flow employed. In no way has the selection of porous structure, cell or flow geometry been optimized; these should be subjects of future investigations.
ConclusionsThis study has demonstrated the feasibility of the electrochemical reduction of EAQ dissolved in an organic solvent from an aqueous-continuous suspension flowing past an electrode. With a sufficiently high degree of turbulence, current densities and current efficiencies of industrial interest can be achieved. Although the present results are insufficient for the design or evaluation of a large-scale application of this process, it would appear that cathodic reduction of EAQ (and other water-insoluble organic compounds) in two-phase systems warrants further evaluation in the laboratory.
High efficiency (12.7%) CdSe0.68Te0.32/cesium polysulfide photoelectrochemical cells are demonstrated in this work. Crystals of the ternary alloy Cd(Se, Te) of type n type were synthesized by the traveling heater method. The nature of the polysulfide electrolyte, based on Cs polysulfide without excess hydroxide and containing small amounts of copper ions, is shown to be of particular importance in determining the cell efficiency. Reasonable output stability of the cell was obtained under accelerated tests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
