A simplified ammonolysis method for synthesizing single phase TaON nanoparticles is presented and the resulting photoelectrochemical properties are compared and contrasted with as-synthesized Ta2O5 and Ta3N5. The protocol ...

High photon conversion efficiencies and low-cost materials are crucial for implementing photocatalytic solutions in large scale applications. To improve the conversion efficiencies, knowledge on the lifetime and dynamics ...

Rare earth metal doping into semiconductor oxides is considered to be an effective approach to enhance photocatalytic activity due to its ability to retard the electron–hole pair recombination upon excitation. Herein, we ...

TiO2-based materials have been extensively studied and explored in the field of catalysis. However, pristine TiO2 exhibits a wide energy band gap and fast charge recombination, restricting their large-scale applications. ...

Multilayered films of TiO2 with ordered cubic mesoporosity were grown via layer-by-layer deposition on a conductive FTO (F-doped SnO 2) substrate by dip-coating and subsequent calcination at 400°C. Since platinum nanoparticles ...

The use of light energy to drive chemical reactions has gained increasing interest for a variety of applications in the last decades. This habilitation thesis comprises a selected number of original papers from the author's ...

Future sustainable energy scenarios require an improved access to renewable energy sources and thuds help to reduce the carbon footprint of the energy sector. The dream concerning the implementation of a solar photocatalytic ...
