Rufan Zhang,Chong Liu,Po-Chun Hsu,Chaofan Zhang,Nian Liu,Jinsong Zhang,Hye Ryoung Lee,Yingying Lu,Yongcai Qiu,Steven Chu,Yi Cui +10 more
TL;DR: Here, high-efficiency polyimide-nanofiber air filters for the high temperature PM2.5 removal are developed that could effectively remove >99.5% PM particles from car exhaust at high temperature.
Journal ArticleDOI
All-solid-state hybrid solar cells based on a new organometal halide perovskite sensitizer and one-dimensional TiO2 nanowire arrays
TL;DR: A novel organometal halide perovskite (CH3NH3PbI2Br) is synthesized and used as a visible light absorber to sensitize one-dimensional TiO2 nanowire arrays (NWAs) for all-solid-state hybrid solar cells.
Journal ArticleDOI
Secondary branching and nitrogen doping of ZnO nanotetrapods: building a highly active network for photoelectrochemical water splitting.
TL;DR: A photoanode based on ZnO nanotetrapods, which feature good vectorial electron transport and network forming ability, has been developed for efficient photoelectrochemical water splitting andNitrogen-doping represents the second strategy, which yielded a photocurrent density higher than those of the corresponding nanowire devices reported so far.
Journal ArticleDOI
