论文摘要
最近，铁电体与电化学反应的偶联引起了人们对收集废热的兴趣。用温度的铁电的极化的变化可用于影响化学反应，尤其是当材料在其库里温度附近循环时。从这个角度来看，我们通过收集废热能量并探索其潜在的电化学应用，例如水处理，空气净化和产生氢，从而介绍了pyroelectric控制电化学过程的原理。作为推动电化学反应的新兴方法，在环境中存在热波动和/或瞬态废热的存在可能是推动pyroelectric极化变化以释放此类反应的电荷的主要热输入。有许多途径需要探索，我们总结了形成多功能或混合材料的策略以及未来的方向，例如选择低居里温度（<100°C）的pyroelectrics（<100°C），提高的热导率，增强的表面积或孔隙率，表面积或孔隙率，定制的微观结构和能够在较大温度范围内运行的系统。
Recently, the coupling of ferroelectrics with electrochemical reactions has attracted increasing interest for harvesting waste heat. The change of polarisation of a ferroelectric with temperature can be used to influence chemical reactions, especially when the material is cycled near its Curie temperature. In this perspective, we introduce the principle of pyroelectric controlled electrochemical processes by harvesting waste heat energy and explore their potential electrochemical applications, such as water treatment, air purificiation and hydrogen generation. As an emerging approach for driving electrochemical reactions, the presence of thermal fluctuations and/or transient waste heat in the environment has the potential to be the primary thermal input for driving the change in polarisation of a pyroelectric to release charge for such reactions. There are a number of avenues to explore and we summarize strategies for forming multi-functional or hybrid materials and future directions such as selecting pyroelectrics with low Curie temperature (< 100 °C), improved heat conductivity, enhanced surface area or porosity, tailored microstructures and systems capable of operating over a broader temperature range.
