Abstract

Amid growing global energy demands and environmental concerns, hydrogen energy has emerged as a promising clean alternative. This study focuses on the development of efficient photoelectrocatalytic materials for the oxygen evolution reaction (OER). Three novel two-dimensional coordination polymers—SNUT-9-Cd, SNUT-9-Cd+Co, and SNUT-9-Co—were solvothermally synthesized using a tricarboxylic pyridazine-based ligand, H₃(5-CMOIA). Thermogravimetric analysis (TGA) confirmed their high thermal stability, with SNUT-9-Co maintaining structural integrity up to 300°C. Mott–Schottky analysis confirmed the n-type semiconductor behavior of all three compounds. SNUT-9-Co stood out with its superior OER performance under simulated solar irradiation, displaying a low overpotential of 261 mV at 0.3 mA·cm⁻², rapid charge transfer, and excellent stability, thereby highlighting its promise as a photoanode for solar-driven water splitting.

二维配位聚合物作为太阳能驱动水氧化的高效光阳极

在日益增长的全球能源需求和对环境的担忧中，氢能源已成为一种有前途的清洁能源。本研究的重点是开发出出氧反应（OER）的高效光电催化材料。采用三羧基吡啶配体H3（5-CMOIA）溶剂热合成了3种新型二维配位聚合物- SNUT-9-Cd、SNUT-9-Cd+Co和snut -9-Co。热重分析（TGA）证实了它们的高热稳定性，SNUT-9-Co在300°C下保持结构完整性。莫特-肖特基分析证实了这三种化合物的n型半导体行为。SNUT-9-Co在模拟太阳照射下表现出优异的OER性能，在0.3 mA·cm−2下表现出261 mV的低过电位，快速的电荷转移和优异的稳定性，从而突出了其作为太阳能驱动水分解的光阳极的前景。

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
