Functionalization of semiconductors by metallic nanoparticle is considered to be one the most effective procedure improve photocatalytic hydrogen production. Photodeposition frequently used for functionalization but particle sizes and dispersions are still difficult control. Here, Pt achieved in a one-pot synthesis. The as-prepared samples compared reference materials prepared conventional photodeposition our results confirm that small well-dispersed nanoparticles with superior stability...
Abstract There is great interest in the development of alternatives to noble metals for plasmonic nanostructures. Transition metal nitrides are promising due their robust refractory properties. However, photophysics these nanostructures, particularly hot carrier dynamics and photothermal response on ultrafast timescales, not well understood. This limits implementation applications such as catalysis or solar thermophotovoltaics. In this study, light‐induced relaxation processes...
Dye-sensitized photoelectrochemical (DSPEC) water splitting is an attractive approach to convert and store solar energy into chemical bonds. However, the conversion efficiency of a DSPEC cell typically low due poor performance photocathode. Here, we demonstrate that Cu-doping improves functionalized NiO-based photocathode significantly. Femtosecond transient absorption experiments show longer-lived photoinduced charge separation for Cu:NiO-based relative undoped analogue. We present...
Abstract Solid‐state nanopores are implemented in new and promising platforms that capable of sensing fundamental biomolecular constituents at the single‐molecule level. However, several limitations drawbacks remain. For example, current strategies based on both electrical optical suffer from low analyte capture rates challenging nanofabrication procedures. In addition, their limited discrimination power hinders application detection complex molecular constructs. contrast, Raman spectroscopy...
Plasmonic sensitization of semiconductors is an attractive approach to increase light-induced photocatalytic performance; one method use plasmonic nanostructures in core@shell geometry. The occurrence and mechanism synergetic effects photocatalysis such geometries are under intense debate proposed occur either through charge transfer (CT) or thermal effects. This study focuses on the relation between dimensions Ag@CeO2 nanocubes, wavelength-dependent efficiency, direct CT. A...
