Activation of inert bond and molecule: （1）CO2 utilization for green synthesis （Nature Catalysis 2018, 1, 469; CCS Chem. 2021, 3, 1848). （2）C-H activation, inert bond/molecule activation (Angew. Chem. 2023, e202300905; Angew. Chem. 2019, 58, 18502; Nature Commun. 2016, 7, 10443). （3）Green synthetic methodology development: transition-metal catalysis, photocatalysis and more (J. Am. Chem. Soc. 2020, 142, 8122; CCS Chem. 2021, DOI: 10.31635/ccschem.021.202101156)
