Integration of noble metals into semiconductor-based nanoparticle gel structures facilitates the extraction of photoexcited charge carriers upon illumination. While charge carrier generation takes place in the semiconductor ...

La2NiO4+δ particles with a plate-like morphology were prepared from a NaOH melt by molten-flux synthesis. For this purpose, the intermediates from a sol–gel process were used as reactants. Using powder X-ray diffraction, ...
