Trimethylamine sensing properties of graphene quantum Dots/α-Fe2O3 composites

α‐Fe2O3 Polyhedral Nanoparticles Enclosed by Different Crystal Facets: Tunable Synthesis, Formation Mechanism Analysis, and Facets‐dependent n‐Butanol Sensing Properties

“…On the other hand, the theoretical angle between {104} planes family is 64.9°, in good agreement with that measured by SEM image (inset of Figure a) and TEM image (Figure a). Combining with the inner angle of the perfect rhombuses observed in the SEM and TEM images, the rhomboidal particles were confirmed to be bounded by six equivalent {104} planes, which was in good agreement with the previous reports …”

Seaweed‐derived polymer‐based blue‐emitting C‐dots: synthesis, characterization and evaluation for iron sensing

“…CMA shows ca 70% weight loss while the weight loss of C‐dots was ca 30% up to 500 °C. The initial weight loss was due to the loss of moisture and water formed from the condensation of the hydroxyl groups present on the C‐dot surface 41 . The second weight loss step was due to loss of CO 2 generated from the decarboxylation of (–COO − ) groups in this temperature range.…”

A corn-inspired structure design for an iron oxide fiber/reduced graphene oxide composite as a high-performance anode material for Li-ion batteries

“…It is obvious that the surface of Fe 2 O 3 /rGO composites has a smooth lm, which indicates Fe 2 O 3 was coated in the rGO sheets. This phenomenon can be explained as follows: the oxygen-containing functional groups (hydroxyl, carbonyl and carboxyl groups) on the GO make it negatively-charged and they can act as anchor sites that interact strongly with the covered species; 39 when treating the mix solution of negatively charged GO and positively charged Fe 2 O 3 bers with ultrasound, the positively-charged Fe 2 O 3 ber may be absorbed on the negatively-charged surface of GO, which may promote the coating of Fe 2 O 3 bers by GO. A regular diffraction spot ring is observed from the selected-area electron diffraction (SAED) pattern ( Fig.…”
