“…Microbial pathogens, which include various bacteria and viruses, are major health concerns to humans worldwide. They occasionally cause serious infectious disease pandemics, such as those caused by the novel coronavirus (COVID-19), severe acute respiratory syndrome coronavirus (SARS), swine influenza virus (H1N1), and Middle-East respiratory syndrome coronavirus (MERS) [ 16 ]. For the sake of human health, society needs effective microbial disinfection systems with enough versatility to attack airborne, waterborne, and foodborne pathogenic species.…”

“…Besides, TiO 2 could be a good option for microorganism disinfection that is low cost, requires minimal energy consumption, and is harmless and eco-friendly [ 46 , 47 ]. In the TiO 2 photocatalysis microorganism disinfection process, the ROS generated from photocatalytic processes after light irradiation plays the major roles [ 16 ]. To further boost the microbial pathogens inactivation performance of TiO 2 , we need to strengthen the producing amount of ROS species.…”

“…TiO 2 is also used in other industries: energy (energy production and storage), environment (degrading pollution in the air, wastewater, and indoors), human health and food (antibacterial, antivirus sterilization), cosmetics (sunscreen against UVA and UVB), and self-cleaning and antifogging products [ 14 , 15 ]. The antivirus potential of TiO 2 will certainly draw attention during the struggle with the COVID-19 coronavirus pandemic [ 16 ].…”

Titanium dioxide (TiO2) has garnered attention for its promising photocatalytic activity, energy storage capability, low cost, high chemical stability, and nontoxicity. However, conventional TiO2 has low energy harvesting efficiency and charge separation ability, though the recently developed black TiO2 formed under high temperature or pressure has achieved elevated performance. The phase-selectively ordered/disordered blue TiO2 (BTO), which has visible-light absorption and efficient exciton disassociation, can be formed under normal pressure and temperature (NPT) conditions. This perspective article first discusses TiO2 materials development milestones and insights of the BTO structure and construction mechanism. Then, current applications of BTO and potential extensions are summarized and suggested, respectively, including hydrogen (H2) production, carbon dioxide (CO2) and nitrogen (N2) reduction, pollutant degradation, microbial disinfection, and energy storage. Last, future research prospects are proposed for BTO to advance energy and environmental sustainability by exploiting different strategies and aspects. The unique NPT-synthesized BTO can offer more societally beneficial applications if its potential is fully explored by the research community.

“…The cell infectivity assay demonstrated that the virus strains were disinfected within one minute of UV exposure [11] . Although TiO 2 holds several advantages such as non-toxic, highly economical, and chemical stability, utilization of more sustainable resources including visible/solar light for microbial disinfection is highly desirable in the future [97] . More selective viral inactivation techniques, especially towards the disinfection of SARS-CoV-2 should be further established.…”

“…Moreover, the inert, non-toxic, and economic nature makes TiO 2 more favorable in the development and industrial process without the introduction of environmental issues [ 9 ]. During the ongoing COVID-19 coronavirus pandemic, TiO 2 as a potential, environment-friendly antivirus agent will gain more concerning in the practical applications [ [10] , [11] , [12] ].…”

A binder-free attachment method for TiO 2 on a substrate has been sought to retain high active photocatalysis. Here, we report a binder-free covalent coating of phase-selectively disordered TiO 2 on a hydroxylated silicon oxide (SiO 2 ) substrate through rapid microwave treatment. We found that Ti–O–Si and Ti–O–Ti bonds were formed through a condensation reaction between the hydroxyl groups of the disordered TiO 2 and Si substrate, and the disordered TiO 2 nanoparticles themselves, respectively. This covalent coating approach can steadily hold the active photocatalytic materials on the substrates and provide long-term stability. The binder-free disordered TiO 2 coating film can have a thickness (above 38 μm) with high surface integrity with a strong adhesion force (15.2 N) against the SiO 2 substrate, which leads to the production of a rigid and stable TiO 2 film. This microwave treated TiO 2 coating film showed significant volatile organic compounds degradation abilities under visible light irradiation. The microwave coated selectively reduced TiO 2 realized around 75% acetaldehyde degradation within 12 h and almost 90% toluene degradation after 9 h, also retains stable photodegradation performance during the cycling test. Thus, the microwave coating approach allowed the preparation of the binder-free TiO 2 film as a scalable and cost-effective method to manufacture the TiO 2 film that shows an excellent coating quality and strengthens the application as a photocatalyst under severe conditions.
