中国科学院大连化学物理研究所李灿团队研发出一种仿生空心纳米反应器,能够在可见光照射下高效地将阳光转化为过氧化氢。[1]
这种名为CdS@多巴胺的纳米反应器模拟了活细胞的两项关键特性——质子中继系统和分隔空心结构,使其在光催化合成过氧化氢方面表现出色。[1]根据研究数据,该纳米反应器实现了3.24 mmol/gcat·h的过氧化氢光合速率和1.2%的太阳能-化学能转换效率。[1]
该纳米反应器可以嵌入可回收的海藻酸钠水凝胶基质中实现连续工作。[1]这项研究由李灿教授领导,与内蒙古大学刘健团队合作完成,成果已发表于《美国化学会志》。[1]
Researchers at the Dalian Institute of Chemical Physics have developed a biomimetic hollow nanostructure reactor that harnesses visible light to efficiently produce hydrogen peroxide, mimicking two critical functions found in living cells [1]. The CdS@dopamine nanoreactor achieves a hydrogen peroxide photosynthetic rate of 3.24 mmol per gram of catalyst per hour and demonstrates a solar-to-chemical energy conversion efficiency of 1.2% [1]. Led by Professor Li Can in collaboration with a team from Inner Mongolia University headed by Liu Jian, the innovation integrates a proton relay system and compartmentalized hollow structure to replicate cellular mechanisms [1].
The nanostructure can be embedded within recyclable sodium alginate hydrogel matrices, enabling continuous operation in practical applications [1]. The research, published in the Journal of the American Chemical Society, represents a significant advance in photocatalytic synthesis powered by renewable solar energy [1].
