Revealing the Role of TiO <sub>2</sub> Blocking Layers in Hematite Photoanodes through Activation Energy Analysis of Back Recombination via in Situ Near-Field Heterodyne Transient Grating Spectroscopy
acts as an effective blocking layer and the activation energy of back recombination serves as a physically meaningful quantitative metric for evaluating and comparing the effects of the blocking layer in hematite photoanodes.
