Liquid gallium is employed as a reaction medium to synthesize uniquely structured solid–liquid–solid core–shell–shell nanoparticles, enabling the fabrication of diverse metallic nanostructures with ex...

Using a combination of spectromicroscopy at BESSY II and microscopic analyses at DESY's NanoLab, a team has gained new insights into the chemical behavior of nanocatalysts during catalysis.

For researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign, a new avenue for reducing carbon emissions can be found on the side.

Encapsulation of a red-to-blue upconversion pair into polymer nanoparticles gives water-stable heterogeneous nanocatalysts with distinguished stability. Red light irradiation of these nanocatalysts i...

For the first time, researchers have discovered that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether a solid oxide cell is generating electricity or producing hydrogen. This finding introduces a new design principle for improving the performance of next-generation solid oxide cells.

Silver nanocatalysts have been found to switch where they perform their most important reactions depending on whether a solid oxide cell is making electricity or hydrogen. The discovery could enable s...

The growing global demand for clean energy and rising concerns over climate change have intensified the search for sustainable alternatives.

Manganese-based metal–organic frameworks (MOFs) metalated with Rh were used as pre-catalysts for CO2 hydrogenation. Activated in situ (80 % H2, 20 % CO2, 350°C), the resulting templated catalysts disp...

High-entropy nanoparticles (HENPs) hold great promise for electrocatalysis, yet optimizing their compositions remains challenging. This study employs active learning and Bayesian Optimization to acce...

Researchers from Skoltech have uncovered physical principles governing the remote "tuning" of nanocatalysts, where the ultra-thin platinum layer's properties can be controlled exclusively by modifying its metallic core's composition and structure.
