Advancing overall water splitting via phase-engineered amorphous/crystalline interface: A novel strategy to accelerate proton-coupled electron transfer

Engineering hierarchical snowflake-like multi-metal selenide catalysts anchored on Ni foam for high-efficiency and stable overall water splitting

“…From the XPS of high-resolution Co 2p, peaks at 803.68 eV and 785.18 eV in W-CoO/NF correspond to Sat, while the main peaks of binding energy of 797.38 eV and 781.38 eV are attributed to Co 2p 1/2 and Co 2p 3/2 , respectively. 36–39 After selenization, the peak positions of W-CoSe300/NF are 802.68 eV and 785.08 eV and the peak positions of Co 2p 1/2 and Co 2p 3/2 are 796.68 eV and 780.68 eV (Fig. 3c).…”
