“…Through DSC analysis, the phase -transition properties of paraffin and the compositions made from TiO2 foam have been investigated. The peak to the left of the primary peak results from a change in the homogeneously nucleated crystal rotator, which shows that paraffin's solid-solid phase, has been adjusted (Chen et al, 2020;Zhu et al, 2022). Most likely, this peak is associated with the rebuilding of the orthorhombic to the hexagonal crystal structure, which often occurs in various paraffin waxes.…”

“…Chen et al (2020) prepared new three-dimensional interconnected hierarchically porous anatase TiO2 foam with the mesoporous wall structure, via a sol-gel templating method. Zhu et al (2022) reported the synthesis of TiO2 NPs by sol-gel method, and found that TiO2 NPs have excellent chemical and thermal stability, and the band gap and surface area were calculated to be 3.2 eV and 64.041 m 2 /g. Nomura et al (2015) successfully developed the sol-gel synthesis method for TiO2 nanoparticles.…”

Phase change materials (PCM) can absorb or release a huge amount of latent heat in accordance with the increase or decrease of the surrounding temperature. Among all the studied PCMs, organic PCM paraffin has been chosen due to the large energy storage capacity for thermal energy storage (TES). The present work introduces a thermally modified phase change material by TiO2 foam impregnation in paraffin. Three TiO2/paraffin PCM composites TPCM1, TPCM2, and TPCM3 containing 10 wt.%, 15 wt.%, and 20 wt.% of TiO2 foam with paraffin have been successfully synthesized for thermal energy storage. The porous TiO2 foam can provide a high paraffin loading capacity of up to 80 % (TPCM3) due to hollow cavities. TiO2 foam is uniformly distributed over the inner and outer surface of the paraffin as a nano additive to enhance the thermal conductivity (TC) of the composite PCM. The structural, morphological, and thermal study revealed that doping of the supporting material has potentially modified all the criteria of PCM composite for TES. The highest leakage-proof result was obtained for 20 wt.% of TiO2 foam impregnated composite (TPCM3) by analysing mass loss across 500 thermal cycles in an oven at 80°C. The thermal reliability of the TPCM3 composite has also been investigated after 500 thermal cycles. The TPCM3 composite maintains its crystalline nature with homogeneous dispersion and thermal stability without affecting the thermal and chemical properties of the PCM. The latent heat of the TPCM3 composite reached 182.87 J/g, and the thermal conductivity has been calculated at 0.71 W/m-K, which is 3.73 times higher than paraffin. The results concluded that synthesized TPCM3 composite could be a potential candidate for TES due to chemical and physical compatibility, easy synthesis process, good thermal and chemical reliability, and acceptable energy storage capacity with enhanced thermal conductivity.

The current study intends to create TiO2 foam, SiO2 nanoparticles (NPs), and SiO2@TiO2 core‐shell nanostructure (CSN) with improved photocatalytic durability for the quick degradation of the textile industrial water pollutant in the presence of sunlight. The sol‐gel, Stöber, and chemical co‐precipitation methods have been used to synthesize TiO2 foam, SiO2 NPs, and SiO2@TiO2 CSN. X‐ray diffraction results have revealed the anatase phase of TiO2 foam, the amorphous nature of SiO2 NPs, and the amorphous nature of SiO2@TiO2 CSN due to equal wt.% of SiO2 NPs and TiO2 foam at 300 K. Field emission scanning electron microscope images show that the TiO2 foam, SiO2 NPs, and SiO2@TiO2 CSN exhibit cluster sheets, spherical, and spherical raspberry‐like homogeneous morphology. The ultraviolet spectrum confirmed that the TiO2 foam and SiO2@TiO2 CSN have a band gap of 2.9 eV and 3.4 eV. SiO2@TiO2 CSN has been shown an excellent decomposition rate of water pollutants (gentian dye) in comparison to TiO2 foam due to their better‐absorbing nature. Both NPs and CSN employed in the breakdown of gentian dye have been recycled and their original characteristics are preserved. The proposed SiO2@TiO2 CSN has a higher potential for application in developing self‐cleaning, long‐lasting, and air‐purifying materials.
