A solvent-free sulfur-bridge-eosin-Y (SBE-Y) polymeric framework photocatalyst was prepared for the first time through an in situ thermal polymerization route using elemental sulfur (S₈) as a bridge. The addition of a sulfur bridge to the polymeric framework structure resulted in an allowance of the harvesting range of eosin-Y (E-Y) for solar light. This shows that a wider range of solar light can be used by the bridge material's photocatalytic reactions. In this context, supercharged solar spectrum: enhancing light absorption and hole oxidation with sulfur bridges. This suggests that the excited electrons and holes through solar light can contribute to oxidation–reduction reactions more potently. As a result, the photocatalyst-enzyme attached artificial photosynthesis system developed using SBE-Y as a photocatalyst performs exceptionally well, resulting in high 1,4-NADH regeneration (86.81%), followed by its utilization in the exclusive production of formic acid (210.01 μmol) from CO₂ and synthesis of fine chemicals with 99.9% conversion yields. The creation of more effective photocatalytic materials for environmental clean-up and other applications that depend on the solar light-driven absorption spectrum of inorganic and organic molecules could be one of the practical ramifications of this research.

彻底改变碳化学：通过新设计的 SBE-Y 尖端动态光催化剂进行太阳能驱动的 C(sp3)–N 键活化和 CO2 转化

首次使用元素硫 (S) 通过原位热聚合途径制备了无溶剂硫桥伊红-Y (SBE-Y) 聚合物骨架光催化剂₈）作为桥梁。在聚合物框架结构中添加硫桥导致了曙红-Y (E-Y) 的太阳光捕获范围的允许。这表明桥材料的光催化反应可以利用更广泛的太阳光。在这种背景下，增压太阳光谱：通过硫桥增强光吸收和空穴氧化。这表明通过太阳光激发的电子和空穴可以更有效地促进氧化还原反应。结果，使用SBE-Y作为光催化剂开发的光催化剂-酶附着人工光合作用系统表现异常良好，导致1,4-NADH高再生率（86.81％），随后将其用于甲酸的独家生产（ 210.01 μmol)从CO₂合成精细化学品，转化率99.9%。为环境净化和其他依赖于太阳光驱动的无机和有机分子吸收光谱的应用创造更有效的光催化材料可能是这项研究的实际后果之一。
