Combinatorial development of nanoporous WO3 thin film photoelectrodes for solar water splitting by dealloying of binary alloys

Applications of high throughput (combinatorial) methodologies to electronic, magnetic, optical, and energy-related materials

“…The efficient renewable production of sufficiently pure hydrogen represents a significant challenge that must be addressed in conjunction with the search for suitable hydride materials. High-throughput efforts in the field of solar energy splitting of water have been developed by several groups, [272][273][274] and a recent critical review on this subject has been published. 275 Despite these advantages, the implementation of metal and chemical hydrides has been hindered by the dehydrogenation thermodynamics and kinetics of typical materials.…”

Advanced and In Situ Analytical Methods for Solar Fuel Materials

“…Different techniques, including ink-jet printing [157,176], sputtering [172], and electrodeposition [143,177], have been implemented to create the photocatalyst libraries on a small electrode. The photocatalyst spot arrays fabricated using a piezoelectric dispensing tip is an example of the material collections for the rapid screening with SECM [178].…”

“…Combinatorial screening coupled with rapid synthesis have been employed as versatile tools for the discovery of many biological, organic, and inorganic materials with specific properties needed for different applications [171]. The tools have also been utilized to develop promising multi-component photocatalysts for solar energy conversion devices [143,146,157,172,173]. This chapter mainly deals with the rapid screening of photocatalysts using SECM [174,175] and also briefly describes in situ electrochemical characterization of photoelectrodes using SECM techniques.…”

Engineering the Morphology and Crystal Phase of 3 D Hierarchical TiO2 with Excellent Photochemical and Photoelectrochemical Solar Water Splitting

“…[4,5] Photochemicalw ater splitting generally dependso ns everal factors, for example, 1) generation of electrons and holes through photon absorption by the semiconductor,2 )separation of the photogenerated electron-hole pairs and 3) transport of charge carriers to the surface of the semiconductor to drive the chemical reactions. [6] Innumerous materials have been investigated, and different approaches, such as doping, [7][8][9] combinatorial methods, [10,11] and heterojunction formation, [12][13][14][15] have been employed to enhanceH 2 generation performance. Among these approaches, designing heterojunctions with varying potentiald istribution is considered to be an effective approach toward water splitting owing to strong electron-hole pair separationa nd transportatione fficiency through the heterojunction interface.…”
