Hydrophobic LDH-Tailored Exfoliated Graphene Sheet Energy Harvester: Harnessing Pressure-Driven Heating and Electrolysis for Advanced Real Applications.

ABSTRACT: Hydrovoltaic harvesting converts water-solid interactions into electricity, offering a sustainable power route across diverse settings. Yet most systems are hard to scale, suffer evaporation-limited lifetimes, and lack multifunctionality, limiting real-world application. To overcome these limitations, a highly optimized multifunctional hydrovoltaic harvester is developed by integrating exfoliated graphene oxide sheet (EGs) and hydrophobic layered double hydroxide (LDH) coatings onto a porous melamine foam scaffold. The porous foam ensures rapid, capillary-driven water transport, the EGs coating forms continuous conductive pathways, lowering device resistance to 600 Ω and enabling efficient electron transfer, and the hydrophobic LDH layer suppresses evaporation, sustaining stable energy gen
