提示词:https://images.gogpt.vip/aigf/m_origin/20250709/1693334/0wk5qim0gavr47fz.png This is a schematic design comparing two synthesis processes, highlighting the morphological differences of reactants, key additives, and final products. Hydrothermal synthesis comparison schematic: Bismuth iodide (BiOI) vs Submicron bismuth powder (Bi⁰) Left pathway (Pathway A- Synthesis of BiOI): Initial reactants: Clearly list deionized water, bismuth nitrate (Bi³⁺ source), potassium iodide (I⁻ source), mannitol (morphology controlling agent/complexing agent). Mixed solution: Label the main ions/molecules in the solution (Bi³⁺, I⁻, mannitol). Hydrothermal reaction: Represented by a box, label typical conditions (temperature T °C, time t hours). Next to the arrow, note the main reaction: Bi³⁺ combines with I⁻ to form BiOI. Note that mannitol's role is to assist in morphology control. Final product: BiOI. Use simple layered stacking graphics to illustrate its typical flaky or flower-like micro-nano structure. Right pathway (Pathway B- Synthesis of Bi⁰): Initial reactants: Contains all reactants from Pathway A, with the addition of sodium hypophosphite (NaH₂PO₂, strong reducing agent, providing H₂PO₂⁻). Mixed solution: Label the main ions/molecules in the solution (Bi³⁺, I⁻, mannitol, H₂PO₂⁻). Hydrothermal reaction: The box conditions are the same as on the left side (emphasizing that it is under the same hydrothermal environment, only the additives are different). Next to the arrow, note the key reaction: H₂PO₂⁻ reduces Bi³⁺ to elemental bismuth (Bi⁰). Similarly, note the morphology control role of mannitol. Final product: Submicron bismuth powder (Bi⁰). Use dispersed small spheres or irregular particle graphics to illustrate its submicron scale metallic powder morphology.
