大规模复制自然光合作用过程是储存太阳能和保护环境的重要课题。在这里，我们报道了飞秒激光诱导自组装金属纳米结构阵列，它很容易在地球上丰富的金属上大规模生产，可以直接从二氧化碳、水和阳光合成液体和固体碳氢化合物，其生产率超过 1 X 10(5) mu L/(gh)，显着高于以前的研究（10(3)-10(6) 倍）。(1,2) 光合作用储存太阳能的效率为目前简单的实验设置大约占 10%，还可以进一步改进。此外，与以往的人工光合作用工作不同，这种现象提出了一种新的机制，通过表面增强的光解离过程，可以人工进行类似自然的光合作用。
Large-scale replication of the natural process of photosynthesis is a crucial subject of storing solar energy and saving our environment. Here, we report femtosecond laser induced self-assembled metal nanostructure arrays, which are easily mass producible on earth-abundant metals, can directly synthesize liquid and solid hydrocarbon compounds from carbondioxide, water, and sunlight at a production rate of more than 1 X 10(5) mu L/(gh) that is significantly (10(3)-10(6) times) higher than those in previous studies.(1,2) The efficiency for storing solar energy of the photosynthesis is about 10% in the present simple experimental setup which can be further improved. Moreover, different from previous artificial photosynthesis works, this phenomenon presents a new mechanism that, through a surface-enhanced photodissociation process, nature-like photosynthesis can be performed artificially.
