 1. 报告题目：New Trends in CO2 Hydrogenation Catalysts

报告人：Kohsuke Mori（大阪大学教授）

报告摘要：

 The hydrogenation of CO2 to high calorific fuels has the potential to alleviate both climate change and future demands for fossil fuels. As an example, the hydrogenation of CO2 to formic acid (FA) in the liquid phase (CO2 (aq.) + H2 (aq.) → HCOOH (aq.), ΔG = −4 kJ mol−1 has attracted much attention, because FA has emerged as one of the most promising hydrogen storage compounds. On the other hand, the gas phase CO2 methanation reaction (CO2 + 4H2 → CH2 + 2H2O, ΔH = −165.0 kJ mol−1), also known as the Sabatier reaction, has attracted new interest because of the recent development of the power-to gas concept. This reaction is also recognized as an important approach to powering long-term space exploration missions. Because the activation of highly stable CO2 requires massive energy input, a reliable catalyst is desired to lower the activation energy and accelerate the conversion.

 Herein, I would like to introduce new design concepts in CO2 hydrogenation catalysts. Firstly, PdAg alloy nanoparticles supported on TiO2, which was made using surface engineering with atomic precision, was proven to be active for the hydrogenation of CO2 to give FA. Secondary, high entropy alloy (HEA) nanoparticle (NP) catalyst was synthesized at 400 °C by the assist of hydrogen spillover effect on TiO2 support via a coupled proton–electron transfer mechanism. The obtained CoNiCuRuPd/TiO2 catalyst exhibited different selectivity and significantly improved stability compared with Pd/TiO2 during the hydrogenation of CO2 Thirdly, a multifunctional self-catalytic reactor (SCR) was designed via metal 3D printing and selective electrochemical dissolution as a method to not only simplify the catalyst development process but also fabricate active catalysts for CO2 methanation.

 Kohsuke Mori has been a professor at the University of Osaka since 2025. He received his PhD degree from the Graduate School of Engineering Science at Osaka University under the supervision of Prof. K. Kaneda in 2003. In 2004, he joined Prof. T. Don, Tilley's group at University of California, Berkeley as a postdoctoral fellow. He moved to his current faculty in 2005 and then became an associate professor in 2009.  

 His current research interests focus on establishment of environmentally friendly carbon neutral hydrogen energy process based on unique alloy nanoparticle catalysts, catalytic reactors designed by metal 3D printing, and control & utilization of hydrogen spillover.

 Dr. Mori was awarded Physical Chemistry Chemical Physics Prize (2010), Catalysis Society of Japan, Young Scientist Award (2013), The Japan Institute of Metals and Materials, Meritorious Award (2017), and JACI Green Sustainable Chemistry, Minister of Education, Culture, Sports, Science and Technology Award (2023).

2. 报告题目：Unraveling Reaction Networks in Catalysis:From HCN Emissions to Selective Methanol Coupling

报告人：Abhishek Khetan（德国亚琛工业大学助理教授）

报告摘要：

 This talk presents two computational studies on copper-zeolite catalysts, one revealing the molecular mechanism of HCN formation during emission control and another exploring methanol coupling for sustainable fuel synthesis. Together, they demonstrate how data-driven simulations can bridge emission control and fuel production to enable rational catalyst design.
