Electrochemical Characterisation of the Photoanode Containing TiO2 and SnS2 in the Presence of Various Pharmaceuticals

In this work, the behaviour of photoanodes made TiO2, SnS2 and TiO2/SnS2 was examined in presence absence pharmaceuticals diclofenac (DCF), memantine hydrochloride (MEM) salicylic acid (SA). The focus current research is on following photoelectrochemical (PEC) characterisation methods: linear polarisation, electrochemical impedance spectroscopy (EIS), open circuit potential (OCP) monitoring. Linear polarisation EIS provided useful information about interaction between photocatalytic materials. selected affects OCP value, mainly due to pH change. results obtained by PEC were compared (PC) efficiency pharmaceutical degradation. addition photocurrent response, voltammogram indicates oxidation DCF SA. Geometry optimizations using density functional theory (DFT) showed that HOMO orbitals’ position SA are above TiO2 level below level. Due this, characteristic peak for registered, but only photoanodes. not registered MEM, although h+ scavenging properties noticed MEM. Apparently, an interplay protonated non-protonated forms MEM differences their positions.
