Development of plasmonic semiconductor nanomaterials with copper chalcogenides for a future with sustainable energy materials

Clemens Burda

The development of copper chalcogenide based nanomaterials as promising candidates for sustainable energy materials, due to their environmental compatibility and low toxicity, is presented and discussed in this review. Different solution syntheses have recently been developed for the low-cost preparation of copper chalcogenide nanocrystals, and their unique properties derived from copper deficiencies were investigated with much progress. The notorious compositional instability and defect formation of copper chalcogenide nanocrystals have been healed by forming donor–acceptor pairs in ternary and quaternary chalcogenide based nanocrystals, especially in copper zinc tin sulfides (CZTS). In addition to their use as light absorbers in solar cells, copper chalcogenide nanocrystals have also been utilized in different applications, such as electrode materials in Li ion batteries and high efficiency counter electrodes in dye/quantum dot sensitized solar cells as well as for NIR photothermal therapy. All relate to their unique copper deficiency properties. The copper chalcogenide based nanomaterials are believed to be sustainable materials for future energy applications once the syntheses and property investigations have led to a more complete understanding of their physics.

The recent development of inexpensive catalysts for the oxygen evolution reaction has suggested that efficient photoelectrochemical cells (PECs) might be constructed from terrestrially abundant materials. Because these catalysts operate in aqueous buffer solutions at neutral to slightly basic pH, it is important to consider whether electrolytic cells can have low series loss under these conditions. Water-splitting or fuel-forming PECs will likely require porous separators or electrolyte membranes to separate the cathode products from oxygen produced at the anode. For this reason we analyze the individual potential losses in electrolytic systems of buffer solutions and commercially available anion- and cation-exchange membranes. Potentiometric analysis and pH measurements were employed to measure the potential losses associated with solution resistance, membrane resistance, and pH gradient formation at the current density (25 mA cm⁻²) expected for efficient PECs. The membrane pH gradient is the most problematic source of loss in these systems, but monoprotic buffers can minimize the pH gradient by diffusion of the neutral acidic or basic form of the buffer across the membrane. These results suggest that water-splitting PECs can be viable with properly chosen membrane–buffer combinations.

Metal ions optical sensing by semiconductor quantum dots

Colloidal semiconductor nanocrystals or quantum dots (QDs) have been facilitating the development of sensitive fluorescence sensors over the past decade, due to their unique photophysical properties, versatile surface chemistry and ligand binding ability, and the possibility of the encapsulation in different materials or attachment to different functional materials, while retaining their native luminescence property. The optical metal ion chemosensors with high sensitivity and selectivity have been developed due to the importance of the metal ions' fundamental roles, possessed in a wide range of biological processes and the aquatic environment. This review addresses the different sensing strategies with chemically modified QD hybrid structures for the sensing of metal ions in aqueous solution or an in vivo environment, and discusses the photophysical mechanisms in the different sensor systems while comparing their detecting/sensing selectivity. The perspectives for the future potential developments in QD based optical sensing for metal ions are discussed.
