“…Important and very recent results that confirm the role of iron on the dispersion of NiO nanoparticles, increasing the quantity of the reduced active nickel species, were reported by Lu et al regarding zirconia-supported doped nickel catalysts [255] and Pandey et al, regarding five series of Ni-Fe bimetallic supported catalysts [256]. The morphology of Ni-ZrO 2 and Ni-Fe/ZrO 2 catalysts has been compared.…”

Supported Catalysts for CO2 Methanation: A Review

et al. 2017

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.

“…The morphology of Ni-ZrO 2 and Ni-Fe/ZrO 2 catalysts has been compared. Using TEM images, it is possible to notice that the average size of NiO particles on the Ni-ZrO 2 catalyst is higher than the average size of the NiO particles dispersed on Ni-Fe/ZrO 2 catalyst [255].…”

The Synergy Effect of Ni-M (M = Mo, Fe, Co, Mn or Cr) Bicomponent Catalysts on Partial Methanation Coupling with Water Gas Shift under Low H2/CO Conditions

et al. 2017

Ni-M (M = Mo, Fe, Co, Mn or Cr) bicomponent catalysts were prepared through the co-impregnation method for upgrading low H 2 /CO ratio biomass gas into urban gas through partial methanation coupling with water gas shift (WGS). The catalysts were characterized by N 2 isothermal adsorption, X-ray diffraction (XRD), H 2 temperature programmed reduction (H 2 -TPR), H 2 temperature programmed desorption (H 2 -TPD), scanning electron microscopy (SEM) and thermogravimetry (TG). The catalytic performances demonstrated that Mn and Cr were superior to the other three elements due to the increased fraction of reducible NiO particles, promoted dispersion of Ni nanoparticles and enhanced H 2 chemisorption ability. The comparative study on Mn and Cr showed that Mn was more suitable due to its smaller carbon deposition rate and wider adaptability to various H 2 /CO and H 2 O/CO conditions, indicating its better synergy effect with Ni. A nearly 100 h, the lifetime test and start/stop cycle test further implied that 15Ni-3Mn was stable for industrial application.

“…While CO 2 methanation catalysts based on noble metals such as Rh or Ru do not normally present sintering problems, Ni, Cu or Co based samples, among others, are more susceptible to metal particles agglomeration and aggregation, leading to significant effects on the dispersion. In this context, several works reported the beneficial effect of adding transition metals, noble metals, lanthanides or even alkali earth metals in partially suppressing Ni particles sintering ,,,,,,,,. Among all, Ce has been the most commonly used,,,,,,,, mainly due to its effects, not only on the dispersion of the metallic species (from ∼19 to ∼3 nm Ni 0 particles in 5 %Ni/USY and 5 %Ni‐3 %Ce/USY catalysts, respectively), but also due to the favoured activation of CO 2 over Ce species, as it will be further discussed later.…”

The incorporation of La over 10 wt.% Ni/BEA was also found to lead to a decrease in the metallic Ni particles size from 20 in the Ni/BEA catalyst to~12,~9 and~7 nm in the bimetallic samples containing 10 wt.% Ni and 5, 10 and 15 wt.% La.…”

Tuning Zeolite Properties towards CO₂ Methanation: An Overview

This work provides a short review of the literature concerning the utilization of zeolites as supports for CO2 methanation catalysts. Indeed, the application of these materials in carbon dioxide hydrogenation into methane has led to considerably relevant performances according to the literature, being zeolite‐based catalysts more active and selective than commercial materials reported. Considering the well‐known zeolite features and the possibility to finely modulate its properties, inducing relevant changes on the adsorbed metal species and in the CO2 activation ability of the catalyst, potentially interesting catalytic properties can be generated also towards this transformation. Possible correlations between the characteristics of these materials, found as relevant for CO2 methanation, and the catalytic properties will be then presented and discussed.
