A new multilayered (Au NPs/TiO2/Au) photoelectrode boosts ability of solar water-splitting to produce hydrogen. According to the research team, this special photoelectrode, inspired by the way plants convert sunlight into energy is capable of absorbing visible light from the sun, and then using it to split water molecules (H2O) into H2, O2.
This multilayered photoelectrode takes the form of 2D hybrid metal-dielectric structure, which mainly consists of 3 layers of gold (Au) film, ultrathin TiO2 layer (20 nm), and gold nanoparticles (Au NPs)...
