Non-noble metal copper nanoparticles-decorated TiO2 nanotube arrays with plasmon-enhanced photocatalytic hydrogen evolution under visible light

Non-noble metal Cu nanoparticles were loaded on the TiO2 nanotube arrays (Cu/TNAs), which showed an excellent visible-light-driven photocatalytic performance for efficient and stable hydrogen evolution without the Pt co-catalyst due to the surface plasmon resonance (SPR) of Cu nanoparticles.390
