The integration of molecular photosensitizers and catalysts into functional soft matter supports holds great promise for future energy conversion technologies. Herein, we report the electrostatic immobilization of the molecular molybdenum sulfide hydrogen evolution reaction catalyst [Mo₃S₁₃]²⁻ and the photosensitizer [Ru(bpy)₃]²⁺ on the surface of nanoporous block copolymer membranes. The resulting hybrid materials show sustained visible light-driven hydrogen evolution in acidic media, even at low photosensitizer loadings. Initial mechanistic studies highlight the stability and development challenges for this new composite materials class. The study therefore represents a major advance for the integration of molecular catalysts into nanostructured soft matter matrices.

将分子光敏剂和催化剂嵌入纳米多孔嵌段共聚物膜中，以产生可见光驱动的氢气逸出

将分子光敏剂和催化剂整合到功能性软物质载体中，对于未来的能量转换技术具有广阔的前景。在此，我们报告了分子硫化钼氢释放反应催化剂[Mo ₃ S ₁₃ ] ^2-和光敏剂[Ru（bpy）₃ ] ²⁺的静电固定化。在纳米多孔嵌段共聚物膜的表面上。所得的杂化材料即使在低光敏剂负载下，也能在酸性介质中持续产生可见光驱动的氢释放。初步的力学研究突显了这种新型复合材料类别的稳定性和开发挑战。因此，这项研究代表了将分子催化剂集成到纳米结构软物质基质中的重大进展。
