Photocatalysts provide a sustainable way to remove pollutants or store energy in the form of solar fuels by processes such as water splitting and CO₂ photoreduction (artificial photosynthesis). Research in this topic is an expansive field evidenced by the large number of contributions published in the past few years. Hybrid photocatalysts based on inorganic semiconductors (ISs) and conjugated polymers (CPs) have emerged as novel promising photoactive materials. In addition to the well-known behaviour of ISs in photocatalytic processes, CPs have emerged as an interesting alternative to improve the photocatalytic efficiency due to the possibility of controlling their optoelectronic, textural and morphological properties at the molecular level. Thus, the synergy between ISs and CPs leads to more efficient photocatalysts with enhanced light absorption in the overall solar spectrum, improved photocharge generation and transport, higher stability to photo-corrosion and higher surface areas. Here, we present an overview of the advances in the development of hybrid IS–CP photocatalysts for pollutant degradation and energy conversion through water splitting, CO₂ reduction and/or N₂ fixation using photo- and photo(electro)catalytic processes.

基于共轭聚合物和无机半导体作为光催化剂的杂化材料：从环境到能源应用

光催化剂提供了一种可持续的方式，可以通过水分解和CO ₂等过程以太阳能的形式去除污染物或以太阳能的形式存储能量光还原（人工光合作用）。过去几年中发表的大量论文证明了对该主题的研究是一个广阔的领域。基于无机半导体（ISs）和共轭聚合物（CPs）的杂化光催化剂已经成为新型的有前途的光敏材料。除了IS在光催化过程中的众所周知的行为外，由于可以在分子水平上控制其光电，质构和形态学性质，CP成为提高光催化效率的有趣替代方法。因此，IS与CP之间的协同作用导致更有效的光催化剂，在整个太阳光谱中具有增强的光吸收，改善的光电荷产生和传输，对光腐蚀的更高稳定性和更大的表面积。这里，使用光催化和光（电）催化过程进行₂还原和/或N₂固定。
