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.

“…With the continuous development of society, the problem of environmental pollution has become increasingly serious . Because water is essential to human survival, the use and protection of water resources is particularly important. , Frequently, wastewater containing organic compounds is difficult to remove completely by conventional physical methods and therefore needs to be facilitated by chemical technologies. − In recent years, advanced oxidation technology has developed rapidly, and a variety of means have been developed such as sulfate oxidation, ozone oxidation, Fenton oxidation, ultrasonic treatment, γ radiation, electrochemical oxidation, and plasma-assisted processes . It is very noteworthy that the development of photocatalytic oxidative degradation technology, which uses clean solar energy as an energy source, has received a lot of attention from scientists. − This process converts light energy into chemical energy through catalytic materials and acts on organic pollutants without producing other waste products.…”

The graphitic carbon nitride (g-C3N4)/nitrogen-doped carbon dots (NCDs)/silver (Ag) ternary composite catalysts for organic pollution degradation in aqueous solution were constructed using an interfacial electronic control mechanism with double doping of NCDs and Ag nanoparticles (NPs). NCDs can act as a bridge for electrons to guide the flow of photogenerated charge carriers. The Ag NPs acts as photosensitizers and electron acceptors, enhancing electron transport in the material. With the synergistic effect of NCDs and Ag NPs, the absorption range of the visible spectrum of the g-C3N4/NCDs/Ag catalyst is broadened, the excitation of electrons is enhanced, and the photogenerated electron–hole binding rate is slowed down. The experimental results showed that the degradation of several contaminants [methyl orange (MO), rhodamine B (Rh B), tetracycline hydrochloride, and chrysin hydrochloride] could be achieved within 100 min using a 300 W xenon lamp as the light source (λ > 400 nm). It is very noteworthy that the reaction rates of g-C3N4/NCDs/Ag catalysts for the degradation of MO and Rh B were 13.5 and 12.9 times higher than those of conventional g-C3N4, respectively. NCDs and Ag NPs are uniformly distributed inside the material by inducing g-C3N4 to undergo self-assembly, and thus the g-C3N4/NCDs/Ag catalysts exhibit a stable recycling performance. In addition, •O2 – was confirmed as the main active substance in the photocatalytic process by radical capture experiments and EPR tests, and •OH was used as a secondary site to assist in the photocatalytic degradation process. This design idea of a double-doped modulated g-C3N4 material is expected to be applied in more fields.

Separating valuable materials such as dyes from wastewater using membranes and returning them to the production line is a desirable environmental and economical procedure. However, sometimes, besides filtration, adsorption, and separation processes, pollutant destruction also can be suitable using photocatalytic membranes. The art of producing nanohybrid materials in contrast with nanocomposites encompasses nanomaterial synthesis as a new product with different properties from raw materials for nanohybrids versus the composition of nanomaterials for nanocomposites. According to the findings of this research, confirming proper synthesis of nanohybrid is one challenge that can be overcome by different analyses, other researchers' reports, and the theoretical assessment of physical or chemical reactions. The application of organic‐inorganic nanomaterials and frameworks is another challenge that is discussed in the present work. According to the findings, Nanohybrid Membranes (NHMs) can achieve 100% decolorization, but cannot eliminate salts and dyes, although the removal efficiency is notable for some salts, especially divalent salts. Hydrophilicity, antifouling properties, flux, pressure, costs, usage frequency, and mechanical, chemical, and thermal stabilities of NHMs should be considered.
