Xiao H, Dong J, Zhang Y, Cao X, Li Y, He D, Luo Y, Wang P, Wang H. Highly efficient Ni/Ac-Al 2O 3 catalysts in the dry reforming of methane: influence of acetic acid treatment and Ni loading. RSC Adv 2024; 14:39061-39068. [PMID: 39659601 PMCID: PMC11629874 DOI: 10.1039/d4ra06740a] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2024] [Accepted: 11/06/2024] [Indexed: 12/12/2024] Open
Abstract
The presence of abundant hydroxyl groups on the surface of Al2O3 can promote the dispersion of Ni species but produce an inactive NiAl2O4 phase at high temperatures. Moreover, the catalysts prepared by the conventional incipient wetness impregnation method lack the sites for the activation of CO2, which leads to coke deposition and thus affects the catalyst activity. The above restricts the utilization of Ni in conventional Ni/Al2O3 catalysts. In this paper, Al2O3 support was pre-treated by acetic acid to selectively remove hydroxyl groups without affecting the coordination environment of Al. Results revealed that the Al2O3 support after hydroxyl removal not only showed moderate metal-support interaction but also produced more sites for the adsorption and activation of the reactant, which significantly improves the utilization of nickel species and the stability of the catalyst. The conversion of CH4 and CO2 at 700 °C was as high as 88% and 90%, respectively, and has an excellent stability of 50 h. This study provides a feasible strategy for the design of highly active methane dry-reforming catalysts.

[PMID: 39073286 DOI: 10.1002/asia.202400700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2024] [Revised: 07/22/2024] [Accepted: 07/28/2024] [Indexed: 07/30/2024]
Abstract
Two-component catalysts have garnered significant attention in the field of catalysis due to their ability to inhibit Ni sintering. In the present work, honeycomb-structuralstructured Al2O3-supported Ni and B were prepared to enhance coke tolerance during dry reforming of methane (DRM). Transmission electron microscopy (TEM) results revealed that the average particle sizes on Ni/Al2O3 and Ni-0.16B/Al2O3 were 7.6 nm and 4.2 nm, respectively, indicating that B can effectively inhibit Ni sintering. After a 100-hour reaction, the conversion of CH4 and CO2 on Ni/Al2O3 decreased by approximately 5 %, whereas on Ni-0.16B/Al2O3, there was no significant decrease in CH4 and CO2 conversion, with values of approximately 81.6 % and 87.2 %, respectively. In situ DRIFT spectra demonstrated that Ni-0.16B/Al2O3 enhanced the activation of CO2, thus improving the catalyst's stability. A Langmuir-Hinshelwood-Hougen-Watson (LHHW) model was developed for intrinsic kinetics, and the resulting kinetic expressions were well-fitted fit to the experimental data, with R2 values exceeding 0.9. ActivationThe activation energies were also calculated. The outstanding stability of Ni-0.16B/Al2O3 can be attributed to its stable honeycomb structure and B's ability to significantly inhibit Ni sintering, reduce catalyst particle size, and enhance coke tolerance.

Abstract
Dry reforming of methane (DRM), the catalytic conversion of CH4 and CO2 into syngas (H2+CO), is an important process closely correlated to the environment and chemical industry. NiAl-based catalysts have been reported to exhibit excellent activity, low cost, and environmental friendliness. At the same time, the rapid deactivation caused by carbon deposition, Ni sintering, and phase transformation exerts great challenges for its large-scale applications. This review summarizes the recent advances in NiAl-based catalysts for DRM, particularly focusing on the strategies to construct efficient and stable NiAl-based catalysts. Firstly, the thermodynamics and elementary steps of DRM, including the activation of reactants and coke formation and elimination, are summarized. The roles of Al2O3 and its mixed oxides as the support, and the influences of the promoters employed in NiAl-based catalysts over the DRM performance, are then illustrated. Finally, the design of anti-coking and anti-sintering NiAl-based catalysts for DRM is suggested as feasible and promising by tailoring the structure and states of Ni and the modification of Al-based supports including small Ni size, high Ni dispersion, proper basicity, strong metal-support interaction (SMSI), active oxygen species as well as high phase stability.

Abstract
Methane dry reforming (MDR) has attracted significant attention for effectively consuming greenhouse gases and producing valuable syngas. The development of coking- and sintering-resistant catalysts is still a challenge. Herein, highly active Ni nanocatalysts confined by the active edges of boron nitride have been originally developed, and the coking- and sintering-resistant MDR mechanism has also been unraveled. The active edges of boron nitride consisted of boundary BOx species interact with Ni nanoparticles (NPs), which can contribute to the activation of both CH4 and CO2. The etching of BN is restrained under the buffer of boundary BOx species. Operando spectra reveal that the formation and conversion of active bicarbonate species is accelerated by the boundary BOx species. The complete decomposition of CH4 is suppressed, and thus the coke formation is restricted. The functional groups of active BN edges are confirmed to stabilize the Ni NPs and facilitate the MDR reaction. This work provides a novel approach for the development of coking- and sintering-resistant catalysts for MDR.

Abstract
Coking and metal sintering are limitations of large-scale applications of Ni/Al2O3 catalysts in DRM reactions. In this review, several modification strategies to enhance the anti-deactivation property of Ni/Al2O3 are proposed and discussed with the recently developed catalyst systems, including structure and morphology control, surface acidity/basicity, interfacial engineering and oxygen defects. In addition, the structure–performance relationship and deactivation/anti-deactivation mechanisms are illustrated in depth, followed by prospects for future work.
