A plasmonic Ag/TiO2 photocatalytic composite was designed by selecting Ag quantum dots (Ag QDs) to act as a surface plasmon resonance (SPR) photosensitizer for driving the visible-light driven photoelectrocatalytic hydrogen evolution. Vertically oriented hierarchical TiO2 nanotube arrays (H-TiO2-NTAs) with macroporous structure were prepared through two-step method based on electrochemical anodization. Subsequently, QDs, tunable size (1.3-21.0 nm), could be uniformly deposited H-TiO2 NTAs...
Microwave-assisted hydrothermal approach was developed as a general strategy to decorate copper nanowires (CuNWs) with nanorods (NRs) or nanoparticles (NPs) of metal oxides, sulfides, and organic frameworks (MOFs). The microwave irradiation induced local "super hot" dots generated on the CuNWs surface, which initiated adsorption chemical reactions ions, accompanied by growth assembly NPs building blocks along nanowires' surfaces. This solution-processed enables NRs @CuNWs hybrid structure...
