Immediately after addition of the formic acid, the current is very high, but later approaches a low equilibrium value. This inhibition is due to a blockade of the platinum surface caused by the sorption of formic acid or a consecutive product. The inhibition can be suppressed by partial coverage of the platinum surface with a sulphur sorbate. At Raney-platinum electrodes in 3N H2SO4 a current density of approximately 200 mA/cm2 is attained at a temperature of 30°C and a potential of 250 mV. At 90°C the current density even reaches a steady state value of about 2 A/cm2. The large increase in the oxidation rate of formic acid by the sulphur sorbate is associated with a decrease of activation energy by about 8 kcal/ mol. The reaction rate has a maximum if the platinum surface is covered by approximately a third of a monatomic sulphur layer. The sulphur sorbate layer can easily be put on all platinum catalysts, e.g. platinum black, by a hydrogen sulfide treatment. In 3N H2SO4 at a temperature of 70°C the sorbate layer is resistant up to a potential of about 650 mV; only at higher potential starts the oxidation yielding sulphur dioxide. The sulphur sorbate resists also potassium hydroxide solution, however, the oxidation of formic acid is not accelerated in the alkaline solution.The mechanism of the anodic oxidation of formic acid in alkaline and acid electrolyte will be discussed by reference to potentiodynamic potential-current density plots.</div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"7 3","pages":"Pages 121-136"},"PeriodicalIF":0.0,"publicationDate":"1967-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(67)90008-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88314925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known, for example, that the Seebeck coefficient of intrinsic single-crystal bismuth telluride is anisotropic. Thus, measurements of the Seebeck coefficient as a function of thickness have been made on a near-intrinsic polycrystalline bismuth telluride alloy. As expected, the Seebeck coefficient falls when the sample thickness becomes smaller than the grain size. The magnitude of the effect, amounting to about 15 μV/°C, is of the order predicted from the known parameters of single crystal material, though an exact theoretical treatment of the problem has not been possible. On lowering the temperature, so that the material becomes an extrinsic conductor, the thickness-dependence of the average Seebeck coefficient disappears, since the local Seebeck coefficient is then no longer orientation-dependent.The above results were obtained using careful grinding and polishing techniques. Similar experiments carried out using coarse grinding of the samples led to an increase of the Seebeck coefficient with decreasing thickness. This effect is tentatively explained in terms of mechanical damage, notably the splitting of the grains along their basal planes.</div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"7 2","pages":"Pages 99-103"},"PeriodicalIF":0.0,"publicationDate":"1967-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(67)90015-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77038254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The region between the emitter and collector is filled with a low pressure gas whose molecules attach electrons in the space charge or become negative ions after contact with the emitter. The negative ions move to the collector by diffusion and mutual repulsion, or convective flow, where they deposit their electrons by collisional detachment. Strongly electron-attaching gases, Br2, CF2Cl2, and SF6, were tried, but they did not undergo collisional detachment and reacted with the tungsten emitter. The inert gases, He and A, had little or no effect on the collector current and were used for comparison. Very pure methane, CH4, produced collector current increases of a factor of 10 or more when added to the thermionic converter. Experiments performed in a magnetic field showed that the collector current was due to the diffusion of negative ions, as well as electrons. An experiment having a mass flow of methane over the emitter to the collector showed the transfer of electricity by negative ions. Photoionization or photodecomposition did not account for the negative ion formation. The mechanism whereby CH4 forms negative ions is unknown.</div>","PeriodicalId":100032,"journal":{"name":"Advanced Energy Conversion","volume":"7 2","pages":"Pages 113-120"},"PeriodicalIF":0.0,"publicationDate":"1967-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0365-1789(67)90017-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90743579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
