Monodentate adsorption of oxygen intermediates results in a theoretical overpotential limit of ≈0.35 V for oxygen evolution reaction (OER), which causes the sluggish kinetics of the OER process. In this work, nonprecious chromium dopant is introduced into the self‐supported CoFe layered double hydroxides (LDHs) on nickel foam (Cr‐CoFe LDHs/NF) via a facile one‐step hydrothermal method, which exhibits...
A model of CF 3 etching Si (2×4) surface has been developed based on density functional theory. We find that the reconstruction Si surface tends to be fully F-terminated. Meanwhile, C–C chain forms spontaneously on the top of the surface to resist further F–Si interacting. Over-saturated Si bonds could still be stable as well due to the strong F–Si bonding, however, it needs to overcome an...
