Solar light is one of the most renewable energy resources. However, the limited light absorption range and low quantum efficiency of current semiconductors has immensely hindered the development of solar energy utilization technology and has been a matter of research priority. Opal/inverted opal photonic crystals (PCs) display a unique periodic structure, which can spontaneously enhance light–matter interactions and extend light propagation path, thus showing great potential in harvesting solar energy. The construction of opal/inverted opal photonic crystal photocatalyst (PCP) featured with attractive optical performance, which is originated from slow photons effect and multiple scatter effect, has been considered as an effective strategy to boost photocatalytic property. This review starts with the introduction of optical characteristics of PC, followed by discussion of fabrication strategies. Then, an overview of progress toward the application of PCP in photocatalytic hydrogen production, pollutant degradation, and CO2 reduction is provided as well. Finally, the challenging points and perspective are presented. It is expected that this review can provide valuable guidance for future design and synthesis of PCPs.

蛋白石/倒蛋白石光子晶体光催化剂的最新进展

太阳能是最可再生的能源之一。然而,目前半导体有限的光吸收范围和低量子效率极大地阻碍了太阳能利用技术的发展,一直是研究的重点。蛋白石/倒蛋白石光子晶体(PC)显示出独特的周期性结构,可以自发增强光与物质的相互作用并延长光的传播路径,因此在收集太阳能方面显示出巨大的潜力。蛋白石/倒蛋白石光子晶体光催化剂(PCP)的构建具有吸引人的光学性能,源于慢光子效应和多重散射效应,被认为是提高光催化性能的有效策略。本次回顾从介绍PC的光学特性开始,然后讨论制造策略。然后,概述了 PCP 在光催化制氢、污染物降解和 CO 中的应用进展还提供2减少。最后,提出了挑战点和观点。预计该综述可为未来五氯苯酚的设计和合成提供有价值的指导。
