This review captures the synthesis, assembly, properties, and applications of copper chalcogenide NCs, which have achieved significant research interest in the last decade due to their compositional and structural versatility. The outstanding functional properties of these materials stems from the relationship between their band structure and defect concentration, including charge carrier concentration and electronic conductivity character, which consequently affects their optoelectronic, optical, and plasmonic properties. This, combined with several metastable crystal phases and stoichiometries and the low energy of formation of defects, makes the reproducible synthesis of these materials, with tunable parameters, remarkable. Further to this, the review captures the progress of the hierarchical assembly of these NCs, which bridges the link between their discrete and collective properties. Their ubiquitous application set has cross-cut energy conversion (photovoltaics, photocatalysis, thermoelectrics), energy storage (lithium-ion batteries, hydrogen generation), emissive materials (plasmonics, LEDs, biolabelling), sensors (electrochemical, biochemical), biomedical devices (magnetic resonance imaging, X-ray computer tomography), and medical therapies (photochemothermal therapies, immunotherapy, radiotherapy, and drug delivery). The confluence of advances in the synthesis, assembly, and application of these NCs in the past decade has the potential to significantly impact society, both economically and environmentally.

The electrochemical reduction of CO2 provides an alternative carbon‐neutral path for renewable synthesis of fuels and value‐added chemicals. This work demonstrates that dendritic, bimetallic Cu–Bi electrocatalysts with nanometer‐sized grains are capable of formate generation with a high selectivity. Optimizing composition of electrocatalyst could achieve a faradic efficiency of 90 % at −0.8 to −0.9 VRHE, and a partial current of more than 2 mA cm−2. The combination of Cu with Bi enables modulation of the adsorption strength of intermediates. This leads to an increased selectivity and suppressed formation of spurious species, especially hydrogen and CO. Comparison of product distribution for Cu–In versus Cu–Bi indicated that Bi is essential to induce a favorable adsorption configuration of the intermediate species and to promote formate production.

Ethylene is one of the most widely used chemical compounds. It is readily transformed to a variety of useful products that can replace those derived from fossil sources. Further, the ability to produce ethylene from atmospheric carbon dioxide would significantly assist in the urgent need to stabilize, and ultimately to reduce, the concentration of greenhouse gases in the atmosphere. This review covers the electrochemical reduction of carbon dioxide at copper‐based cathodes. The direct production of ethylene is the focus of the review, but it is also relevant to include the important ethylene precursor and intermediate in the carbon dioxide reduction reaction, carbon monoxide. Carbon monoxide can be reduced to ethylene on a copper cathode under similar conditions to carbon dioxide. Ethanol is another potential product of the reduction of carbon dioxide at a copper cathode. It can be readily dehydrated to ethylene, further enhancing the overall yield of ethylene. The aim of the review is to show that there are many interacting parameters that influence the effectiveness and efficiency of the electrochemical reduction of carbon dioxide at copper‐based cathodes.
