能源危机和环境恶化是现代人类社会面临的两大挑战。目前，化石燃料是人类使用的主要能源。化石燃料的燃烧产生能量，同时产生CO2和H2O。沿着全球能源消耗的急剧增长，地球上化石燃料资源的日益枯竭和大气中温室气体CO2的不断积累，引起了人们对能源和环境问题的关注。对这些问题的一石二鸟的解决方案可以是通过烷烃逆燃烧反应将CO2转化为碳氢化合物（方程式11）。(1))以太阳能作为能量输入。整个过程让人想起光合作用，导致CO2和H2O净转化为碳水化合物和O2，以及光能转化为化学能。近年来，用于燃料和化学品生产的人工光合系统经历了快速增长[1]。ð3n ð1 H2O！3n CnH2nH2O CnH2nH2O CnCO2！CnH2nH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2NH2
Energy crisis and environmental degradation are the two most server challenges to modern humane society. Currently, fossil fuels are the main energy resource used by human-beings. The combustion of fossil fuels generates energy and at the same time produces CO2 and H2O. Along with the world’s soaring energy consumption, the depleting of fossil fuel resources on earth and the accumulation of the greenhouse gas, CO2, in atmosphere have raised people’s concerns on the related energy and environment issues. A one-stone-two-birds solution to these problems could be converting CO2 into hydrocarbons via the alkane reverse combustion reaction (Eq.(1)) with solar energy as the energy input. The whole process is reminiscent to photosynthesis that leads to the net conversion of CO2 and H2O into carbohydrates and O2, and the conversion of light energy into chemical energy. In the recent years, artificial photosynthetic systems for fuel and chemical production have experienced rapid growth [1]. ð3n þ 1ÞH2O! ð3n þ 1Þ/2O2 þ ð6n þ 2ÞHþ þ ð6n þ 2ÞeÀ nCO2 þ ð6n þ 2ÞHþ þ ð6n þ 2ÞeÀ!
