Photocatalytic CO conversion to hydrocarbons (sometimes referred to as 'artificial photosynthesis'), which mimics natural photosynthesis with purely inorganic photocatalysts, has the potential to simultaneously combat the energy crisis and the greenhouse effect. In more than half of all reported studies to date, TiO -based materials are used as the photocatalyst. Yet, the reaction conditions and reactor designs employed in previous studies cover a vast range, hindering mutual comparisons of observed activities and selectivity. In this work, a systematic literature study is attempted, including a selection of only such research publications which report experimental conditions of high purity and a proof of the carbon source (blank experiments, CO isotope labelling or stoichiometric O identification) for CO photoreduction. General trends were then detected and discussed, aiming to guide future research to more efficient photocatalytic systems.
光催化 CO 转化为碳氢化合物（有时也称为“人工光合作用”），它使用纯无机光催化剂模拟自然光合作用，有可能同时解决能源危机和温室效应。在迄今为止报告的半数以上研究中，TiO2 基材料被用作光催化剂。然而，以前研究中使用的反应条件和反应器设计范围广泛，阻碍了对观察到的活性和选择性的相互比较。在这项工作中，尝试进行了系统的文献研究，仅选择那些报告高纯度实验条件的研究出版物，并证明 CO 光还原的碳源（空白实验、CO 同位素标记或化学计量 O 鉴定）。然后检测和讨论了一般趋势，旨在指导未来的研究向更高效的光催化系统发展。
