Abstract |
Developing low-cost and efficient electrodes for hydrogen evolution reaction (HER) under neutral electrolytes remains an unattained milestone. We report a highly performing binder-free electrode through electroless deposition of Ni-P nanoparticles on bacterial cellulose (BC). Not needing carbonization to provide the electric conductivity, BC can maintain its excellent mechanical properties and thin fiber microstructure. The nano -metric cellulose fibers facilitate the formation of small Ni-P nanoparticles, leading to more catalytic active sites. The obtained Ni-P/BC electrode presents remarkable HER activity with an overpotential of only 161 mV at 10 mA cm(-2) and a low Tafel slope (141 mV dec(-1)) in 1 M potassium phosphate-buffered saline (pH = 7) electrolyte. Besides, Ni-P/BC also ex-hibits good stability for 24 h at 10 mA cm(-2). This binder-free, low-cost, and easily fabricated electrode holds excellent promise for HER applications in benign neutral environments. (C) 2022 Hydrogen Energy Publications LLC.
