Pilot-scale investigation of mass transfer and performance of NO 2 absorption in alkaline scrubbing systems

This study addresses the critical challenge of NO2 mass transfer efficiency in wet denitration systems through a pilot-scale investigation of oxidation-alkali-coupled absorption. Utilizing dual Φ600 mm packed towers equipped with polypropylene 350Y structured packing, the perform...

Tuning electron back-donation to switch reaction pathway in CO2 hydrogenation

CO2 hydrogenation over earth-abundant Ni catalysts is attractive for CO-based fuel synthesis, but Ni intrinsically favors methanation. Here we show that ordered Ni3Sn2 intermetallics tune Ni–CO electron back-donation and switch CO2 hydrogenation from CH4 formation to the reverse...

What is happening at the atomic level during the seed-mediated growth of copper on gold?

Bimetallic nanocrystals obtained via seed-mediated growth are typically analyzed using conventional electron microscopy and many interesting features at the atomic level are often missed. Here we report the seed-mediated growth of copper (Cu) on gold (Au) nanospheres for the synt...
