TL;DR: A highly active and durable class of electrocatalysts is synthesized by exploiting the structural evolution of platinum-nickel (Pt-Ni) bimetallic nanocrystals by exploitingThe starting material, crystalline PtNi3 polyhedra, transforms in solution by interior erosion into Pt3Ni nanoframes with surfaces that offer three-dimensional molecular accessibility.

TL;DR: A facile ligand-exchange approach is reported, which enables sequential surface functionalization and phase transfer of colloidal NCs while preserving the NC size and shape and represents an important step toward controllably engineering the surface properties of NCs.

TL;DR: An improved synthesis of colloidal gold nanorods (NRs) is reported by using aromatic additives that reduce the concentration of hexadecyltrimethylammonium bromide surfactant to ~0.05 M as opposed to 0.1 M in well-established protocols.

TL;DR: It is found that the most active oxides are, in fact, the least stable materials, and the best materials for the OER should balance stability and activity in such a way that the dissolution rate is neither too fast nor too slow.

TL;DR: This work proposes a strategy to synthesize Ag-Sn electrocatalysts with a core-shell nanostructure that contains a bimetallic core responsible for high electronic conductivity and an ultrathin partially oxidized shell for catalytic CO2 conversion, and demonstrated a remarkable performance in comparison to state-of-the-art formate-selective CO2 reduction catalysts.
