Abstract

Hybrid halide perovskites (HaPs) represent a class of material with excellent optoelectronic properties providing distinct avenues for disruptive photo(-electro) catalytic technologies. However, their photocatalytic activity, selectivity and stability remains a scientific and technological hurdle. In this perspective, we discuss fundamental aspects of perovskite based photocatalytic systems, specifically for CO2 conversion and high value oxidation reactions, and highlight critical limiting factors and on-going challenges in the field. We critically assess the recent advances in designing halide perovskite hetero-interfaces and characterization methodologies which are often used to define the performance metrics. Furthermore, we outline important questions and identify emerging trends in relation to the remediation strategy towards improved photocatalytic performance and stability from halide perovskite semiconductors.

光电化学太阳能到燃料转换中的混合包覆晶石闪耀光芒
混合卤化物过氧化物(HaPs)是一类具有优异光电特性的材料,为颠覆性光(电)催化技术提供了独特的途径。然而,它们的光催化活性、选择性和稳定性仍然是一个科学和技术障碍。在这一视角中,我们讨论了基于包晶石的光催化系统的基本方面,特别是二氧化碳转化和高价值氧化反应,并强调了该领域的关键限制因素和持续挑战。我们认真评估了在设计卤化物包晶异质界面和表征方法方面的最新进展,这些方法通常用于确定性能指标。此外,我们还概述了与改善卤化物包晶半导体光催化性能和稳定性的补救战略有关的重要问题,并确定了新出现的趋势。
