Carbon dioxide electroreduction (CO2 RR) is a sustainable way of producing carbon-neutral fuels. Product selectivity in CO2 RR regulated by the adsorption energy reaction-intermediates. Here, we employ differential phase contrast-scanning transmission electron microscopy (DPC-STEM) to demonstrate that Sn heteroatoms on Ag catalyst generate very strong and atomically localized electric fields. In situ attenuated total reflection infrared spectroscopy (ATR-IR) results verified field enhances...
While the role of crystal facets is well known in traditional heterogeneous catalysis, this effect has not yet been thoroughly studied plasmon-assisted where attention primarily focused on plasmon-derived mechanisms. Here, we investigate electrocatalytic CO
Plasmons have facilitated diverse analytical applications due to the boosting signal detectability by hot spots. In practical applications, it is crucial fabricate straightforward, large-scale, and reproducible plasmonic substrates. Dewetting treatment, via applying direct thermal annealing of metal films, has been used as a straightforward method in fabrication such nanostructures. However, tailoring evolution dewetting process films poses considerable experimental complexities, mainly...

In the realm of plasmonic catalytic systems, much attention has been devoted to plasmon-derived mechanisms, yet influence nanoparticles' crystal facets in this type processes sparsely investigated. work, we study plasmon-assisted electrocatalytic CO2 reduction reaction using three different shapes Au nanoparticles - nanocube (NC), rhombic dodecahedron (RD) and octahedron (OC) with exposed facets: {100}, {110} {111}, respectively. These particles were synthesized similar sizes LSPR...
