摘要：
Controlled synthesis of carbon nitride nanostructures doped with noble metal-based catalysts is important in various catalytic applications. Herein, we developed a scalable, facile, and template-free approach for one-pot synthesis of one-dimensional gC(3)N(4) nanofibers co-doped with Au and Pd donated as (Au/Pd/gC(3)N(4)NFs). The developed method tailored the high mass production of uniform gC(3)N(4) nanofibers with a great surface area of (85 m(2) g(-1)) and coherently co-doped with Au and Pd. Intriguingly, the complete CO oxidation temperature of Au/Pd/gC(3)N(4)NFs (144 degrees C) is significantly lower than that of Pd/gC(3)N(4)NFs (191 degrees C) and Au/gC(3)N(4)NFs (205 degrees C). The superior activity of Au/Pd/gC(3)N(4)NFs is attributed to the combination between outstanding inherent catalytic merits of Au/Pd and the unique physicochemical properties of gC(3)N(4) nanofibers. Our newly designed simple approach may open the way for utilization of gC(3)N(4) nanofibers in CO oxidation reaction. (C) 2019 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
