Tightened 1D/3D carbon heterostructure infiltrating phase change materials for solar–thermoelectric energy harvesting: Faster and better

Extensive use of thermal energy in daily life is ideal for reducing carbon emissions to achieve neutrality; however, the effective collection a major hurdle. Thermoelectric (TE) conversion technology based on Seebeck effect and storage phase change materials (PCMs) represent smart, feasible, research-worthy approaches overcome this However, integration multiple sources freely existing environment output electrical simultaneously still remains huge challenge. Herein, three-dimensional (3D) nanostructured metal–organic frameworks (MOFs) are situ nucleated grown onto nanotubes (CNTs) via coordination bonding. After calcination, prepared core–shell structural [email protected] transformed into tightened 1D/3D heterostructure loading Co nanoparticles efficient solar–thermoelectric harvesting. Surprisingly, corresponding composite PCMs show record-breaking solar–thermal efficiency 98.1% due local surface plasmon resonance nanoparticles. Moreover, our designed all-in-one also capable creating an potential 0.5 mV without TE generator. This promising approach can store simultaneously, providing new direction design advanced multifunctional utilization.
