Effects of pre-oxidation conditions on microstructure evolution and hydrogen evolution reaction performance of nano-porous Ag
Source abstract
Abstract
A novel strategy was developed to fabricate nano-porous silver (NPS) with a three-dimensional bi-continuous open porous structure. A high temperature oxidation (HTO) craft and a strong oxidant-assisted low-temperature oxidation method were used to tune the dealloying of AgXCu(1-X) ribbons. The NPS fabricated from the Ag15Cu85 ribbon by the HTO pretreatment exhibited a ligament size of ∼841 nm after 1 h of dealloying. However, the NPS fabricated from the Ag15Cu85 ribbon by the H2O2 craft exhibited a ligament size of ∼61 nm after 1 h of dealloying. In addition, the NPS fabricated by the strong oxidant-assisted dealloying craft exhibited an ultrahomogeneous ligament pore structure and a higher Tafel slope in regard to its hydrogen evolution reaction.
