“…Molybdenum disulfide (MoS 2 ) has been widely used as a high-efficiency catalyst for hydrodesulfurization and hydrodeoxygenation of petroleum, biomass, and coal-derived liquids. ,, The catalytic sites of MoS 2 are generally considered to be unsaturated coordination sites at the edges. , When these unsaturated coordination sites are further promoted by Co or Ni atoms, MoS 2 -based catalysts can activate reactants more efficiently. − For the hydrogenation of substituted nitrobenzene, it has been reported that MoS 2 -based catalysts could efficiently catalyze the reduction of nitro compounds by using ammonia borane, hydrazine monohydrate, and NaBH 4 , as the reducing agents. For example, Guardia et al reported that single-layered chemically exfoliated MoS 2 nanosheets exhibited superior catalytic performance for the selective hydrogenation of nitro compounds using NaBH 4 as the hydrogen source.…”
