“…On the other hand, the catalyst may also deactivate if severe SMSI‐induced encapsulation happens. As a result, it is important to develop efficient strategies to regulate (either promote or inhibit) the SMSI effect for nickel‐based catalysts [152–154] The support and dopants may facilitate several elementary steps of the WGS reaction and, consequently, improve the catalyst‘s performance.…”

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.

“…As an important component of the catalyst, the influence of the support on the activity and stability of the catalyst cannot be ignored. Catalyst supports can affect the dispersion and size of active metals and can also enhance catalyst activity and stability by interacting with active metals [104]. The various catalyst supports proposed in the Section 3.2 (such as ZnO, SiO 2 , Al 2 O 3 , and CeO 2 ) play different roles.…”

The advent of fuel cells has led to a series of studies on hydrogen production. As an excellent hydrogen carrier, methanol can be used for reforming to produce hydrogen. Copper-based catalysts have been widely used in methanol reforming due to their high catalytic activity and low-cost preparation. However, copper-based catalysts have been subjected to poor stability due to spontaneous combustion, sintering, and deactivation. Thus, the research on the optimization of copper-based catalysts is of great significance. This review analyzes several major factors that affect the stability of copper-based catalysts, and then comments on the progress made in recent years to improve the catalytic stability through various methods, such as developing preparation methods, adding promoters, and optimizing supports. A large number of studies have shown that sintering and carbon deposition are the main reasons for the deactivation of copper-based catalysts. It was found that the catalysts prepared by the modified impregnation method exhibit higher catalytic activity and stability. For the promoters and supports, it was also found that the doping of metal oxides such as MgO and bimetallic oxides such as CeO2-ZrO2 as the support could present better catalytic performance for the methanol reforming reaction. It is of great significance to discover some new materials, such as copper-based spinel oxide, with a sustained-release catalytic mechanism for enhancing the stability of Cu-based catalysts. However, the interaction mechanism between the metal and the support is not fully understood, and the research of some new material copper-based catalysts in methanol reforming has not been fully studied. These are the problems to be solved in the future.

“…11 Recent studies have shown that Cu nanoparticles exhibit plasmon resonance absorbance in the visible as well as in the infrared region, which implies that Cu nanoparticles have the prospect of replacing precious metals for photocatalysis and enhanced NIR absorption in the future. 12,13 However, the presence of Cu in many systems containing Cu/TiO 2 is mainly in the form of CuO and Cu 2 O, [14][15][16][17][18] and fewer Cu nanoparticles/TiO 2 systems have been studied. And most of the Cu nanoparticles/TiO 2 systems are studied for photocatalytic activity.…”
