The reduction of sulphur dioxide by carbon monoxide on a La0.5Sr0.5CoO3 catalyst

Autor: Alfred C. C. Tseung, D. Brynn Hibbert

Publikováno v: Journal of Chemical Technology and Biotechnology. 29:713-722

The semiconducting perovskite oxide, La0.5Sr0.5CoO3, is a catalyst for the reduction of sulphur dioxide by carbon monoxide. Unlike aluminia-supported metal catalysts, La0.5Sr0.5CoO3 tolerates high levels of oxygen in the gas stream if sufficient carb

An electrochemical alcohol sensor based on a co-electrodeposited Pt∣WO3 electrode

Autor: Y Chen, A. C. C. Tseung, K.Y Chen

Publikováno v: Journal of Electroanalytical Chemistry. 471:151-155

Previous studies by Tseung et al. have shown that co-electrodeposited Pt ∣ WO 3 acts as a very effective bi-functional anode catalyst for the oxidation of low molecular weight compounds at low overpotentials and is less susceptible to poisoning by

A preliminary study of room temperature direct ethyl formate fuel cells for consumer electronic applications

Autor: Kun Yao Chen, A. C. C. Tseung

Publikováno v: Journal of Electroanalytical Chemistry. 451:1-4

There is an increasing interest in the development of room temperature fuel cells for consumer electronic applications. Ethyl formate is an ideal fuel–more reactive than methanol and relatively harmless. An attempt to construct an ethyl formate roo

Effect of Nafion Dispersion on the Stability of Pt / WO 3 Electrodes

Autor: A. C. C. Tseung, K. Y. Chen

Publikováno v: Journal of The Electrochemical Society. 143:2703-2707

Coelectrodeposited Pt/WO{sub 3} electrodes have very high activity for the oxidation of methanol and formic acid. However, WO{sub 3} has a slight solubility at 60 C in sulfuric acid media and this significantly reduces its activity and stability. By

Factors affecting the dissolution and reduction of oxygen in molten carbonate electrolytes. Part II: Effect of SrCO3, BaCO3 and SnO2 additives

Autor: R.W. Reeve, A. C. C. Tseung

Publikováno v: Journal of Electroanalytical Chemistry. 403:85-91

The effect of minority SrCO 3 , BaCO 3 , and SnO 2 additions to various alkali carbonate electrolytes has been investigated for both oxygen reduction kinetics and also oxide ion activity. Although alkaline earth metal additives were found to assimila
