The sufficient supply of energy remains one of the most important challenges for a sustainable development of our society. In this respect, capturing sunlight energy by photocatalytic reduction of the greenhouse gas CO2 is interesting. In a more general way, the smart use of CO2 as C1-feedstock and its conversion to valuable carbon-based materials and energy sources can be the basis to establish a closed-CO2 cycle. This review summarizes recent advances in photocatalytic utilization of CO2 catalyzed by most prominent TiO2 based systems. The influences of different structures (i.e. crystal phase, morphology, vacancies, and defects), co-catalysts, and reaction conditions onto the catalyst performance are specifically highlighted. Furthermore, the reader attention is drawn to the oxidation counter reaction, which has been often neglected in the past.

TiO 2基光催化CO 2还原的最新进展
充足的能源供应仍然是我们社会可持续发展的最重要挑战之一。在这方面,通过光催化还原温室气体CO 2捕获阳光能量是令人关注的。以更一般的方式,将CO 2巧妙地用作C 1原料并将其转化为有价值的碳基材料和能源可以成为建立封闭式CO 2循环的基础。这篇综述总结了最著名的TiO 2催化光催化利用CO 2的最新进展。基于系统。特别强调了不同结构(即晶相,形态,空位和缺陷),助催化剂和反应条件对催化剂性能的影响。此外,引起读者注意的是过去常常被忽略的氧化反反应。
