Abstract
For the purpose of energy conversion from the hydrogen oxidation reaction (HOR) and oxygen reduction reaction (ORR), never-before synthesized platinum-cobalt nanowires grown on activated carbon were applied to a rotating ring-disk dual-electrode (RRDE) to study their performance, efficiency, and kinetics toward the ORR compared to a benchmark commercial catalyst.Also, majority {010} facet growth-directed lithium iron phosphate (LFP) was produced by a solvothermal synthesis via capping agents to host short lithium diffusion distances in lithium ion battery (LIB) cathodes for increased specific capacity at high power rates. The ultrathin nanosheets produced were characterized by SEM, TEM, AFM, XRD, Raman spectroscopy, and electrochemically tested by cycling them between two voltage thresholds. Further, multiple carbon-addition techniques were employed to enhance conductivity and charge transfer to the nanosheet active material. These ultrathin, micron-sized nanosheets synthesized from a bottom-up approach, yielding the thinnest to date, 12 nm profile in the direction of lithium diffusion.
