Optical and electrochemical properties of ordered macroporous gold array on the ITO surface

► In this work, we presented a new type of OTEs material-macroporous gold array. ► The SEM pictures exhibits that the close-packed macropore constituted the gold array of large area, and the absorbance spectrum indicates that macroporous gold array has excellent light transmission, so it was used to optically transparent electrode. ► The OTE was successfully served as work electrode of thin-layer cell in order to evaluate electrochemical and light properties of macroporous gold array. ► In summary, the MGA with excellent performance offers a new choice for electrode material of light transmission, and a new application field of macroporous material is opened up.
