Highly dispersed Ni/Al2O3 catalysts for dry reforming of methane prepared by alkaline-induced adsorption process

Ni–Al catalysts were widely developed for methane dry reforming (DRM) and other valuable reactions, but the low utilization of Ni species on Al2O3 support has limited its further application. In this paper, induced to anchor mesoporous under alkaline conditions. Notably, treatment caused corrosion restructure Al2O3, reorganization process presence defects from ligand-unsaturated Al3+ (Alpenta3+) promoted remain uniform dispersion surface. combination with TEM, HRTEM, UV–vis H2 chemisorption, it is observed that formed a special layered stacking structure conditions, which contributed homogeneous distribution catalyst Surprisingly, showed good low-temperature DRM reactivity, was superior conventional prepared by impregnation method most reported in literatures. The CH4 rate RCH4-mNi = 80.16 (L/h/g) at 550 °C obtained catalyst, while adsorption significant increase RCH4−mNi 160.87 (L/h/g). Consequently, present work provides some ideas synthesis efficient as well meaningful reactions.
