Catalyst deactivation is mainly caused by catalyst sintering, and causes billions of dollars of extra expenditure on catalyst regeneration. Gaining insights into the sintering kinetics and mechanisms ...
Tracking the shape-dependent sintering of platinum–rhodium model catalysts under operando conditions
Nanoparticle sintering during catalytic reactions is a major cause for catalyst deactivation. Understanding its atomic-scale processes and finding strategies to reduce it is of paramount scientific ...
WHOEVER SAID, "It's difficult to make predictions, especially about the future," probably wasn't referring to Fischer-Tropsch (FT) chemistry. But the adage is apt just the same. The economics of ...
In the study, which was published July 15 in the ACS journal Nano Letters, the researchers described a possible new way to solve one of the key causes of degradation of platinum catalysts, sintering, ...

For the first time, researchers have created a nanocomposite of ceramics and a two-dimensional material, opening the door for new designs of nanocomposites with such applications as solid-state ...
Researchers reveal why trace amounts of alloy added to some catalysts keep them performing better over time. The study suggests models that could boost manufacturing. A team of researchers, including ...
BUFFALO, N.Y. – A byproduct of landfilling, livestock farming, coal mining and other human activities, methane emissions are one of the key drivers of climate change. Yet for decades scientists have ...
• A novel platinum-alumina catalyst that allows removal by oxidation of harmful volatile organic compounds present in factory exhaust gases has been developed. • The reaction temperature is 100 ºC ...
