报告摘要：

Photon-driven small molecules activation, eg. H₂O splitting, is scientifically and industrially of significance as it promises an efficient pathway for green H₂ production. However it is kinetically very challenging due to a multi-electron process [1]. For green chemicals synthesis, other inert molecules activation (e.g. N₂, CO₂ and CH₄ etc) are equally important while rather challenging.

Our early study on charge dynamics in inorganic catalysts reveals that the current low solar to fuel/chemical conversion efficiency is due to both fast charge recombination and sluggish oxidation reaction [2], we thus developed effective material strategies to improve the activities of catalysts. Typically, we found that photon-phonon codriven process over single atom catalysts could dramatially improve H2 production [3]. Furthermore, this new process has been demonstrated duirng catalytic C1 conversion to C₂ [4] and C2 to C4 [5], both achieving the benchmark results in the related fields. Very recently, we developed a new concept of an intramolecular junction, which is composed of alternate benzene and triazine motifs in CTF polymer. Such structure can facilitate fast charge separation and is characterised by spatially separated reduction and oxidation sites in one molecular unit, thus substantially improving the methane conversion to ethanol and mitigating the overoxidation to CO₂, which together with photon-phonon co-driven catalysis results in an unprecedented ethanol yield and selectivity of 80% operated under mild condition [6].
