Abstract

An easy method to prepare platinum coatings is proposed. Platinum coatings were prepared on glass substrate by applying a thermal decomposition method. Electrochemical and surface properties of the Pt coatings obtained were studied. A polycrystalline Pt layer is formed which shows electrocatalytic activity towards oxygen reduction similar to that of bulk platinum. An amperometric oxygen sensor was constructed by using Pt-coated glass substrate as a cathode. The oxygen sensor exhibited good performance characteristics. A biosensor for the determination of biochemical oxygen demand (BOD) was developed using the oxygen sensor as a base transducer and by immobilizing bacteria Bacillus subtilis in agarose gel film on the top of the sensor's membrane. The BOD biosensor was tested in various media.
