Researchers from Zhengzhou University and the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences have developed a smart material that combines hollow multishelled structure (HoMS) TiO2 and a heat-sensitive polymer in order to automatically control heat transmission.

This study was published in Green Energy & Environment on Jan. 20.

Heat is the most widely used driving force for chemical reactions, but the combustion of fossil fuels leads to huge CO2 emissions. Effective thermal energy management is a key imperative for green production.

Developing an intelligent material that can automatically control heat transfer is a way to limit such emissions. The goal of this intelligent material is to perform thermal insulation at relatively low temperatures while dissipating heat when the reaction system overheats.

"HoMS is assembled from multiple shells and independent closed cavities between shells. It has unique properties of energy transfer and is quite a special structure among all hollow materials," said Prof. WANG Dan from IPE.

The rapid development of HoMS started with the development of sequential templating approach in 2009, and years of study has found it possesses the advantage in effective surface exposure and optimized mass transport.

A hollow structure with multishells can provide more interfaces and thus further inhibit heat convection and transmission, thus making it more favorable for heat isolation.

The HoMS–polymer composites possess an intelligent thermal insulation behavior and exhibit excellent thermal insulation properties below the given temperature. If the system overheats, the thermal conductivity automatically increases to release the stored energy.

The study shows that the thermally responsive polymer is a promising model for building thermal fields and reveals for the first time the mode of heat transfer through HoMS. This composite exhibits an unusual two-stage endothermic behavior whereby the direction of heat flow in the material matrix changes. The energy is accumulated in HoMS, which operates as a heat reservoir to regulate the thermal flow.

This work provides a new avenue for designing smart reactors for the green chemical industry, thus creating more opportunities for heat-related applications and increasing the potential for efficient energy use.

Solar-thermal interfacial evaporation has been considered the most promising strategy for addressing this problem. However, developing an optimized material featuring both efficient solar-vapor conversion and good environmental tolerance still remains challenging.

Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences have developed an ultra-stable amorphous Ta2O5/C nanocomposite with a hollow multishelled structure (HoMS) for solar evaporation, which can improve the efficiency of water purification.

The study was published in Advanced Materials on Oct. 29.

"The precise atomic and composition control in the building block of HoMS realizes an indirect bandgap structure with abundant energy states around the Fermi level, which enhances nonradiative relaxation to facilitate photothermal conversion," said Prof. Wang Dan, the corresponding author of the study, "The unique hollow multishelled structure can efficiently enhance light absorption like a blackbody."

HoMS decreases the energy required for water evaporation. Simulation results show that HoMS establishes a thermal field gradient, thus providing the driving force for vapor evaporation.

"HoMS also benefits water transport," said Wang, "The confined cavities in HoMS promote liquid water diffusion owing to the capillary pumping effect, and the nanopores in HoMS induce water molecules to evaporate in the form of clusters, thus enabling evaporation with less enthalpy."

With highly efficient photoabsorption and photothermal conversion, a super-fast evaporation speed of 4.02 kg m-2h-1 has been achieved. The evaporation speed barely changed after 30 days, and with no salt accumulation, indicating a long-term stability.

Notably, the concentration of pseudovirus SC2-P could be decreased by six orders of magnitude after evaporation.

This amorphous Ta2O5/C composite is readily fabricated, carried, stored, and recycled. It can be applied to the purification of seawater, or to heavy metal- or bacteria-containing water, obtaining drinkable water that meets the standard of the World Health Organization.

The scientists from IPE are preparing a prototype of seawater desalination for the residents on isolated islands.
