利用太阳能作为能量来源,将CO2和H2O直接转化为化学燃料,既可降低大气中的CO2浓度,又能将太阳能转变为易于储存与运输的化学燃料,对低碳减排以及太阳能利用均具有重要意义.其中太阳能光热化学转化方式可以利用整个太阳能能谱,理论上具有较高的能量转换效率,逐渐受到国际社会的关注.本文简要综述近年来这一研究领域的一些重要进展,总结本课题组在热化学法分解CO2和H2O方面取得的最新结果,对太阳能光热化学转化CO2和H2O的未来发展进行展望.
The use of solar energy as a source of energy and the direct conversion of CO2 and H2O into chemical fuels can both reduce CO2 concentrations in the atmosphere and convert solar energy into chemical fuels that are easy to store and transport and are important for both low carbon emissions and solar energy utilization Significance.Among them solar solar thermal chemical conversion can take advantage of the entire solar energy spectrum, in theory, has a high energy conversion efficiency, gradually by the international community’s attention.This article briefly reviews some important progress in recent years in this area of research, summarizes the subject The latest results achieved by the group of thermochemical methods for the decomposition of CO2 and H2O are expected to predict the future development of solar photothermal chemical conversion of CO2 and H2O.
