Biofouling is a common and expensive problem in medical, food, and maritime industries. Artificial nanozymes as functional mimics of haloperoxidases that boost the formation of cytotoxic hypohalous acids from halides and H2O2 are showing increasing potential as a novel class of ecofriendly antibiofouling materials to combat biofilm formation. A photothermal nanozyme (Mo SA‐N/C) with Mo single atoms as active sites that exhibits haloperoxidase‐mimicking capacity is herein developed. Density functional theory calculations indicate that hydroxyl radical from H2O2 dissociation is the key intermediate for hypobromous acid formation. Upon photoirradiation, Mo SA‐N/C generates heat and accelerates the reaction kinetics substantially. Finally, it is demonstrated that Mo SA‐N/C exerts superior broad‐spectrum antibacterial activity and can be applied as an effective coating additive for inhibiting biofouling in real marine conditions. Taken together, this study opens an avenue for developing biocompatible and photo‐response artificial enzymes for our fight against marine biofouling.

The photothermal process has attracted considerable attention in water treatment due to its advantages of low energy consumption and high efficiency. In this respect, photothermal materials play a crucial role in the photothermal process. Particularly, carbonaceous materials have emerged as promising candidates for this process because of exceptional photothermal performance. While previous research on carbonaceous materials has primarily focused on photothermal evaporation and sterilization, there is now a growing interest in exploring the potential of photothermal effect‐assisted advanced oxidation processes (AOPs). However, the underlying mechanism of the photothermal effect assisted by carbonaceous materials remains unclear. This review aims to provide a comprehensive review of the photothermal process of carbonaceous materials in water treatment. It begins by introducing the photothermal properties of carbonaceous materials, followed by a discussion on strategies for enhancing these properties. Then, the application of carbonaceous materials‐based photothermal process for water treatment is summarized. This includes both direct photothermal processes such as photothermal evaporation and sterilization, as well as indirect photothermal processes that assisted AOPs. Meanwhile, various mechanisms assisted by the photothermal effect are summarized. Finally, the challenges and opportunities of using carbonaceous materials‐based photothermal processes for water treatment are proposed.

“…[7][8][9] Currently, nanocarbon materials show wide application prospects in the field of environmental remediation, owing to their abundant reserves, metal-free characteristics, superior biocompatibility as well as great resistance to acids and alkalis. [10][11][12] Among the various allotropes of carbon, graphene with a unique two-dimensional monolayer structure has shown good potential for applications as adsorbents, catalysts, supercapacitors, and batteries due to its large surface area, high carrier mobility, and excellent conductance. [13][14][15] Generally, PMS activation from transition metals depends heavily on radical pathways.…”

“…53 The above inferences can be confirmed by EPR results. These active species obtained can degrade BPA efficiently, and eventually mineralize them into CO 2 and H 2 O (eqn (10)). According to the above analysis, the possible mechanisms of PMS activation for BPA degradation are more intuitively presented in Fig.…”
