제목 Roles of Al promoter on mesoporous Rh-mpg-C3N4 for a liquid-phase carbonylation of methanol
초록  The positive roles Al promoter on the heterogeneous Rh-incorporated mesoporous graphitic carbon nitride (Rh-mpg-C3N4) were investigated for a liquid-phase carbonylation of methanol to acetic acid (AA) to compete with commercialized Rh-based homogeneous catalysts under the reaction conditions of 463K and CO pressure of 4.0 MPa for reaction duration of 1h. The Al-modified Rh-mpg-C3N4 at its optimal amount below 2.5 wt% showed a higher AA yield above 60% compared to the unmodified Rh-mpg-C3N4. A highly dispersed Lewis acidic Al species on the Rh-mpg-C3N4 increased the reverse esterification reaction rate of methyl acetate (MA) intermediate to AA, which has been known to be more favorable reaction on acidic sites through hydrolysis reaction of AA.
