Hydrodesulfurisation (HDS) is the industrial process for catalytic sulphur removal from sulphur-containing molecules in refineries' crude oil fractions. A novel route to an efficient bulk HDS catalyst is reported. It uses a MOF (metal organic framework) as a sacrificial template. The catalytic final Ni-doped MoS2 nanocrystals (see HRTEM ), obtained by sulfidation after well-controlled large scale post-synthesis modification of the MOF Ni2(dhtp), are twice as active with respect to benchmark unsupported catalyst while containing fourfold less molybdenum.

Use of MOF Ni2(dhtp) (H4dhtp = 2,5-dihydroxyterephtalic acid) as sacrificial template for synthesis of 3-layer Ni-doped MoS2 as bulk HDS catalyst
