چکیده
Development of photoactive chemical heat storage (PCHS) materials that can be isomerized without ultraviolet light and have outstanding performance as well high rate output capability under low temperature conditions is a core issue for effective solar thermal conversion. In this study, we report novel PCHS material by attaching ortho-tetrafluorinated azobenzene (AzoTF) onto reduced graphene oxide (rGO) photothermal conversion storage. By applying the strategy separating n → π* transition two different configurations AzoTF to field materials, AzoTF-rGO composite not only realizes isomerization with visible long life cycle, but also exhibits excellent fatigue resistance capability, which greatly increases its exploitation value. Moreover, shows remarkable density (Max. 345.8 kJ kg−1), power 2401.4 W kg−1) attribute intermolecular hydrogen bond strong interactions arise from attachment density. This new may paves way more efficient energy

High Temperature Phase Change Materials for Thermal Energy Storage Applications: Preprint
To store thermal energy, sensible and latent heat storage materials are widely used. Latent heat thermal energy storage (TES) systems using phase change materials (PCM) are useful because of their ability to charge and discharge a large amount of heat from a small mass at constant temperature during a phase transformation. Because high-melting-point PCMs have large energy densities, their use c...

متن کاملOne-pot, low-temperature synthesis of self-doped NaTaO3 nanoclusters for visible-light-driven photocatalysis.
Herein we first report the synthesis of self-doped NaTaO3 nanoclusters using a facile and one-pot low-temperature solvothermal method. Ta(4+) in bulk NaTaO3 greatly narrows its band gap from 3.94 to 1.70 eV and thus extends its photoresponse from the UV to the visible light region, which leads to enhanced visible-light photocatalytic activity for water splitting and dye degradation without load...
