On the role of metal particle size and surface coverage for photo-catalytic hydrogen production: A case study of the Au/CdS system

Photocatalytic degradation of textile dyes on Cu2O-CuO/TiO2 anatase powders

“…explanation is yet known [37], [38], [39], [34] and [40]. Upon increasing of metal particle coverage, large fraction of the semiconductor surface may become unavailable for light absorption.…”

Comparative activity of CdS nanofibers superficially modified by Au, Cu, and Ni nanoparticles as co-catalysts for photocatalytic hydrogen production under visible light

“…The use of CdS semiconductors for photocatalytic applications has attracted much attention since it can be activated in the visible light region; specifically, it has recently been reported for photocatalytic hydrogen production . Different routes of synthesis leading to particular structures and morphologies, such as nanospheres nanorods, nanofibers, nanowires, nanoflowers have been obtained and reported since this semiconductor has the advantage of absorbing throughout the visible region from 300 to 500 nm.…”

Comparing the Reaction Rates of Plasmonic (Gold) and Non-Plasmonic (Palladium) Metal Particles in Photocatalytic Hydrogen Production

“…The development of an active, scalable and stable photocatalyst remains one of the biggest challenges in modern day catalysis. Many families of semiconductors have been made and tested including oxide semiconductors such as TiO 2 , ZnO, WO 3 , BiVO 4 , [1][2][3][4] sulfide semiconductors such as CdS, ZnS, Mo x S y , [5][6][7] and nitride semiconductors such as GaN, InGaN, C 3 N 4 [8][9][10]. These semiconductors alone or in mixed forms including solid solutions and abrupt interfaced materials such as layer by layer growth or layer Abstract Both Pd and Au metal particles are used in photocatalytic hydrogen generation.…”
