Abstract

A FeOCl derivative is prepared in water using pyrrole (apy-FeOOH). The X-ray diffraction pattern of the product is similar to γ-FeOOH. From chemical analyses and the FT-IR spectrum, it is found that pyrrole remains in the product with an atomic ratio of Fe:N = 3:1. From discharge/charge cycling tests, it is confirmed that apy-FeOOH is rechargeable and has a specific capacity of 60 mAh g-1 between 2.0 and 4.5 V on the 20th discharge. When N-methylpyrrole (which has similar structure) is used instead of pyrrole, the derivative yields larger capacity during ten cycles.
