The field of sustainable heterogeneous catalysis is evolving rapidly, with a strong emphasis on developing catalysts that enhance efficiency. Among various heterogeneous photocatalysts, metal-organic frameworks (MOFs) have gained significant attention for their exceptional performance in photocatalytic reactions. In this context, contrary to the conventional homogeneous iridium or ruthenium-based photocatalysts, which face significant challenges in terms of availability, cost, scalability, and recyclability, a new Ba/Ti MOF (ACM-4) is developed as a heterogeneous catalyst that can mimic/outperform the conventional photocatalysts, offering a more sustainable solution for efficient chemical processes. Its redox potential and triplet energy are comparable to or higher than the conventional catalysts, organic dyes, and metal semiconductors, enabling its use in both electron transfer and energy transfer applications. It facilitates a broad range of coupling reactions involving pharmaceuticals, agrochemicals, and natural products, and is compatible with various transition metals such as nickel, copper, cobalt, and palladium as co-catalysts. The effectiveness of the ACM-4 as a photocatalyst is supported by comprehensive material studies, photophysical, and recycling experiments. These significant findings underscore the potential of ACM-4 as a highly versatile and cost-effective photoredox catalyst, providing a sustainable, one-material solution for efficient chemical processes.
可持续多相催化领域正在迅速发展，重点是开发提高效率的催化剂。在各种多相光催化剂中，金属有机框架（MOF）因其在光催化反应中的卓越性能而备受关注。在这种情况下，与传统的均相铱或钌基光催化剂不同，后者在可用性、成本、可扩展性和可回收性方面面临重大挑战，一种新型的Ba/Ti MOF（ACM-4）被开发为一种多相催化剂，它可以模仿/超越传统光催化剂，为高效化学过程提供更可持续的解决方案。其氧化还原电位和三线态能量与传统催化剂、有机染料和金属半导体相当或更高，使其能够用于电子转移和能量转移应用。它促进了涉及药物、农用化学品和天然产物的广泛偶联反应，并且与镍、铜、钴和钯等各种过渡金属作为共催化剂兼容。ACM-4作为光催化剂的有效性得到了全面的材料研究、光物理和回收实验的支持。这些重要发现强调了ACM-4作为一种高度通用且具有成本效益的光氧化还原催化剂的潜力，为高效化学过程提供了一种可持续的单一材料解决方案。
