Probing P25 TiO₂ photocatalysis using photoinduced absorption spectroscopy (PIAS)

Photoinduced absorption spectroscopy of dye-sensitized nanostructured TiO2

Photoinduced absorption (PIA) spectroscopy was used to investigate dye-sensitized electrodes and solar cells under illumination conditions comparable to sunlight. In the absence of redox electrolyte, cis-RuðdcbpyÞ2ðNCSÞ2-sensitized nanostructured TiO2 films show a long-lived photoinduced charge-separation (oxidized dye molecules/injected electrons in TiO2), with a lifetime of about 10 3 s under...

Probing Galaxy evolution with Hi 21cm Absorption Spectroscopy

Probing Cu(I) in homogeneous catalysis using high-energy-resolution fluorescence-detected X-ray absorption spectroscopy.

Metal-to-ligand charge transfer excitations in Cu(I) X-ray absorption spectra are introduced as spectroscopic handles for the characterization of species in homogeneous catalytic reaction mixtures. Analysis is supported by correlation of a spectral library to calculations and to complementary spectroscopic parameters.

Probing the Mechanism of High Capacitance in 2D Titanium Carbide Using In Situ XRay Absorption Spectroscopy

(comparable only with hydrated RuO 2 ) was measured for Ti 3 C 2 T x in aqueous electrolytes. [ 11,14 ] Our previous studies revealed that spontaneous intercalation of some cations takes place when MXene samples are exposed to aqueous electrolytes. [ 6 ] In situ X-ray diffraction showed that variations of the distance between the Ti 3 C 2 T x layers (which is proportional to the c lattice param...
