High surface area titania lyogels have been prepared, thermally transformed into TiO2 polymorphs at 400–850 °C, and decorated by ball milling with preformed Au nanoparticles of ca. 2 nm to ensure the same contact points at the metal–support inte

Publikováno v: Langmuir : the ACS journal of surfaces and colloids. 34(32)

Plasmonic nanoparticles, especially gold ones, have been widely employed as photosensitizers in photoelectrovoltaic or photocatalytic systems. To improve the system's performance, a greater interaction of the nanoparticles with the semiconductor, gen

Topochemical nitridation in ammonia at moderate temperatures of cation ordered Sr2FeWO6 produces new antiferromagnetic double perovskite oxynitrides Sr2FeWO6-xNx with 0 < x ≤ 1. Nitrogen introduction induces the oxidation of Fe2+ to Fe3+ and decrea
