“…Since then, photocatalysis has attracted broad attention and made numerous achievements in different application fields, such as organic synthesis, environmental purification, solar energy conversion, and so on . In recent years, as one of the phototherapy strategies, photocatalysis technology-based photocatalytic antimicrobial therapy (PCAT) has been widely studied, becoming a green and promising alternative strategy for the treatment of antibiotic-resistant pathogens . Compared with antibiotics, the PCAT strategy holds the following advantages: (i) it has effective antimicrobial action against various kinds of microbial species, such as bacteria, fungi, viruses, and parasites; (ii) it is a low-cost and green inactivation method since solar energy is an abundant renewable resource; (iii) most importantly, the produced reactive oxygen species (ROS) can effectively and persistently inactivate microorganisms, which does not easily lead to the occurrence of resistance in pathogens …”

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.

“…Future research in this area of selective reactivity will require investigations not only of the processes themselves but also of their technological feasibility, which may also involve novel reactor concepts. So far, most reactors are either designed for reactants in the liquid phase, as for water-splitting and wastewater treatment, or are constructed for the purification of air for environmental remediation. , The latter topic has attracted increased attention due to the SARS-COV-2 pandemic, but hitherto it considers neither a controlled chemical environment nor the possibility to yield certain products. However, when speculating about photocatalytic reactions with gaseous reactants, such processes may feature different advantages over liquid systems, such as the temperature range of operation or the mass transport (e.g., areas of oversaturation at the photocatalyst of gaseous products in the liquid environment).…”

Heterogeneous photocatalytic systems are usually described based on electrochemistry, which the vast majority of interpretations and strategies for optimizing photocatalysts rely on. Charge carrier dynamics are usually in the spotlight, whereas the surface chemistry of the photocatalyst is neglected. This is unjustified, because studies on alcohol photoreforming on metal-decorated rutile single crystals revealed that the electrochemical reaction model is not generally applicable. Hence, many photocatalytic reactions may proceed in a different manner and the thermal chemistry needs to be accounted for. The new mechanism is particularly relevant for reactions in gaseous environments in the absence of solvated ionic species. Here, we compare both mechanisms and highlight their differences and consequences for photocatalysis. Based on alcohol photochemistry, we demonstrate the importance of thermal reactions in photocatalytic mechanisms and the relevance of systematic studies in different environments for a holistic understanding of photocatalysis.
