Templating colloidal sieves for tuning nanotube surface interactions and optical sensor responses

Daniel Jerôme Siefman, Ardemis Anoush Boghossian, Shang-Jung Wu, Benjamin Paul Johanès Gabriel Lambert, Alice Judith Gillen

Surfactants offer a tunable approach for modulating the exposed surface area of a nanoparticle. They further present a scalable and cost-effective means for suspending single-walled carbon nanotubes (SWCNTs), which have demonstrated practical use as fluore ...

Low-cost high-efficiency system for solar-driven conversion of CO2 to hydrocarbons

Ulf Anders Hagfeldt, Silver Hamill Turren Cruz

Conversion of carbon dioxide into hydrocarbons using solar energy is an attractive strategy for storing such a renewable source of energy into the form of chemical energy (a fuel). This can be achieved in a system coupling a photovoltaic (PV) cell to an el ...

Photoelectrocatalytic arene C–H amination

Xile Hu, Laurent Liardet, Jingshan Luo, Lei Zhang, Dan Ren

Photoelectrochemical cells are widely studied for solar energy conversion. However, they have rarely been used for the synthesis of high added-value organic molecules. Here we describe a strategy to use haematite, an abundant and robust photoanode, for non ...

Atomically dispersed Fe3+ sites catalyze efficient CO2 electroreduction to CO

Xile Hu, Lichen Bai, Jun Gu

Currently, the most active electrocatalysts for the conversion of CO2 to CO are gold-based nanomaterials, whereas non-precious metal catalysts have shown low to modest activity. Here, we report a catalyst of dispersed single-atom iron sites that produces C ...
