虽然化石燃料中的化学能使现代文明迅速崛起，但其利用和伴随的人为二氧化碳排放正在以超过自然碳循环的速度发生。它的影响现在被认为是不可逆转的，这可能导致人类社会的灭亡。这是一个复杂的问题，没有一个单一的解决方案，但从全球在二氧化碳捕获和利用领域蓬勃发展的研究活动和发展来看，隧道尽头有光。在这篇文章中，一对夫妇的最新进展进行了说明。注意力集中在发现气相，光辅助的多相催化材料和CO2光还原过程中，在足够高的速率和转换效率，并在温和的条件下，打开一个新的途径，从今天的能源过渡“化石燃料经济”到一个新的和可持续的“CO2经济”。无论哪种相互竞争的CO2捕获和利用方法被证明是发展未来基于CO2的太阳能燃料经济的最佳途径，希望这能够在足够短的时间内发生，以避免温室气体气候变化的预测不利后果。
While the chemical energy in fossil fuels has enabled the rapid rise of modern civilization, their utilization and accompanying anthropogenic CO2 emissions is occurring at a rate that is outpacing nature's carbon cycle. Its effect is now considered to be irreversible and this could lead to the demise of human society. This is a complex issue without a single solution, yet from the burgeoning global research activity and development in the field of CO2 capture and utilization, there is light at the end of the tunnel. In this article a couple of recent advances are illuminated. Attention is focused on the discovery of gas-phase, light-assisted heterogeneous catalytic materials and processes for CO2 photoreduction that operate at sufficiently high rates and conversion efficiencies, and under mild conditions, to open a new pathway for an energy transition from today's "fossil fuel economy" to a new and sustainable "CO2 economy". Whichever of the competing CO2 capture and utilization approaches proves to be the best way forward for the development of a future CO2-based solar fuels economy, hopefully this can occur in a period short enough to circumvent the predicted adverse consequences of greenhouse gas climate change.
