提示词：Please generate a high-quality scientific mechanism schematic diagram for academic publication, with a style similar to the charts in journals like "Nature Communications" or "Advanced Materials," requiring a modern, concise style with clear information. Core theme: Demonstrate the "spatial decoupling" purification mechanism of a W₁₈O₄₉ nanowire-coated tourmaline core-shell structure photocatalyst used for purifying enclosed water bodies (such as fish tanks). Image content and element requirements: Overall layout: Use a central cross-sectional view to showcase a complete core-shell structured catalyst particle. Core layer (center): Label as "Tourmaline core," and indicate its key feature next to it with illustrations and text: "spontaneous polarization electric field," visually represented by abstract electric field lines. Shell layer (outer): Label as "W₁₈O₄₉ nanowire (shell)," and indicate its key feature next to it with illustrations and text: "rich in oxygen vacancies," which can be represented by symbols of some point defects. Process and path display (clearly show the following dynamic processes with arrows of different colors and labels): Pollutant adsorption path: Use blue arrows to represent the process of "pollutant molecules (e.g., RhB)" migrating from the external water body to the surface of the W₁₈O₄₉ shell layer and being adsorbed and enriched. Oxygen/water transport path: Use green arrows to indicate the directional transport of "O₂ molecules" and "H₂O molecules" through the nanoscale channels of the W₁₈O₄₉ shell to the interface between the tourmaline core and the W₁₈O₄₉ shell. Active species generation and diffusion: At the core-shell interface, due to light excitation and the electric field effect of tourmaline, O₂ and H₂O are activated, producing highly active "hydroxyl radicals (·OH)." Represent the generation of ·OH with explosive red star points and use red radial arrows to indicate their reverse diffusion from the generation point to the surface of the shell. Pollutant degradation: At the shell surface, red ·OH encounters blue pollutant molecules, and the pollutant molecules are "broken down" into harmless "CO₂ + H₂O" small molecules, indicated by broken patterns and labeled final products. Background and environment: Draw a light blue water background around the catalyst particle, with a few bubbles to suggest a fish tank water environment. From the top of the image, a yellow beam representing "light irradiation" shines down towards the catalyst. Caption and title area: Reserve space at the bottom or side of the image to add a title, such as "Core-Shell Catalyst 'Adsorption-Transport-Activation-Degradation' Spatial Decoupling Mechanism Diagram," along with legends explaining each part. Style requirements: Vector flat style or slightly textured 3D style, distinct colors, a sense of technology, clear lines, and readable labeling fonts. --ar 1:1 --v 7 --stylize 100

中文提示词：请生成一张用于学术发表的、高质量的科学机理示意图，风格类似《Nature Communications》或《Advanced Materials》期刊的图表风格，要求风格现代、简洁、信息清晰。 核心主题： 展示一种用于封闭水体（如鱼缸）净化的W₁₈O₄₉纳米线包覆电气石核壳结构光芬顿催化剂的“空间解耦”净化机理。 图片内容与元素要求： 整体布局： 采用中心剖面图的形式，展示一个完整的核壳结构催化剂颗粒。 核层（中心）： 标注为“电气石（Tourmaline）核”，并在一旁用图示和文字注明其关键特性：“自发极化电场”，用抽象的电场线来直观表示。 壳层（外部）： 标注为“W₁₈O₄₉纳米线（壳层）”，并在一旁用图示和文字注明其关键特性：“富含氧空位”，可以用一些点缺陷的符号来表示。 过程与路径展示（用不同颜色的箭头和标注清晰地展示以下动态过程）： 污染物吸附路径： 用蓝色箭头表示水体中的“污染物分子（如RhB）”从外部水体向W₁₈O₄₉壳层表面迁移并被吸附、富集的过程。 氧气/水传输路径： 用绿色箭头表示“O₂分子”和“H₂O分子”通过W₁₈O₄₉壳层的纳米通道，被定向输送至电气石核与W₁₈O₄₉壳的界面。 活性物种生成与扩散： 在核壳界面处，由于光激发和电气石的电场作用，O₂和H₂O被活化，产生高活性的“羟基自由基（·OH）”。用爆炸状的红色星点表示·OH的生成，并用红色的放射状箭头表示它们从生成点反向扩散至壳层表面。 污染物降解： 在壳层表面，红色的·OH与蓝色的污染物分子相遇，污染物分子被“打碎”成无害的“CO₂ + H₂O”小分子，用破碎的图案和最终产物标注来示意。 背景与环境： 在催化剂颗粒周围，绘制淡蓝色的水背景，并点缀少量气泡，暗示鱼缸水体环境。 从画面上方照射下代表“光照射”的黄色光束，指向催化剂。 图注与标题区： 在图片底部或侧面预留空间，用于添加标题，如“核壳催化剂‘吸附-传输-活化-降解’空间解耦机理图”，以及对各部分进行解释的图例。 风格要求： 矢量扁平风或微质感立体风，色彩分明，有科技感，线条清晰，标注字体清晰易读。 一键画同款
