六、内容简介:

  Methane as a greenhouse gas is nearly 25 time more potent than CO2 while its reserve is much more than the sum of coal, oil and natural gas. However CH4 activation is energy intensive and kinetically very sluggish so that methane activation is regarded as the “holy grail” in the catalytically chemical process. 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.We developed novel material strategies for photocatalytic methane conversion. Highly dispersed atomic level iron on TiO2 shows an excellent activity for methane conversion, resulting into ~97% selectivity towards alcohols operated under ambient conditions by a one-step chemical process. 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. 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. Finally for the first time, we demonstrated the photon-phonon co-driven catalysis for methane to formaldehyde with a nearly 90% selectivity.

七、主讲人简介:

Prof. Junwang (John) Tang(唐军旺) is a Member of the Academy of Europe, a Royal Society Leverhulme Trust Senior Research Fellow, Fellow of the European Academy of Sciences, Fellow of the Royal Society of Chemistry, Fellow of IMMM and Honorary Fellow of CCS. He is the Founding Director of Industrial Catalysis Center in the Department of Chemical Engineering and Chair Professor of Materials Chemistry and Catalysis at Tsinghua University, China and an Adjunct Professor at University College London, UK.Tang’s research interests encompass coupling phonons with photons for small molecule activation to produce zero-carbon fuels and valuable chemicals as well as microwave catalysis, together with the investigation of the underlying charge dynamics and kinetics by state-of-the-art spectroscopies, resulting in >250 papers published in Nature Catalysis, Nature Energy, Nature Materials, Nature Sustainability etc. with ~30,000 citations. Prof. Tang has received many awards, including the 2022 IChemE Oil and Gas Global Awards, 2021 IChemE Andrew Medal, RSC Corday-Morgan Prize and Royal Society-Leverhulme Trust Senior Research Fellowship. He also sits on the Editorial Board of 5 international journals, eg. the Editor of Applied Catalysis B and Associate Editor of Chin. Journal of Catalysis etc.
