PNNL Advances Science to Convert Plastics to Fuels
PNNL scientists discovered a promising approach to make it easier to turn petroleum-based plastic waste into chemicals that can be used to produce new materials and fuels. Read more.
Less Platinum, Faster Chemical Reactions
A new study in the journal Nature from a multi-institutional research team reported a discovery that simultaneously reduces the need for rare and expensive platinum and speeds up important chemical reactions. The research team solved a long-standing problem: when metal atoms are exposed to the conditions required for chemical reactions, they tend to clump together. Read more.
the Effects of Molybdenum Doping on CO2 Conversion
Understanding how to create and control catalysts that can turn CO2 into useful products is essential for closing the carbon cycle. Recent research provides an approach for catalyst modification that can be used to create more efficient and more selective catalysts for CO2 conversion. Read more.
Controlling Hydrogenation through Molecular Structure and Electric Potential
A new study looked at the electrocatalysis of carbonyls on palladium. Through a combination of spectroscopy, electrochemical characterization, and reaction kinetics, researchers found that small amounts of excess electrical energy favor hydrogenation. Read more.
Deep Learning to Understand Heterogeneous Catalysts
Heterogeneous catalysts have complex surface and bulk structures, and often sparse distribution of catalytic particles with relatively poor intrinsic contrast, which possess a unique challenge for image segmentation. To tackle this problem, researchers applied a deep learning-based approach for the multi-class semantic segmentation of a γ-Alumina/Pt catalytic material in a class imbalance situation. This work demonstrates how machine learning can be integrated into tomography to streamline analysis. Read more.
Isolation and Characterization of a Rationally Designed Copper Hydride Monomer
This study shows the impact of the synergy and close collaboration in the Institute for Integrated Catalysis between synthetic chemists, kineticists, and X-ray crystallographers to address the longstanding proposal of a fleeting monomeric copper hydride intermediate in molecular CuH catalysis.
