High Entropy Pr‐Doped Hollow NiFeP Nanoflowers Inlaid on N‐rGO for Efficient and Durable Electrodes for Lithium‐Ion Batteries and Direct Borohydride Fuel Cells

“…Moreover, the D Li+ value for NiFeP/N‐rGO varies from 8.9×10 −16 to 3.2×10 −12 cm 2 s −1 (charging) and 2.87×10 −15 to 1.6×10 −10 cm 2 s −1 (discharging). Thus, the NiPr 0.5 FeP/N‐rGO electrode exhibited a relatively higher D Li+ value compared to the NiFeP/N‐rGO, which might be due to a better contact of electrolyte and electrode because of a larger active surface area and effective Li + diffusion pathways [60] …”

“…Thus, the NiPr 0.5 FeP/N-rGO electrode exhibited a relatively higher D Li + value compared to the NiFeP/N-rGO, which might be due to a better contact of electrolyte and electrode because of a larger active surface area and effective Li + diffusion pathways. [60] Figure 5 and S11 show the CV curves to investigate the kinetics and the mechanism of energy storage behavior of NiPr 0.5 FeP/N-rGO and NiFeP/N-rGO at various sweep rates. The anodic peaks moved to further positive potential and the cathodic peaks positioned towards more negative potential with increasing sweep rates, demonstrating a gradually improved electrode This is consistent with the increasing polarization voltage of the discharge/charge plateau during the rate power measurements, ohmic resistance, and diffusion constraints.…”

Three-dimensional graphene/metal–organic framework composites for electrochemical energy storage and conversion

“…Then the resultant HoCo 3 O 4 /NS-RGO composite could be achieved via further annealing the Co@ Co 3 O 4 /NS-RGO in 250 °C air for 2 h. Besides, the corresponding derived metal oxides can also be prepared through a one-step carbonization process in an inert gas. 54,93…”

“…In addition, many other 3DG/MOF-derived metal compounds ( e.g. , 3DG/Fe 7 Se 8 @C, 80 HoCo 3 O 4 /NS-RGO, 92 Fe 3 O 4 @C/RGO, 93 NC@CoO x @GF, 95 PGF@pFe 2 O 3 NF, 96 HAGO/Co@CN 43 ) have been constructed for LIB electrode materials. For example, Wang et al reported a ZIF-67-derived Co@CN modified horizontally aligned GO array (HAGO/Co@CN) as an independent anode for LIBs.…”

Synthesis and characterization of ZnBTC-based MOFs: effect of solvents and salt

“…Trimesic acid and its derivatives are available and ecofriendly substances that can be used as intermediate pharmaceutical products and as drug delivery agents as parts of MOF [34,35]. There are many publications on MOFs based on Ni [36], Fe [37], Co [38,39] and other metals [40], where trimesic acid played the role of a ligand [41][42][43]. Basically, these publications investigated the possible applications MOF: catalysis [44][45][46], medicine [47,48], adsorption [49][50][51], sensors [52][53].…”
