guideline. Within these policies, the control of Greenhouse Gase (GHG) emissions has been defined as mandatory, but for carrying out this, a smart strategy is proposed. This is the application of a circular economy model, which seeks to minimize the generation of waste and maximize the efficient use of resources. From this point of view, CO2 recycling is an alternative to reduce emissions to the atmosphere, and we need to look for new business models which valorization this compound which now must be considered as a renewable carbon source. This has renewed the interest in known processes for the chemical transformation of CO2 but that have not been applied at industrial level because they do not offer evident profitability. For example, the methane produced in the Sabatier reaction has a great potential for application, but this depends on the existence of a sustainable supply of hydrogen and a greater efficiency during the process that allows maximizing energy efficiency and thermal control to maximize the methane yield. Regarding energy efficiency and thermal control of the process, the use of structured reactors is an appropriate strategy. The evolution of new technologies, such as 3D printing, and the consolidation of knowledge in the structing of catalysts has enabled the use of these reactors to develop a wide range of possibilities in the field. In this sense, the present review presents a brief description of the main policies that have motivated the transition to a circular economy model and within this, to CO2 recycling. This allows understanding, why efforts are being focused on the development of different reactions for CO2 valorization. Special attention to the case of the Sabatier reaction and in the application of structured reactors for such process is paid.
