In this study, HbTiO 2 whisker nanocomposites are prepared by incorporating TiO 2 whisker with hemoglobin (Hb). Our studies illustrate that the self‐assembled HbTiO 2 whisker films could efficiently facilitate the direct electron transfer of Hb on glassy carbon electrode (GCE). Moreover, our results demonstrate that the catalytic activity to the reduction of H 2 O 2 could be observed on the HbTiO 2 whisker modified GCE and the photovoltaic effect of TiO 2 whisker can greatly enhance the detection sensitivity of electrocatalytic reduction.
