The past several decades have seen a significant rise in atmospheric carbon dioxide levels resulting from the combustion of hydrocarbon fuels. A solar energy based technology to recycle carbon dioxide into readily transportable hydrocarbon fuel (i.e., a solar fuel) would help reduce atmospheric CO2 levels and partly fulfill energy demands within the present hydrocarbon based fuel infrastructure. We review the present status of carbon dioxide conversion techniques, with particular attention to a recently developed photocatalytic process to convert carbon dioxide and water vapor into hydrocarbon fuels using sunlight.
过去几十年，由于碳氢燃料的燃烧，大气中二氧化碳的含量显著上升。利用太阳能将二氧化碳转化为易于运输的碳氢燃料（即太阳能燃料）的技术将有助于降低大气中二氧化碳的含量，并在一定程度上满足当前碳氢燃料基础设施的能源需求。我们回顾了二氧化碳转化技术的现状，特别关注最近开发的一种光催化工艺，该工艺利用阳光将二氧化碳和水蒸气转化为碳氢燃料。
