報告內容摘要：
As underlined in the COP26, methane as a greenhouse gas is nearly 25 time more potent than CO2while its reserve is much more than the sum of coal, oil and natural gas. Thus methane conversion not only involves the environmental issue but more importantly is regarded as the most promising pathway for high-value chemical synthesis. However CH4activation is energy intensive and kinetically very sluggish so that methane activation is regarded as the “holy grail” in the catalytically chemical process [1]. Photocatalysis provides a cost-efficient potential to activation of such small molecule under very mild conditions, while to achieve the potential is a huge challenge [2].
Stimulated by our research outcomes on the charge dynamics, which reveal that the low reaction efficiency is due to fast charge recombination and large bandgap of a semiconductor [3], we developed novel material strategies for photocatalytic methane conversion. Highly dispersed atomic level iron on TiO2shows an excellent activity for methane conversion, resulting into ~97% selectivity towards alcohols operated under ambient conditions by a one-step chemicalprocess [4].The dominating function of the iron species has also been investigated in detail. C1 oxygenates can also be produced with nearly 100% selectivity by oxide photocatalyts due to the synergy between Au and Cu cocatalysts loaded on ZnO [5]. Furthermore, we coupled photons with phonons to co-drive catalytic methane conversion to C2 over Au loaded TiO2, achieving the benchmark results in this area [6]. Finally for the first time, we demonstrated the photon-phonon co-driven catalysis for methane to formaldehyde with a nearly 90% selectivity [7].
