A Review on the Water‐Gas Shift Reaction over Nickel‐Based Catalysts

et al. 2022

View full text Add to dashboard Cite

Recent advances in supported nickel catalysts for the water-gas shift (WGS) reaction are reviewed, focusing on the structuremechanism relationships. The WGS reaction can proceed via the redox, carboxyl, and formate pathways over the supported nickel catalysts. However, a discrepancy exists between the mechanism-level understanding and catalyst design principles in literature. In this review, we summarized the mechanismstructure relationship of nickel-based catalysts, emphasizing the effects of the formation of alloy, modification of the support or addition of alkali metal promoters on the CO adsorption and the H 2 O dissociation in the process of WGS reaction. Future research is suggested to systematically investigate the reaction mechanism & kinetics for different catalyst structures. In addition, the manipulation of strong metal-support interactions and the development of new types of supports are prospective directions.

“…A reverse water–gas shift-chemical looping (RWGS-CL) process − can facilitate oxygen release from oxides, allowing milder operation conditions than those of the solar thermochemical CO 2 reduction process. RWGS-CL also has a two-step cycle based on a chemical looping concept, as depicted in Figure . Since the oxides are reduced under a H 2 atmosphere at a much lower temperature than that required for thermochemical CO 2 splitting, the overall operation temperature of RWGS-CL can also be lowered.…”

Fundamental Aspects of Enhancing Low-Temperature CO₂ Splitting to CO on a Double La₂NiFeO₆ Perovskite

This paper addresses the synergistic effect of binary Ni–Fe sites in double La2NiFeO6 perovskite on low-temperature CO2 conversion to CO in the reverse water–gas shift-chemical looping process. Experimental investigations and DFT calculations proved that, for the reduction of perovskite, the Ni-site facilitates the formation of surface oxygen vacancies and the adsorption of hydrogen with agile lattice oxygen mobility. Thus, incorporating Ni can improve the reducibility at low temperature. The Fe-site prevents strong adsorption of the CO2 molecules on the La-site to facilitate its direct dissociation into CO molecules, and thereby CO2 conversion increases with Fe loading. Consequently, La2NiFeO6 can satisfy both high reducibility and CO2 splitting activity by the synergy of binary Ni–Fe sites. It presents an average CO productivity of 2.14 mmol/gcat and a maximum CO production rate of 1.69 mmol/gcat·min at 700 °C, more than 4.7-fold and 10-fold higher than each single LaNiO3 and LaFeO3 perovskites, respectively.

“…Among many types of stoichiometric metal oxides, Fe based metal oxides were actively investigated as redox materials because Fe shows good reactivity toward water splitting. As the introduction of heterogeneous metal species can alter the thermodynamic properties of oxide and overcome the thermodynamic limitation of Fe 2 O 3 , , incorporation of catalytically active Ni makes Ni-ferrite (NiFe 2 O 4 ) a promising redox material for H 2 production. Nevertheless, deterioration of H 2 productivity during redox cycling is considered as a major problem in the stoichiometric materials.…”

Although chemical looping technology has enabled energy-efficient H2 production by combining separation and reaction through the lattice oxygen in oxygen storage materials (OSMs), metal oxides undergoing successive reduction–oxidation cycles generally suffer from a decline in long-term performance. This work investigates an Al-incorporated Ni-ferrite (NiFe2O4) particle to demonstrate a detailed deactivation mechanism induced by redox stress and suggests a strategy to prolong the lifespan of the particle. It is revealed that the grain coalescence and surface densification hamper the redox performance by decreased electrical conductivity and retarded gas transfer, eventually leading to deactivation over the cycles. The formation of a spinel solid solution with aluminum (Al) incorporation was found to be an effective strategy to prevent densification and maintain the long-term performance. Al incorporation at 3.3 wt % is determined as the best particle that can maintain the highest H2 yield (8.2 mmol H2·g–1) and average production rate (0.41 mmol H2·g–1·min–1) for 11 cycles.
