“…Obvious folds and depressions were observed at 20 min, which was consistent with the above bactericidal performance. The coagulation test can be used to detect the residue of live bacteria because live bacteria can produce coagulase to coagulate rabbit plasma [25] . The corresponding angle decreased from 33.3° (0 min) to 22.6° (20 min), indicating that there were no residual live bacteria after 20 min of visible-light irradiation ( Figure 2 j).…”

“…Generally speaking, single-component photocatalysts often have a narrow range of photoabsorption, slow e – /h + pairs separation, and weak redox performance . In recent years, the design strategy of heterojunction construction has become a useful method to prepare efficient photocatalysts, that is, the combination of semiconductors with a narrow band gap and semiconductors with a wide band gap to form heterojunction structures. − Heterogeneous structures can inhibit the recombination of e – and h + pairs, prolong the of photoresponse range, and thus improve the efficiency of photocatalysis. , Up to now, according to the band gap as well as the VB and the CB potential of photocatalysts, the typical heterojunctions involve Type I, Type II, and Type III heterojunctions (Figure A–C).…”

Nowadays, the increasing emergence of antibiotic-resistant pathogenic microorganisms requires the search for alternative methods that do not cause drug resistance. Phototherapy strategies (PTs) based on the photoresponsive materials have become a new trend in the inactivation of pathogenic microorganisms due to their spatiotemporal controllability and negligible side effects. Among those phototherapy strategies, photocatalytic antimicrobial therapy (PCAT) has emerged as an effective and promising antimicrobial strategy in recent years. In the process of photocatalytic treatment, photocatalytic materials are excited by different wavelengths of lights to produce reactive oxygen species (ROS) or other toxic species for the killing of various pathogenic microbes, such as bacteria, viruses, fungi, parasites, and algae. Therefore, this review timely summarizes the latest progress in the PCAT field, with emphasis on the development of various photocatalytic antimicrobials (PCAMs), the underlying antimicrobial mechanisms, the design strategies, and the multiple practical antimicrobial applications in local infections therapy, personal protective equipment, water purification, antimicrobial coatings, wound dressings, food safety, antibacterial textiles, and air purification. Meanwhile, we also present the challenges and perspectives of widespread practical implementation of PCAT as antimicrobial therapeutics. We hope that as a result of this review, PCAT will flourish and become an effective weapon against pathogenic microorganisms and antibiotic resistance.

“…Current technologies mostly rely on the doping of narrow-bandgap semiconductors as well as composite photocatalytic systems. [12,40,41] Modulation of the bandgap structure of photocatalysts can benefit for using NIR or the full region of the solar spectrum. Furthermore, combining at least two strategies, such as bandgap engineering, up-conversion, and surface plasmon resonance (SPR), can indirectly realize full-solar-spectrum photocatalysis.…”

The ability to use the full solar spectrum energy in photocatalytic processes for environmental remediation and energy production has attracted worldwide attention. Efficient harvesting of near‐infrared (NIR) photons, especially in the wavelength range beyond 800 nm, is one of the main driving forces in photocatalytic research. The design of appropriate photocatalytic systems for wide‐range light‐harvesting from the UV to NIR regions is a promising method of maximizing the efficiency of solar energy utilization. This review comprehensively summarizes the recent progress in full‐solar‐light‐driven photocatalytic systems, including several strategies to harness NIR light and thermal energy. The corresponding photocatalytic mechanisms and design of binary or ternary heterogeneous systems are discussed in detail. Moreover, future perspectives and challenges are presented to inspire the development of further innovations in full‐solar‐light‐driven photocatalysis.
