Steady-state and time-resolved photoluminescence for innovative development of solar-to-fuel photocatalysts

减少排放到大气中的污染物数量，并将现有污染物转化为有价值的物质，是与全球变暖和温室效应作斗争的关键。特别是，将二氧化碳分子转化为燃料是最有前途的解决方案之一，在全球公共和科学部门都引起了极大的关注。为此，人们已经成功地设计和研究了不同的催化和光催化替代品。后一种方法更具吸引力，因为可以通过收集阳光将二氧化碳分子转化为CO、CH4、甲醇、C2+碳氢化合物。这些产品不仅对大气的危害较小，而且是化学工业的基本原料。然而，获得高选择性和高活性的光催化体系仍然是一个必须克服的挑战，需要进一步的研究来做到这一点。目前的研究方案需要一台用于寿命分辨和稳态光致发光的荧光光谱仪，这将允许对我们研究组获得的光催化系统进行强有力的表征。这一仪器对于得出新的结论，为我们的研究提供新的方向，并探索对所开发的催化系统进行不同的修改是至关重要的。

Reducing the number of pollutants emitted into the atmosphere and transforming the existing ones into valuable substances are critical points in the struggle against global warming and the greenhouse effect. Especially, the transformation of CO2 molecules into fuels is one of the promising solutions that has attracted significant attention in both public and scientific sectors around the globe. For this purpose, different catalytic and photocatalytic alternatives have been successfully designed and studied. The latter approach is much more attractive due to the possibility of harvesting sunlight to convert CO2 molecules into CO, CH4, methanol, C2+ hydrocarbons. These products are not only less harmful to the atmosphere but are also essential feedstocks for the chemical industry. However, the obtention of highly selective and active photocatalytic systems is still a challenge that has to be overcome, and further research needs to be developed to do so. The current research proposal requests a spectrofluorometer for lifetime-resolved and steady-state photoluminescence, which will allow strong characterization of the photocatalytic systems obtained in our research group. This instrument is crucial to derive new conclusions, take new directions on our research, and explore different modifications to the catalytic systems developed.
