Morphological and structural analysis of the Fe(OH)3 and CuS transitions to Fe2O3 and CuO

Flower‐like Fe(OH)3 as Sulfur Hosts for High‐Performance Lithium–Sulfur Batteries

“…Fe(OH) 3 gradually decomposes with the increase in temperature; when the temperature reaches 500 °C, the Fe(OH) 3 completely decomposes into α-Fe 2 O 3 with a total weight loss of about 10.2 %. [38][39][40] In the S@FH composites sample, the material weight loss comprises the evaporation of sulfur and the decomposition of Fe(OH) 3 . Considering the weight loss of S@FH composites (61.9 %) and the established ratio (60 : 40) between sulfur and Fe(OH) 3 within the composites, it can be inferred that the final sulfur content of the S@FH composites is 57.82 %, (61.9 %À (10.2 %×40 %) = 57.82 %).…”

“…The curve for sulfur shows that the weight loss temperature ranges from 242 °C to 381 °C. Fe(OH) 3 gradually decomposes with the increase in temperature; when the temperature reaches 500 °C, the Fe(OH) 3 completely decomposes into α‐Fe 2 O 3 with a total weight loss of about 10.2 % [38–40] . In the S@FH composites sample, the material weight loss comprises the evaporation of sulfur and the decomposition of Fe(OH) 3 .…”
