In addition to a variety of etching procedures, several other surface treatments have been used to improve photoelectrode performance. Examples include a Ga ion dip for CdSe (Tomkiewicz et al, 1982), a ZnCl2 dip for thin-film CdSe (Hodes et al, 1980 Reichman and Russak, 1982), and the deposition of Ru on GaAs (Parkinson, et al, 1979) and on InP (Heller, 1982), and Cu on CdSe (Flaisher et al, 1984). Reasons advanced for the effectiveness of these treatments range from a suppression of dark current to electrocatalysis by surface-deposited metal atoms. [Pg.604]

As occurring for thin films of redox polymers, there are three elements of porous electrode behavior crucial to its performance in electrocatalysis the transport of a solution reactant to the catalytic sites within the porous system, the transport of electrolyte charge-balancing ions, and the electron transport across the solid, a process responsible for the regeneration of the initial oxidation state of the catalyst. [Pg.51]

Pt-Mo-N thin films have been investigated for formic acid and methanol oxidation [92]. PtMoN showed enhanced activity over an equivalent PtMo alloy for both reactions indicating that the nitride phase improves the electrocatalysis. [Pg.315]

Microelectrodes with high real surface areas and well-defined periodic nanostmctures have recently attracted much interest because of their potential applications in electrocatalysis and electroanalysis [94-96]. These electrode systems can be prepared, using templating techniques, from lyotropic liquid crystalline phases of nonionic surfactants [94,95]. In particular, the normal topology hexagonal (Hj) liquid crystalline phase has been used as a template for the synthesis of mesoporous metal thin films via the electrochemical reduction of metal salts dissolved in the aqueous domain of the liquid crystalline phases [119, 120]. [Pg.228]

In nanoparticle electrocatalysis, the area that Michael entered just some time ago in Munich, he and his coworkers rationalized the sensitivity of electrocatalytic processes to the stmcture of nanoparticles and interfaces. Studies of catalytic effects of metal oxide support materials revealed intriguing electronic structure effects on thin films of Pt, metal oxides, and graphene. In the realm of nanoparticle dissolution and degradation modeling, Michael s group has developed a comprehensive theory of Pt mass balance in catalyst layers. This theory relates surface tension, surface oxidation state, and dissolution kinetics of Pt. [Pg.556]

Organic thin films have been extensively investigated in connection with the attempts to apply organic materials to electronic and electrochemical devices. Phthalocyanine and its metallo-derivatives are particularly of interest in this field a wide variety of physical and physicochemical properties applicable to such devices, i.e., photo-conductivity, photovoltaic effect a, electrochromism, electrocatalysis , have been reported for their films. [Pg.515]

Thin metal films have been used as model catalysts not only in electrocatalysis (27-34) but also to study enantioselective hydrogenation catalyzed by supported platinum and palladium catalysts modified by adsorbed chiral compounds (39-44). [Pg.238]

Solid-state electrochemistry — is traditionally seen as that branch of electrochemistry which concerns (a) the -> charge transport processes in -> solid electrolytes, and (b) the electrode processes in - insertion electrodes (see also -> insertion electrochemistry). More recently, also any other electrochemical reactions of solid compounds and materials are considered as part of solid state electrochemistry. Solid-state electrochemical systems are of great importance in many fields of science and technology including -> batteries, - fuel cells, - electrocatalysis, -> photoelectrochemistry, - sensors, and - corrosion. There are many different experimental approaches and types of applicable compounds. In general, solid-state electrochemical studies can be performed on thin solid films (- surface-modified electrodes), microparticles (-> voltammetry of immobilized microparticles), and even with millimeter-size bulk materials immobilized on electrode surfaces or investigated with use of ultramicroelectrodes. The actual measurements can be performed with liquid or solid electrolytes. [Pg.620]
