Both Pd and Au metal particles are used in photocatalytic hydrogen generation. Yet while both act as electron sink only gold is poised to respond to visible light due to its plasmonic response. In order to quantitatively gauge their relative contribution into the reaction, the photocatalytic H2 production, from Au/TiO2 and Pd/TiO2 catalysts was studied under UV and UV–Vis light. While under UV light...
H2-production from renewables using sunlight is probably the holy grail of modern science and technology. Among the many approaches for increasing reaction rates, by increasing light absorption, plasmonic materials are often invoked. Yet, most plasmonic metals on semiconductors are also good for Schottky barrier formation. In this work, we are presenting evidences of de-coupling the plasmonic from...
This paper presents an analytic way of sizing an electrolyser by considering the load requirements and efficiencies of the electrolyser, fuel cell and their ancillaries. Current density and the size of the active area of the membrane are optimised to ensure thermal self-sustaining mode of the electrolyser for stand-alone applications. This eliminates the need of heating the feed water. Correlations...
