In-situ self-templating construction of FeNi/N co-doped 3D porous carbon from bimetallic ions-coordinated porous organic polymer for rechargeable zinc-air batteries

Medium‐Entropy Metal Selenides Nanoparticles with Optimized Electronic Structure as High‐Performance Bifunctional Electrocatalysts for Overall Water Splitting

“…It is worth noting that the peak between 1.1 and 1.4 V is the oxidation peak in the LSV of Fe-Ni based electrocatalysts. [40][41][42][43] The corresponding overpotentials of the electrocatalysts at different current densities presented in Figure 3b Furthermore, such fast kinetics could be verified by the EIS measurements (Figure 3d), from which the Fe 1.2 (CoNi) 1.8 Se 6 MESe manifests the smallest semicircle among all the specimens. Similarly, the resistance of R ct is obtained by the equivalent circuit model (inset of Figure 3d).…”

A bimetallic metal–organic framework derived MnS/CoS@C heterostructure with enhanced sodium-ion storage

“…19-0365). 28,29 For the MnS/CoS@C11 sample, it can be ascribed to the coexistence of MnS and CoS; no other peaks are found, which proves that a high purity MnS and CoS composite was synthesized by carbonization and sulfurization. Fig.…”

“…2b indicates a higher degree of disorder within the sample structure. Besides, the Gaussian peak fitting results 31,32 in Fig. 2a show that the area ratios of the D/G peaks (A D /A G ) from Fe-NC/NFC, CeO 2−x /NFC and CeO 2 -Fe 2 N/NFC −2 samples are 1.55, 2.04 and 2.14, respectively (Fig.…”
