Tribocatalytic investigation of BaTiO3 for dye removal from water

In the present work, we employed BaTiO3 powder as tribocatalyst for removing dye, a representative pollutant from the water via tribocatalysis process. In tribocatalysis experiments, it was demonstrated that BaTiO3 powder acting as a tribocatalyst, can effectively eliminates organic dyes due to the triboelectric effect occurring between glass and PTFE/Teflon interface. Additionally, the tribocatalytic performance of BaTiO3 powder was also investigated by varying the size and speed of the used PTFE. The maximum degradation for Methylene Blue (MB) and Rhodamine B (RB) dyes was similar to 57 and similar to 82% in 12 h, respectively. This work not only establishes an environmentally friendly method for the oxidative purification of organic contamination but also presents a hopeful approach which could be used in sustainable energy production and environmental remediation.
