{110}-exposed rutile titanium dioxide nanorods in photocatalytic performance

Abstract

Single crystalline rutile TiO2nanorods were prepared by reacting sodium titanate with hydrochloric acid. The proposed formation mechanism involves a growth pathway. The growth proceeds along [001], and the circumferential faces are {110}, which are identified as the photoactive faces of rutile titanium dioxide. Both the heterogeneous (photocatalyst only) and the combined heterogeneous/homogeneous (photocatalyst and H2O2) photocatalytic performances support its activity. The mechanism of formation and photocatalytic property are extensively studied.
