文摘

Photo-assisted self-optimizing of charge-carriers transport channel is realized in copper species/TiO2 electrospun nanofibers. CuO/TiO2 nanofibers can be recrystallized to form Cu/Cu2O/CuO/TiO2 nanofibers during photocatalytic process. Dynamics difference of excitons migration is responsible for the self-optimization of charge-carriers transport channel. 40-fold enhanced H2 generation was observed on the recrystallized nanofibers during photocatalytic decomposition of formic acid.
