Energy and environmental issues are increasingly crucial to all industry sectors across Europe and the rest of the world because the primary energy sources remain fossil fuels. Our continued dependence on these limited reserves has led to significant climate change. The need to move to a more sustainable energy economy was well perceived at the COP26 summit held in Glasgow. However, chemical production still lags in utilising renewable carbon as a feedstock. The European Commission (EU) has already recognised the urgent need for progress through the European Green Deal, aiming to make Europe carbon neutral by 2050. To achieve this ambitious goal which will contribute to the MSCA's Green Charter, improvement in a wide range of technologies is required, and this must be driven by materials innovation. The proposed project (GreenPerovs: Green, Efficient, and Stable Halide Perovskites for Heterogeneous Photocatalysis) will contribute to a green and sustainable chemicals and energy future by exploring low-cost, environmentally friendly, and stable semiconductor photocatalysts based on 3D (bulk) and 2D (two-dimensional) halide perovskites. GreenPerovs will use density functional theory (DFT) to study material stability as a function of composition and simulated photocatalysed reactions, including H2 production through water splitting, CO2 reduction to methanol and formic acid, and photochemical removal of organic pollutants. The research will focus on developing new formulations for lead-free halide perovskites produced from earth-abundant elements, which have the potential either to replace traditional photocatalysts or increase the efficiency of commonly used photocatalysts.

能源和环境问题对欧洲和世界其他地区的所有行业越来越重要，因为主要能源仍然是化石燃料。我们对这些有限的储量的持续依赖导致了气候变化的巨大变化。在格拉斯哥举行的COP26峰会上，人们对进入更可持续的能源经济的需求得到了很好的看法。但是，化学生产仍然落后于利用可再生碳作为原料。欧洲委员会（EU）已经认识到迫切需要通过欧洲绿色协议进行进步，旨在到2050年将欧洲碳中和。要实现这一雄心勃勃的目标，这将有助于MSCA的绿色宪章，需要改善各种技术，这必须由材料创新驱动。拟议的项目（Greenperovs：绿色，高效和稳定的卤化物钙钛矿用于异质光催化）将通过探索基于3D（Bulk）和2D（Bulk）和2D（二维）perovsk的低成本，环境友好和稳定的半导体光催化来促进绿色，可持续的化学物质和能量未来。 Greenperovs将使用密度功能理论（DFT）来研究材料稳定性，这是组成和模拟的光角质反应的函数，包括通过水分分裂的H2产生，二氧化碳减少到甲醇和甲醇和甲醇以及有机污染物的光化学去除。这项研究将着重于开发由地球丰富元素产生的无铅卤化物钙壶的新配方，这些元素有可能取代传统的光催化剂或提高常用光催化剂的效率。
