In this paper, for the first time we have developed a new and
simple formaldehyde sensor based on photoelectrocatalytic
determination using Ti/TiO2 electrode prepared by anodizing Ti
foil in aqueous solution. The sensor showed promising determination
of formaldehyde with good detection limit. The Ti/TiO2
electrode can be prepared simply and successfully used as an
amperometric sensor for formaldehyde determination in real
sample with suitable precision and accuracy.
