Abstract A strategy is introduced for producing highly dispersed Ni 2 P/functionalized CMK-3 hydrodesulfurization catalysts via the anchoring effect of high-temperature stable groups activated by ammonia. In the proposed method, HNO 3 acts as an oxidant that enables original CMK-3 to create more lactones and phenolic hydroxyls than acidified ammonium persulphate; these groups are activated with negative charges via the NH 3 effect, and thereby [Ni(NH 3 ) 6 ] 2 + ions can be anchored to the electronegative surface of functionalized CMK-3 via electrostatic adsorption. As a result, NiO and phosphatized Ni 2 P nanoparticles are highly dispersed on the HNO 3 -oxidized CMK-3 support, endowing the catalyst with excellent activity for 4,6-dimethyldibenzothiophene hydrodesulfurization.
