摘要

水蒸发是一个重要的自然过程,通过水力发电技术为可持续能源生产提供了重要机会。然而,实际实施受到能量输出不足、制造工艺复杂、可靠性有限和成本高的阻碍。本研究提出了一种循环输运驱动的水力发电机(CTHG),模拟树木蒸腾作用,利用循环水流来增加电荷分离,稳定电压输出,提高功率密度。该系统减少了对外部供水的依赖,同时保证了持续的运行稳定性,为可再生能源发电提供了可扩展和有效的选择。这种CTHG利用分层多孔去木质素木材与普鲁士蓝(PB)纳米颗粒和导电聚苯胺(PANI)功能化作为能量产生的介质,增强水的运动,电导率和离子扩散。在理想条件下,该器件的连续电压为0.76 V,约为已发表平均电压的两倍,在去离子水中的功率密度为6.75 μW cm⁻²。在高温碱性溶液中,电压增加到0.92 V,并在多天内观察到一致的性能。此外,串联连接的cthg有效地为商业设备供电,例如,照亮由五个单元串联连接的LED灯。这种可扩展的、环境可持续的技术突出了生物基材料在可再生能源生产和废水回收方面的前景,解决了重大的全球能源问题。

Spontaneous Cyclic Transport Mediated Hydrovoltaic Energy Harvesting Utilizing PB-PANI infused Hierarchical Porous Wood Structures
Water evaporation, a crucial natural process, presents significant opportunities for sustainable energy production via hydrovoltaic technology. Nevertheless, actual implementations are hindered by insufficient energy output, complex fabrication processes, limited reliability, and high costs. This research presents a Cyclic Transport-Driven Hydrovoltaic Generator (CTHG), modeled after tree transpiration, which utilizes cyclic water flow to augment charge separation, stabilize voltage output, and enhance power density. The system reduces dependence on external water supplies while guaranteeing sustained operational stability, providing a scalable and effective option for renewable energy generation. This CTHG utilizes hierarchically porous delignified wood functionalized with Prussian blue (PB) nanoparticles and conductive polyaniline (PANI) as the medium for energy generation, enhancing water movement, electrical conductivity, and ion diffusion. Under ideal conditions, the device achieves a continuous voltage of 0.76 V, approximately twice the published average, and a power density of 6.75 μW cm⁻² in deionized water. The voltage increases to 0.92 V in alkaline solutions at elevated temperatures with consistent performance observed over multiple days. Furthermore, series-connected CTHGs efficiently energize commercial devices, exemplified by illuminating an LED light with five units connected in series. This scalable, environmentally sustainable technique highlights the promise of bio-based materials for renewable energy production and wastewater reclamation, tackling significant worldwide energy issues.
