A strategy of KIT-6-carrier modification towards enhancement of desulfurization properties of mesoporous Zn-based sorbents for H2S removal from hot coal gas

•Ti/W doped KIT-6 for sorbents was synthesized via one-pot synthesis method.•Doping of Ti and W show different effects on porosity of carriers.•The dispersion of ZnO can be improved by using doped KIT-6 as carrier.•The modification of carriers results in better H2S removal property.•Sorbents with Ti doped carriers exhibits higher sulfidation/regeneration stability.
