“…[7][8][9] To date, both heterogeneous and homogeneous catalysts have been widely used in the selective hydrogenation of LA to GVL. Heterogeneous catalysts, i.e., Ru-, [9][10][11][12][13][14] Pt-, 15 Fe-, 16 Co-, 17 Ni-, 18 and Cu-based catalysts, 16,19 exhibit good activity for LA hydrogenation. Compared with heterogeneous catalysts, homogeneous catalysts, including Ru-, [20][21][22][23][24] Ir-, [25][26][27] Pt-, 28 and Nicontaining complexes, 5,29 have higher catalytic efficiency and selectivity under mild reaction conditions.…”
