Congratulations to Fengli Yang on recent paper published in “Applied Catalysis B: Environmental” Facile synthesis of highly efficient Pt/N-rGO/N-NaNbO3 nanorods toward photocatalytic hydrogen production

Highly efficient and stable Pt/N-rGO/N-NaNbO3 nanorod photocatalysts were prepared by a facile two-step hydrothermal method for the first time. An excellent hydrogen evolution rate of 2342 μmol g−1 h−1 is attained by 0.5%Pt/0.5%N-rGO/N-NaNbO3 under mimic sunlight irradiation, which is evidently higher than those of both the pristine NaNbO3 nanorod (241 μmol g−1 h−1) presented in this work and several modified NaNbO3 catalysts reported in the preceding literatures. Such a huge improvement in the photocatalytic performance is mainly attributed to the narrowed band gap of NaNbO3 nanorod by the doping of nitrogen element, the increased light absorption over the entire range of wavelength by the introduction of N-rGO, and the reduced electron-hole recombination rate by the excellent electron transfer properties of N-rGO and Pt nanoparticles. This innovative work may suggest a meaningful approach for developing a more appealing and practical method to modify sodium niobate for photocatalytic hydrogen generation.
