AbstractDry reforming of methane (DRM) is an attractive route to utilize CO2 as a chemical feedstock with which to convert CH4 into valuable syngas and simultaneously mitigate both greenhouse gases. Ni-based DRM catalysts are promising due to their high activity and low cost, but suffer from poor stability due to coke formation which has hindered their commercialization. Herein, we report that atomically dispersed Ni single atoms, stabilized by interaction with Ce-doped hydroxyapatite, are highly active and coke-resistant catalytic sites for DRM. Experimental and computational studies reveal that isolated Ni atoms are intrinsically coke-resistant due to their unique ability to only activate the first C-H bond in CH4, thus avoiding methane deep decomposition into carbon. This discovery offers new opportunities to develop large-scale DRM processes using earth abundant catalysts.

Abstract Methane dry reforming reaction (DRM) can convert CO2 and CH4, two kinds of greenhouse gases with very stable chemical properties, to produce syngas, which can be used to synthesize valuable industrial products. Nickel-based catalysts have been widely used in DRM because of their low cost and good catalytic activity. However, nickel application is limited by such as high-temperature metal sintering, carbon deposition and catalyst poisoning, which restricts the industrial application in DRM reaction. Compared with single metal nickel, the selective doping of multi metals and supports shows higher catalytic activity and anti poisoning tolerance due to changing the chemical and structural properties of the catalyst by enhancing the alloy effect and the force between metal and support. This paper mainly reviews the catalysts with anti-coking, anti-sintering and anti-sulfur poisoning by tuning the metal-metal interaction and metal-support interaction (MSI) in DRM. The modification strategies in interfacial engineering and structure-performance relationship are discussed, and the existing difficulties and future development of Ni-based catalysts are proposed.
