Controlled Synthesis of Mesoporous Nitrogen-Doped Carbon Supported Ni-Mo Sulfides for Hydrodesulfurization of Dibenzenethiophene

Mesoporous nitrogen-doped carbon was synthesized in a controlled manner by a modified deep eutectic solvent method using silica nanoparticles as templates. Various amounts of urea and glucose, which contain hydrogen acceptor and hydrogen bond donor groups were heated and stirred to form homogeneous liquid precursors like deep eutectic solvents, and nitrogen element was uniformly dispersed on an atom scale. Ni-Mo sulfides supported on mesoporous carbon with varying N dopping exhibit excellent hydrodesulfurization (HDS) catalytic performance such as high conversion and good recycling stability in the HDS of dibenzenethiophene. Further investigation showed that a suitable N content in the carbon support enhance the HDS properties and the HDS conversion could reach up to 96%. Graphical
