- W3049519413 abstract "LiCoO2 is a p-type semiconductor material with unique electrochemical properties that have been used intensively in rechargeable lithium-ion batteries. Due to its narrow bandgap energy (2.7 eV) other applications like UV photodetectors and photocatalysis are worth to investigate. In this work single-phase LiCoO2 was prepared by the coprecipitation method, using cobalt and lithium nitrates and formic acid. At room temperature, lithium cobalt formate was formed, whereas its calcination at 600 °C yielded the target compound. The morphology corresponds to nanostructured 3D architectures, composed by arrangements of flower-like sheets. The photocurrent properties revealed an increase on the electrical current under UV radiation, whose magnitude depends on the optical irradiance of the light source, the mobility of charge carriers and the applied bias voltage. The results obtained from the photocatalytic decomposition of malachite green revealed a degradation above 60 % in the first 20 min. X-ray photoelectron and fluorescence spectroscopy analyses suggest that the formation of OH radicals played a key role in this process." @default.
