Multisite engineering towards atomically dispersed Ru on Ni-Co-P composite with N-doped carbon matrix for robust water oxidation

Amorphous Ru Coupled with Defect-Abundant B-Doped FeP4/Fe2P Porous Nanospheres as an Electrocatalyst for Hydrogen Generation with a Wide pH Range

“…The M–P bond in Ru/B- p -FeP 4 /Fe 2 P has a slight negative shift compared with B- p -FeP 4 /Fe 2 P, indicating that P may act as proton acceptors during the catalytic process . After introducing Ru, the Fe 2p spectra show a positive shift, while P presents a negative shift; , the increased difference leads to a higher local electric dipole, which decreases the energy potential barrier of the electrocatalytic process and facilitates the catalytic reaction …”

“…39 The M−P bond in Ru/B-p-FeP 4 /Fe 2 P has a slight negative shift compared with B-p-FeP 4 /Fe 2 P, indicating that P may act as proton acceptors during the catalytic process. 43 After introducing Ru, the Fe 2p spectra show a positive shift, while P presents a negative shift; 56,63 the increased difference leads to a higher local electric dipole, which decreases the energy potential barrier of the electrocatalytic process and facilitates the catalytic reaction. 64 A typical three-electrode configuration was utilized to investigate the electrocatalytic performance of Ru/B-p-FeP 4 / Fe 2 P and other contrast samples in 0. indicating that both the introduced amorphous Ru and porous structure benefit to improve the HER performance.…”
