Highly dispersible cerium-oxide modified Ni/SBA-15 for steam reforming of bio-mass based JP10
Ni/SBA-15 modified by highly dispersed cerium-oxide was prepared with the aid of sucrose for steam reforming of JP10 (C 10 H 16 ). Their characterization showed that addition of appropriate amount ceria led to the formation of highly dispersed CeO 2 and Ni, and the CeO 2 covered smaller nickel particles like strawberry seeds to form much more interface between them. Their catalytic activity exhibited higher stability over time on stream of 6.5 h with conversion higher than 95% and higher carbon resistance (mass loss less than 4.5% by TG), which may derive from good properties below: (1) much more interface enhanced cooperation effect and increased turnover frequency at the interface; (2) the stronger interaction between Ni and ceria to suppress sintering by formation of Ni-O-Ce solid solution; (3) the large amount of oxygen vacancies from the formation of Ni-O-Ce solid solution and highly dispersed CeO 2 to facilitate the water–gas–shift reaction and carbon removal.
