DOI: 10.1016/j.fuel.2021.121995
Abstract: Abstract A Mn-modified ZSM-5 zeolite (Mn-HZ) was synthesized using a quasi-solid-phase method, and its physicochemical properties were characterized. The presence of tetracoordinated framework Mn(III) was confirmed using ultraviolet–visible and Raman spectroscopy measurements, X-ray photoelectron spectroscopy,… read more here.
