Abstract

Abstract: It is very crucial to design and prepare environmentally friendly, efficient and sustainable oxygen evolution reaction (OER) catalysts for water splitting reaction. In this work, a series of Fe–Co–B nanosheets with different molar ratio of Fe/Co precursor have been recombined with bacterial cellulose based carbon nanofiber (BCCNF) through simple electroless deposition method at room temperature. It is indicated that, when the Fe/Co molar ratio is 1:3, Fe–Co–B/BCCNF exhibits an excellent catalytic property with overpotential of only 160 mV at 10 mA cm −2 . Furthermore, it displays a prominent electrochemical stability, even over 30 h of OER process under alkaline condition. The strategy of designing 3D nanostructure and constructing metal-boride-based catalyst for OER provides valuable insights into efficient oxygen evolution. Graphical abstract: Shown up is the fabrication procedure for Fe–Co–B/BCCNF materials. Image 1 Highlights: Bacterial cellulose based carbon nanofiber (BCCNF) is prepared by pyrolysis. Highly dispersed Fe–Co bimetallic catalyst is prepared by easy electroless deposition. FCB-3/BCCNF catalyst shows exceedingly low overpotential of 160 mV at 10 mA cm −2 . FCB-3/BCCNF catalyst exhibits eminent stability and holds steady even during 36 h OER.
