开发了一种低温回流方法来合成大量分散良好的独立式 ZnO 纳米棒，从而能够通过固态 H1 魔角自旋核磁共振 (NMR) 光谱直接观察和表征氢。与 ZnO 纳米/微米颗粒相比，加热至 500°C 的 ZnO 纳米棒中保持了令人惊讶的尖锐 H1 NMR 共振，这表明存在异常稳定的氢。定量 H1 NMR 测量表明，以摩尔计，约 0.1% 的这些氢物质存在于 ZnO 纳米棒的晶格中。这项工作证明 H1 NMR 是探测 ZnO 纳米棒中氢的强大技术。
A low-temperature reflux method was developed to synthesize large quantities of well-dispersed freestanding ZnO nanorods, which enabled the direct observation and characterization of hydrogen by solid-state H1 magic angle spinning nuclear magnetic resonance (NMR) spectroscopy. In contrast to nano/micrometer particles of ZnO, a surprisingly sharp H1 NMR resonance was maintained in ZnO nanorods that were heated to 500°C, suggesting the existence of unusually stable hydrogen. Quantitative H1 NMR measurements indicate that about 0.1% on a molar basis of these hydrogen species resides in the lattice of ZnO nanorods. This work has demonstrated that H1 NMR is a powerful technique for probing hydrogen in ZnO nanorods.
