Prompt Description
Graphical Abstract Abstract Due to the high toxicity and low degradability of phenolic compounds, including hydroquinone (HQ), in environmental samples, there is a strong need for the development of efficient catalytic systems for the oxidation of hydroquinone to benzoquinone (BQ). Catalytic oxidation using nanoscale metal-based catalysts has been recognized as an effective approach for the removal of such contaminants. In this study, reduced graphene oxide-based iron oxide, iron nitride, and cobalt ferrite nanocomposites were synthesized using co-precipitation, pyrolysis, and hydrothermal methods. The obtained nanocomposites were characterized by UV–Vis spectroscopy, X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area analysis, and field-emission scanning electron microscopy (FESEM). The catalytic performances of the synthesized nanocomposites toward the oxidation of hydroquinone to benzoquinone using H₂O₂ in aqueous solution were comparatively evaluated. The results

### I. Core Design Concept
Use a **"left-to-right" visual narrative flow** to summarize the entire study: **Molecular Design → Interfacial Assembly → Functional Application**. Ensure the graphic is clearly discernible in a single-column width.
### II. Suggested Composition (Three-Part Layout)
**Part 1 (Left): Molecular Structure and Design**
* **Visual Elements**:
1. Draw a simplified model of **β-cyclodextrin (β-CD)** (like a truncated cone or cylinder, using lines to represent glucose units).
2. Within the cavity of β-CD, embed a simplified model of the **imidazolium cation ([Bmim]⁺)**, highlighting the butyl chain extending into the cavity, using **dashed lines** or a **glowing effect** to illustrate the **host-guest inclusion interaction**.
3. From one end of β-CD, extend a **wavy line** representing the **PEG chain**, and label it "PEG" or "CO₂-philic" at the end.
4. Draw a simplified structural formula of the **BCA molecule** next to it, and use an **arrow** pointing to β-CD to indicate that it is included as a "guest."
5. Near the PEG chain or on BCA, schematically add the functional group symbols for **thiol (-SH)** and **acrylate (C=C)**, laying the groundwork for dynamic crosslinking.

**Part 2 (Middle): Interfacial Assembly and Reinforcement**
* **Visual Elements**:
1. Draw a clear **interface**, with the upper part using a light blue background and CO₂ molecule models (•) to represent the **scCO₂ phase**, and the lower part using a light green or yellow background to represent the **ionic liquid (IL) phase**.
2. At the interface, arrange multiple **β-CD-PEG molecules from Part 1**, with their β-CD heads immersed in the IL phase (including [Bmim]⁺) and their PEG tails extending into the scCO₂ phase.
3. Crucially: between these arranged molecules, draw a **network structure of covalent bonds** (which can be achieved by connecting thiol and acrylate sites with short chains), forming a **"crosslinked network"** covering the interface.
4. Label the network with ***G′ > G″*** or **Elastic Film**](/_next/image?url=https%3A%2F%2Fpub-8c0ddfa5c0454d40822bc9944fe6f303.r2.dev%2Fai-drawings%2F3K0lbJphG6f45jPmN5kawgbmjHkzigDR%2F2d81a213-a821-44f0-b803-e296ace80e9c%2F5e212834-e3b9-4931-9b2c-476f3f7f4ded.png&w=3840&q=75)
