“…α-Ti 2 O 3 with the ultra-narrow bandgap (≈0.1 eV) is a promising candidate for photothermal conversion. [43,96] Li et al [33,44,46,47] demonstrated that α-Ti 2 O 3 has strong broad absorption spanning the UV, visible, near-infrared (NIR) and MIR ranges with high absorption coefficients. High-performance photothermal conversion was achieved by Wang et al [43] in the α-Ti 2 O 3 nanoparticles with an average size of ≈400 nm (Figure 4a).…”

Titanium sesquioxide (Ti2O3) is drawing broad attention due to its fascinating physical properties and promising applications in the fields of energy, biomedicine, and electronics, among others. Its richness is due mainly to the strongly correlated 3d1 electrons on the Ti3+ sites. In stark contrast to titanium dioxide (TiO2), Ti2O3 has an ultra‐narrow bandgap (≈0.1 eV) at room temperature, resulting from strong correlation among the 3d1 electrons. Distinct electrical and optical properties are introduced in Ti2O3, accompanied with varied intriguing applications. Remarkable photothermal conversion, infrared photodetection, and electrocatalytic properties have been reported and explored in the past few years. Based on its unique and excellent properties, Ti2O3 has been utilized in seawater desalination, electrocatalytic water splitting, cancer therapy, hydrogen production, mid‐infrared photodetection, nitrogen fixation, Li‐ion batteries, etc. Herein, the fabrication, structural and electronic properties of Ti2O3 are comprehensively introduced, with a focused summary of recent research progress on its applications. Finally, current challenges, opportunities, and future perspectives of Ti2O3 are discussed.

“…The Ti 2 O 3 film was irradiated with NIR laser for 10 min, followed by turning off the laser for cooling the film to room temperature naturally. In this case, the increased temperature (DT) of Ti 2 O 3 film is about 121.4 C. The photothermal conversion efficiency h of Ti 2 O 3 film was calculated from the thermal profile of Figure 2C via the energy balance function (Bi et al, 2020;Ren et al, 2015Ren et al, , 2017Wang et al, 2017): 1)…”

“…Currently, various photothermal materials have been applied to SSG systems, such as carbon-based materials, − polymers, − semiconductor materials, − porous aerogels, − biomass-based materials, and so forth. − From a sustainable and practical development perspective, biomass and biomass waste-based materials have a particularly potential application value, owing to their eco-friendly nature, abundance, low cost, and high efficiency. − For example, Liu et al fabricated a sustainable biomass-based evaporator by using cuttlefish ink absorbent materials and chitosan hydrogels as skeletons. Also, the SSG evaporator can achieve an evaporation efficiency of 72.94% under 1 sun irradiation.…”

Solar steam generation (SSG) is an effective way to mitigate the freshwater crisis. However, challenges still remain in scalable preparation, cost-effectiveness, and expanding the scope of practical applications for photothermal materials. Herein, a biomass-based solar steam generator (named OR-INP) with salt-resistant, oil-repellent, and anti-fouling performances is fabricated by grafting poly(ionic liquid)s onto celluloses from waste newspapers and then conducting oil-repellent modification. Benefiting from the broad solar absorption in the wet state (ca. 92%), low thermal conductivity (0.1108 W m–1 K–1), and strong hydrophilic and oleophobic properties, the solar evaporation efficiency is as high as 93.25% for pure water, 84.96% for 20 wt % NaCl, and 78.46% for 5 wt % oily wastewater, under 1 sun irradiation. Moreover, the aerogel still has excellent purification effects on solutions which contain organic dyes, heavy metal ions, or bacteria. Therefore, combining the merits of salt resistance, oil repellency, and wastewater treatment, this work develops the prospect of employing waste biomass resource-based photothermal materials and expands the practical application range of biomass-based evaporators.
