Carbon dioxide release by human activity is the major cause of global warming. Decreasing the concentration of CO2 in the atmosphere is a challenge that needs to be addressed. In addition to their negative impact on the environment, the availability of petroleum-based fuel is decreasing. The photoconversion of CO2 into so-called green solar fuel is a possible alternative to reduce the quantity of carbon dioxide in the atmosphere aiming the limitation of greenhouse effect. Among the photocatalyst studied for these reactions, the perovskite-based appeared as one of the most promising class of materials. These materials possess unique optoelectronic properties and exhibit significant variability in terms of their dimensionality, structure, morphology, grain size, and tunable band gap, as well as the position of their valence band and conduction band. This review discusses both the classics and innovative perovskite synthesis methods such as solid-state reaction, hydrothermal and solvothermal synthesis, hot injection or chemical precipitation. Then, the use of these materials for the photoreduction of CO2 into fuel such as formic acid, methanol and methane is detailed.

二氧化碳转化为太阳能燃料：无机钙钛矿的设计和反应性

人类活动释放的二氧化碳是全球变暖的主要原因。降低大气中二氧化碳的浓度是一个需要解决的挑战。除了对环境产生负面影响外，石油燃料的可用性也在下降。将二氧化碳光转化为所谓的绿色太阳能燃料是减少大气中二氧化碳含量的一种可能的替代方案，旨在限制温室效应。在针对这些反应研究的光催化剂中，钙钛矿基材料似乎是最有前途的材料之一。这些材料具有独特的光电特性，并在尺寸、结构、形态、晶粒尺寸、可调带隙以及价带和导带位置方面表现出显着的变化。本综述讨论了经典和创新的钙钛矿合成方法，如固态反应、水热和溶剂热合成、热注射或化学沉淀。然后，详细介绍了这些材料用于将二氧化碳光还原成甲酸、甲醇和甲烷等燃料的用途。
