In this study, a Ni/NiAl2O4/Al2O3 structured reforming catalyst is designed, and the impact of various preparation and reduction temperatures on the catalyst is investigated. The testing results revealed that the catalyst calcined at 1000 °C exhibited optimal catalytic activity when reduced at 600 °C while demonstrating exceptional resistance to carbon deposition at a reduction temperature of 750 °C. Additionally, compared to supported catalysts calcined at lower temperatures, spinel catalysts exhibit significantly enhanced stability and can operate stably for 200 h under the conditions of 10 mL/g·h, S/C = 2.5, and 750 °C, showing no signs of deactivation. The catalyst was characterized through combined XRD and SEM analysis, revealing that the enhancement in catalytic activity and  \nresistance to carbon deposition is primarily attributed to the defective spinel structure and the smaller Ni particles. Meanwhile, the stability is related to the strong metal−support interaction facilitated by the spinel structure, which provides valuable insights and directions for the design of highly stable catalysts.  \n1. INTRODUCTION  \nThe current society’s heavy reliance on fossil fuels and the energy utilization method based on internal combustion engines have significantly increased pollutant and CO2 emissions, exacerbating air pollution and the greenhouse effect in recent years. In response to these issues, various countries have proposed corresponding emission reduction plans.1 Solid oxide fuel cells (SOFCs) represent a promising approach for energy utilization, as they directly convert chemical energy into electrical energy through electrochemical reactions, offering higher theoretical efficiency.2 However, the current development of SOFCs is constrained by the inadequate infrastructure for hydrogen, which is primarily used as the fuel of SOFCs.3 Steam reforming (SR) can convert common liquid fuels such as diesel or gasoline into gaseous fuels rich in hydrogen, which can then be utilized in SOFCs.4,5 Furthermore, due to their high operating temperatures, SOFCs can also utilize fuels such as CO and CH4 present in the reformate gas. Additionally, the waste heat generated by SOFCs can provide heat for thereforming process, enabling more efficient energy utilization.6 However, the development of highly efficient reforming catalysts plays a pivotal role before the widespread application of SR-SOFC.  \nSupported oxides are the most commonly used catalysts in steam reforming for hydrogen production, where highly dispersed and nanosized metal particles can be achieved by loading active metals onto metal supports with high specific surface areas. Transition metals such as Ni and Co, as well as precious metals like Pt, Rh, and Ru, are commonly used as active metals.7−9 Compared to precious metals, transition metals Ni and Co are abundant, widely sourced, and low-cost, particularly Ni, which exhibits catalytic activity comparable to that of precious metals at the nanoscale, making it have a high potential as an active metal material.  \nAl2O3 is a porous support material that is frequently employed, with a specific surface area typically exceeding 150 m2/g. It also exhibits high sintering resistance, maintaining a high spec","cbCaigWAFPrJnTGA","https://ap.wps.com/l/cbCaigWAFPrJnTGA","pdf",5929442,"English","# Abstract\n# Introduction\n## Background: Fossil fuel emissions and SOFC need for hydrogen\n## Steam reforming and SR-SOFC integration\n## Catalysts for steam reforming and role of Ni/Al2O3\n## Challenges: metal sintering and carbon deposition","[{\"question\":\"How does the study optimize the catalyst preparation and reduction conditions?\",\"answer\":\"The work compares catalysts prepared and reduced at different temperatures.
