Fabrication of Zr-based Metal Organic Framework and Its Application in to Photocatalysis and Electrocatalysis by Dye Removal Studies

In this work, the photocatalytic degradation of Acid Yellow, 99 (AY 99) dye under solar light irradiation using the Zr-MOF@GNS and synthesizedZrO2isinvestigated.TheZrO2issynthesizedusingZr-metalprecursor. The prepared ZrO2 is used to synthesize Zr-MOF@GNS and it is further examined using FT-IR, PXRD and FESE Manalyses. The photocatalyticdegradationofAY99 is studied by varying the initial concentrationofAY99, the length of the irradiation period, the catalyst dose and the pH of the dye solution. From the result sit is found that the Zr-MOF@GNS is an efficient and promising catalyst for the enhancement ofphotocatalyticdegradationofAY99.ElectrochemicalstudiesshowsthatZrO2and Zr-MOF@GNS can act as electrocatalyst for acid base titrations.
