Selective and Efficient Photocatalytic Conversion of CO₂ with Ultrathin Nanosheets

Prof. Doh Chang Lee’s group has developed a novel photocatalyst based on ultrathin CdS nanosheets for selective and efficient light-driven conversion of CO₂ into CO. Surface engineering at atomic precision on CdS nanosheets enabled spatial separation of the reductive active sites and the oxidative active sites to designated facets. The facet-resolved redox-active sites favored efficient charge separation in the CdS nanosheets under light, leading to two-orders-of-magnitude increase in conversion rate of CO₂-to-CO. ...read more

Accelerated Material Design Framework using Uncertainty-Quantified Hybrid Machine Learning/Density Functional Theory Approach

Prof. Yousung Jung’s group has developed a new accelerated high throughput screening (HTS) method using uncertainty-quantified machine learning (ML) and density functional theory (DFT) that was applied to explore the Mg-Mn-O chemical space for photoanode application. Notably, the proposed HTS scheme required only 1.5% of the target chemical space for further DFT calculations, accelerating the entire process by > 50 times for the same discovery compared to the brute-force DFT-HTS done previously. This means an improvement of the screening performance (discoverability) by more than a factor of 2 compared to the conventional ML-based HTS approach....read more

Development of Efficient Nickel Catalyst for Dry Reforming of Methane

The rise of atmospheric CO₂ concentration has resulted in serious environmental problems. Dry reforming of methane (DRM) has gained tremendous attention because carbon dioxide can be converted into more useful chemicals with methane, which is also one of the most important greenhouse gases. In DRM research, noble metal catalysts have been extensively studied, but their high cost is a major obstacle. Nickel, which is considered to be promising due to its high activity but affordable price, has shown severe coke formation leading to rapid deactivation of catalysts so far. However, our nickel catalysts show high activity with exceptional durability for 600 hours of reaction. We believe these catalysts can contribute to environment and industries....read more
