Abstract Recently nitrogen-hydrogen compounds have successfully been applied as co-catalysts for mild conditions ammonia synthesis. Ca2NH was shown to act as a H2 sink during reaction, with H atoms from its lattice being incorporated into the NH3(g)

Bi-phasic O3/P2 sodium layered oxides are leading candidates for next-generation batteries but rational control of the O3/P2 ratio remains challenging. Here, the O3/P2 ratio is tuned by using the average ionic radius of the transition metal layer, le

Metal/semiconductor interactions affect electron transfer rates and this is central to photocatalytic hydrogen ion reduction. While this interaction has been studied in great detail on metal oxide semiconductors, not much is known of Au particles on

Ti-substituted MnNb2O6 samples have been prepared to enhance conductivity via introduction of oxygen vacancies or hole formation. The single phase MnNb2-xTixO6-δ columbite existence range is narrow (0 < x < 0.2). The effect of the substitution on el

Many of the key issues facing solid-oxide fuel cell (SOFC) technology development may be addressed by finding improved electrode materials. These include lower temperature of operation, fuel flexibility, and sulfur and chromium tolerance. Here we rev
