Modification effects of porphyrin dyes on the photocatalytic activity of tantalum (oxy)nitride (TaON) were investigated. The nitrogen content in tantalum (oxy)nitride was increased by increasing the heat treatment period. The optimized nitridation co

YCoO3 is discussed as a novel cathode material for solid oxide fuel cells (SOFCs). One of the major issues for SOFC development is the side reactions that occur at the electrode and electrolyte interfaces. Characteristics such as the phase stability,

Pt-loaded TiO2 (Pt/TiO2) catalysts for photocatalytic water splitting were prepared by the polygonal barrel-sputtering method. The results showed that the evolution rates of H2 and O2 gases for our Pt/TiO2 catalysts were ca. 5–10 times of those pre
