| Abstract | |
We discuss the photoelectroanalytical performance of a brookite-phase titanium dioxide (TiO2) platform electrodeposited onto graphene foam (GF) at low temperatures. The scalable electrosynthesis process eliminates the need for thermal annealing, which is impractical for carbon-based electrodes. Films resulting from a 10 min electrodeposition (TiO2-10/GF) exhibit enhanced photocurrents, reaching 170 mu A cm-2 GEO-twice the value for TiO2 films on traditional screen-printed carbon electrodes (82 mu A cm-2 GEO). The increased photocurrent density makes TiO2-10/GF ideal for on-site photoelectrochemical biosensors as it allows for the use of compact systems with low-power LEDs. (AU) | |
