Carbon-supported intermetallic nickel silicide (Ni₂Si/C) as a non-sulfide catalyst derived from Ni-MOF-74 presents high activity and sulphur-resistance in the hydrodesulfurization (HDS) of dibenzothiophene (DBT). The Ni₂Si/C catalyst possesses a large specific surface area (168 m² g⁻¹), small crystallite size (12 nm) and high electronic density of the nickel active sites; thus, they demonstrate HDS properties breaking the metal silicide bottleneck derived from the microelectronic industry during catalysis. Due to the strong electron-donating effect between Ni and Si and the modification effect by a porous carbon matrix, the Ni₂Si/C catalyst exhibits an outstanding stability during DBT HDS after 120 h of stability testing.

基于MOF的路线提高耐硫金属间化合物Ni2Si的加氢脱硫性能

由Ni-MOF-74衍生的碳载金属间金属硅化镍（Ni ₂ Si / C）作为非硫化物催化剂在二苯并噻吩（DBT）的加氢脱硫（HDS）中表现出高活性和抗硫性。Ni ₂ Si / C催化剂具有比表面积大（168m ² g ^-1），微晶尺寸小（12nm）和镍活性部位的高电子密度。因此，他们证明了HDS性能打破了催化过程中源自微电子工业的金属硅化物瓶颈。由于Ni和Si之间的强电子给体作用以及多孔碳基质对Ni ₂的改性作用Si / C催化剂在120小时的稳定性测试后显示出出色的DBT HDS稳定性。
