Hydrogen Evolving(氢演变)研究综述
Hydrogen Evolving 氢演变 - Bubble behavior in a hydrogen evolving system was compared to that under boiling conditions. [1] Here, a series of hydrogen evolving photocatalysts based on a ruthenium(II) bipyridyl sensitiser covalently linked to Pt or Pd catalytic centres were adsorbed onto mesoporous NiO and tested for hydrogen evolution in a photoelectrochemical half-cell. [2] The hydrogen evolving activity of the materials was explored in pH 1. [3] The hydrogen evolving mechanism is discussed and the complexes are compared to their non-alkylated analogs using DFT calculations. [4] Under minimally optimized conditions, the resulting POM@MOF composites can effectively photocatalyze hydrogen production with superior long-term stability and reusability, achieving a hydrogen evolving rate of 3482 and 13051 μmol g−1 h−1 for Ni3PW10@NU-1000 and Ni3P2W16@NU-1000, respectively. [5] Benefitting from high density reactive sites and fluent mass transfer as a result of trimodal porous architecture and strong electronic modulation from NiZn intermetallic, TMP NiZn-Ni/NF primely overcomes the sluggish hydrogen evolving kinetics with superior catalytic performances comparable to Pt/C and many other reported similar electrocatalysts. [6] We have successfully integrated a covalently bonded hydrogen evolving catalyst (Complex A) into a highly stable photosensitizable UiO-MOF by a facile click reaction synthesis. [7] A facial cobalt(III) polypyridyl complex was characterized by several spectroscopic and electrochemical techniques and utilized as a robust hydrogen evolving catalyst in both organic and aqueous media. [8] 50 mA cm−2 owing to superior charge transport in hybrid photocathode as compared to pristine Si nanowires for hydrogen evolving reaction at pH∼7. [9] 1)-textured polycrystalline WSe2 films are developed as hydrogen evolving photoelectrodes and improved through deposition of a thin ammonium thiomolybdate (NH4)2Mo3S13 catalyst film. [10] The resulting ip-CoP/CF demonstrates improved hydrogen evolving efficiency in both acidic and alkaline conditions. [11] It is concluded that the water CHF condition can be simulated by the non-heating hydrogen evolving system. [12] Being one of the very few hydrogen evolving electrocatalytic MOFs based on a redox-active metallo-linker, this work explores uncharted terrain for greater catalyst diversity and charge transport pathways. [13]将析氢系统中的气泡行为与沸腾条件下的气泡行为进行了比较。 [1] 在这里，基于与 Pt 或 Pd 催化中心共价连接的钌 (II) 联吡啶敏化剂的一系列析氢光催化剂被吸附到介孔 NiO 上并在光电化学半电池中测试析氢。 [2] 在 pH 1 中探索了材料的析氢活性。 [3] 讨论了析氢机制，并使用 DFT 计算将配合物与其非烷基化类似物进行了比较。 [4] 在最小优化条件下，所得的 POM@MOF 复合材料可以有效地光催化制氢，具有优异的长期稳定性和可重复使用性，Ni3PW10@NU-1000 和 Ni3P2W16@ 的析氢速率分别为 3482 和 13051 μmol g-1 h-1 NU-1000，分别。 [5] 得益于三峰多孔结构和 NiZn 金属间化合物的强电子调制带来的高密度反应位点和流畅的传质，TMP NiZn-Ni/NF 以与 Pt/C 和许多其他催化剂相当的优异催化性能克服了缓慢的析氢动力学报道了类似的电催化剂。 [6] 我们通过简便的点击反应合成，成功地将共价键合的析氢催化剂（复合物 A）整合到高度稳定的光敏 UiO-MOF 中。 [7] 表面钴 (III) 多吡啶基配合物通过多种光谱和电化学技术进行了表征，并在有机和水性介质中用作稳健的析氢催化剂。 [8] 50mAcm-2 由于混合光电阴极中与原始 Si 纳米线相比在 pH ～ 7 的析氢反应中具有出色的电荷传输。 [9] 1) 纹理多晶 WSe2 薄膜被开发为析氢光电极，并通过沉积薄的硫代钼酸铵 (NH4)2Mo3S13 催化剂薄膜进行改进。 [10] 所得的 ip-CoP/CF 在酸性和碱性条件下均表现出改进的氢析出效率。 [11] 得出的结论是，非加热析氢系统可以模拟水的 CHF 条件。 [12] 作为极少数基于氧化还原活性金属连接剂的析氢电催化 MOF 之一，这项工作探索了未知领域，以实现更大的催化剂多样性和电荷传输途径。 [13]
