在这一观点中，我们讨论了目前人工光合作用研究中的挑战，重点是纳米线形态的好处。匹配电催化剂与光吸收剂之间的通量，以及单个半导体光吸收剂之间的通量，是设计经济上可行的人工光合作用装置的两个主要问题。认识到自然光合作用是一个完整的纳米系统，讨论了仿生人工光合作用的各个组成部分。在集成设备设计方案下提出了可能的研究方向，并举例说明了我们在这些领域的当前进展。将包括电催化剂、光吸收剂和电荷传输单元在内的所有组件耦合在一起，从基础和实际考虑都是至关重要的。考虑到一维纳米结构的优势，半导体纳米线显然可以作为基本的构建模块，帮助解决人工光合作用中的许多问题。
In this Perspective, we discuss current challenges in artificial photosynthesis research, with a focus on the benefits of a nanowire morphology. Matching the flux between electrocatalysts and light-absorbers, and between individual semiconducting light-absorbers, are two major issues to design economically viable devices for artificial photosynthesis. With the knowledge that natural photosynthesis is an integrated nanosystem, individual building blocks of biomimetic artificial photosynthesis are discussed. Possible research directions are presented under an integrated device design scheme, with examples of our current progress in these areas. Coupling all of the components together, including electrocatalysts, light-absorbers, and charge transport units, is crucial due to both fundamental and practical considerations. Given the advantages of one-dimensional nanostructures, it is evident that semiconductor nanowires can function as essential building blocks and help to solve many of the issues in artificial photosynthesis.
