Development of bifunctional microencapsulated phase change materials with crystalline titanium dioxide shell for latent-heat storage and photocatalytic effectiveness

Design and synthesis of multifunctional microencapsulated phase change materials with silver/silica double-layered shell for thermal energy storage, electrical conduction and antimicrobial effectiveness

“…There have been some successful cases in our study. For example, the microencapsulated PCMs with a crystalline TiO 2 shell revealed the antibacterial and photocatalytic effectiveness other than the latent heat-storage capability [37]. The microencapsulated PCMs presented the fluorescent and magnetic characteristics when fabricated with the zirconium oxide and ferriferous oxide shells, respectively [38e41].…”

A novel photo-thermochemical cycle for the dissociation of CO 2 using solar energy

“…9; the peaks centred at 463.2 eV and 457.5 eV can be assigned to Ti 3+ 2p 1/2 and Ti 3+ 2p 3/2 , respectively. The peaks located at 464.3 eV and 458.6 eV are assigned to Ti 4+ 2p 1/2 and Ti 4+ 2p 3/2 , respectively [36,37]. It is obvious that Ti 4+ was presence before and after UV irradiation, but there was hardly any Ti 3+ before UV irradiation.…”

Microencapsulation of phase change materials with binary cores and calcium carbonate shell for thermal energy storage

“…Latibar et al [27] synthesized microcapsules with palmitic acid as core and silicon dioxide (SiO 2 ) as shell materials that observed a significant improvement in thermal conductivity. Chai et al [28] fabricated the microencapsulated n-eicosane with titanium dioxide (TiO 2 ) shell through sol-gel process and indicated that the heat transfer capability of n-eicosane has been greatly enhanced. Zhang et al [29] packaging n-eicosane into germanium dioxide (ZrO 2 ) shells which achieved high thermal storage capability and good thermal stability.…”
