Metal-introduced NiCuAl-LDH using chelating agent for steam reforming of methanol

In this study, we focus on NiCuAl-LDH and introduce various metal ion species (Ga, Ni, Fe, Nd, Zn, Mg, and Cu) using a chelating agent into calcined NiCuAl-LDH. We obtained a maximum methanol conversion of 82.6% and H2 yield of 53.5%. In addition, we found that the metal surface area of Ni and Cu increased compared to NiCuAl-LDH. On the other hand, results demonstrated that the presence of Ni(OH)2 and Cu(OH)2 on the catalyst surface had a positive effect on the MSR. We also tested the catalytic stability, introducing Cu by EDTA into calcined NiCuAl-LDH. & COPY; 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
