Fabrication of superaerophobic Ru-doped c-CoSe2 for efficient hydrogen production

“…S3b, † the FT-IR spectrum of Co-ZIF/CC exhibits a series of absorption peaks, which are identied as the bending vibration peaks of Co-N (∼425 cm −1 ) and the imidazole ring (∼750 cm −1 ), the in-plane bending and stretching vibration peaks of the imidazolate ring (∼992-1304 cm −1 and ∼1460 cm −1 ) and the stretching vibration peak of C]N (∼1585 cm −1 ). 41 As a result, the SEM, XRD and FT-IR results demonstrate the successful formation of a Co-ZIF microleaf array on CC (Fig. S3c †).…”

“…2f, the binding energies for C 1s peaks at 284.6 and 285.5 eV are consistent with the bonding states of CC and CN for o-CoSe 2 /CC. 41 For Ru-c-CoSe 2 /CC-3, additional doublet Ru 3d peaks at 280.4 and 284.4 eV can be observed, 45 indicating that Ru atoms have been successfully doped into the matrix of c-CoSe 2 . High-resolution N 1s XPS spectra in Fig.…”

An interface-engineered Co2P/CoMoP2 heterojunction with greatly improved electrocatalytic activity in water/seawater splitting

“…22 Additionally, Wei et al reported a porous leaf-like hollow-structured Co 2 P@C catalyst with a phytic acid (PA)-assisted phosphidation strategy achieving low overpotentials of 127 and 157 mV in 0.5 M H 2 SO 4 and 1 M KOH, respectively. 23 The above research results showed that Co 2 P exhibits good HER activity in acidic environments. There are also relevant data comparisons in Men's work, where the preparation of Co 2 P nanorod arrays grown on carbon cloth, at a current density of 10 mA cm −2 , posed the overpotential of 83 mV in 0.5 M H 2 SO 4 , while it decreased to 110 mV in 1 M KOH.…”

“…4c and Table S1,† e.g. Co 2 P@3D-rGO ( η 10 = 36.5 mV), 44 Co 2 P/CoWO 4 ( η 10 = 81 mV) 45 and Co 2 P@C ( η 10 = 157 mV), 23 the electrocatalytic activity of Co 2 P/CoMoP 2 showed obvious advantages for the HER process in an alkaline environment.…”
