现代文明依赖于化石燃料,这是一种最初由太阳能储存提供的不可再生能源。对化石燃料的依赖带来了严重的后果,包括能源安全问题和温室气体排放。依赖化石燃料的后果可以通过模仿自然光合作用的燃料生产人工系统来避免,直接将太阳能转化为燃料。本文综述了光合作用中太阳能转换的三个关键组成部分:光收集、电荷分离和催化。这些过程在自然和人工系统中进行了比较。这种比较有助于理解光合作用的一般原理,并有助于开发包括用于太阳能转换的光电化学电池在内的工作装置。
Modern civilization is dependent upon fossil fuels, a nonrenewable energy source originally provided by the storage of solar energy. Fossil fuel dependence has severe consequences including energy security issues and greenhouse gas emissions. The consequences of fossil fuel dependence could be avoided by fuel-producing artificial systems that mimic natural photosynthesis, directly converting solar energy to fuel. This review describes the three key components of solar energy conversion in photosynthesis: light harvesting, charge separation, and catalysis. These processes are compared in natural and artificial systems. Such a comparison can assist in understanding the general principles of photosynthesis and in developing working devices including photoelectrochemical cells for solar energy conversion.
