rw-02: Paper Paragraph Writing — Cu Vacancy Results

任务信息

• 模块： research-writing
• 学科： Chemistry
• 深度： L2
• 判定： PASS

输入

Experimental data table: Cu2O nanocubes with 0-7.8% Cu vacancies, electrochemical NO3RR performance (FE, yield, selectivity vs potential), 12-h stability test, supporting DFT results (DeltaG for NO3, H, PDS).

输出

~280-word Results subsection demonstrating:

• Clear volcano-type dependence: FE peaks at 87.2% (4.3% V_Cu), 52% yield improvement over pristine
• Three-way correlation: EPR vacancy → electrochemical FE → DFT DeltaG
• HER suppression mechanism: DeltaG(*H) shift -0.19→+0.06 eV matches experimental H2 FE decline (15.3→7.7%)
• Honest stability reporting: FE decline (87.2→78.5%, 12h) attributed to partial vacancy healing (4.3→2.8% by EPR)
• No AI-template phrases; 9 specific numeric values cited; appropriate hedging ("suggests", "consistent with")

判定

PASS — publication-ready subsection draft with high evidence density and honest limitations.
