| 中文摘要 | 仍需要設計一個有利的催化劑來增強 NaBH4 水解中氫氣 (H2) 的釋放。在此，使用長方體鈷基金屬有機框架（Co-MOF）作為模板，透過簡單的雕刻和煅燒構建了空隙工程的毛茸茸的氧化鈷（VSCO）。所製備的 VSCO 顯示出獨特的結構特性，如大的內部空隙、高比表面積和豐富的氧空位，使 VSCO 能夠提高 NaBH4 水解產生的 H2 產量。VSCO 也表現出 28.9 kJ mol−1 的活化能 (Ea)，遠低於商業 Co3O4 NP (62.9 kJ mol−1) 和大多數最近報告的貴金屬。VSCO 在多個循環中也保持其優異的催化活性。這項工作揭示了建構具有空隙結構和豐富氧空位的金屬氧化物材料用於催化 NaBH4 水解的新方法。 |
| 英文摘要 | Designing an advantageous catalyst for enhancing the release of hydrogen (H2) from NaBH4 hydrolysis is still desirable. Herein, a void-engineered shaggy cobalt oxide (VSCO) is constructed via facile carving and calcination using the cuboid cobalt-based metal organic framework (Co-MOF) as a template. The as-prepared VSCO shows unique structural properties, such as large internal void, high specific surface area, and abundant oxygen vacancy, enabling VSCO to boost H2 production from NaBH4 hydrolysis. VSCO also exhibits an activation energy (Ea) of 28.9 kJ mol−1, which is much lower than that of commercial Co3O4 NP (62.9 kJ mol−1) and most of recent reported noble metals. VSCO also retains its outstanding catalytic activity over multiple cycles. This work sheds a light into the new approach of constructing metal oxide material with the void structure and abundant oxygen vacancies for catalyzing the hydrolysis of NaBH4. |
