High energy ball-milling preparation of Co–B amorphous alloy with high electrochemical hydrogen storage ability

Synthesis, characterization and investigation of electrochemical hydrogen storage capacity in tin hexaferrite nanostructures

“…Based on the data, the discharge capacity enhanced from 360 mAh/g in the first cycle to 2050 mAh/g after 15 cycles. In Table 1 discharge capacity for some materials with different structures is presented 27‐31 . As can be observed, the present work shows the SnFe 12 O 19 /MWCNTs nanocomposite creates an efficient role for hydrogen storage.…”

Facile synthesis of Co2P via the reduction of phosphate with KBH4 for nickel-based rechargeable batteries

“…1. Co-P obtained from chemical reduction keeps a typical amorphous feature, as indicated by a broad peak located at a 2h value of around 45° [30,31]. For Co 2 P synthesized via the reduction of phosphate with KBH 4 , the sharp diffraction peaks with high intensity and resolution indicate a high degree of crystallization.…”

Intracell Hydrogen Adsorption–Transmission in a Co2P Solid Hydrogen‐Storage Material

“…In the cyclic voltammogram shown in Figure (b), cathodic peaks at –1.10 and –1.00 V are due to the P–H bonding and Co ··· H interaction, respectively. Accordingly, anodic peaks at –0.92 and –0.70 V belong to the breaking of P–H bonds and the desorption of the hydrogen from the Co surface, respectively , . These redox peaks also provide evidence for the intracell Kubas‐enhanced hydrogen adsorption process in Co 2 P. In addition, it is found that the hydrogen‐storage capacity decreases at high rates of hydrogen charging/discharging, because the fast injection/extraction of hydrogen is disadvantageous to its spilling‐over process, as shown in Figure (c) and Table S3.…”
