Transition Metal Engineering of Molybdenum Disulfide Nanozyme for Biomimicking Anti-Biofouling in Seawater

“…Nanozymes, known as nanomaterials possessing enzyme-like functionalities, have been widely applied in biological systems because of their benign biocompatibility, chemical stability, tunable activity, and scalable manufacture capability. − Recently, exciting paradigms can be found for haloperoxidase-mimicking nanozymes, such as CeO 2 , V 2 O 5 , and tungsten engineering of metal–organic frameworks. − However, even though some impressive preliminary results have been achieved, very few nanozymes with intrinsic haloperoxidase-like activity have been developed so far. Layered transition metal dichalcogenides have demonstrated superior performance in many fields, such as solid lubricants, energy devices, petrochemical catalysis, and so forth, due to their physicochemical diversity, low cost, and chemical stability. − In view of these advantages, MoS 2 has been explored as a valuable nanozyme that exhibits multiple enzyme-mimicking activities, such as superoxide dismutases, catalases, and peroxidases, in combating oxidative stress and disinfecting drug-resistant bacteria. , Unfortunately, MoS 2 exhibited very poor haloperoxidase-mimicking activity, as experimentally revealed in this work. In fact, for a variety of catalytic applications, experimental and computational results have confirmed that the activity origin of layered MoS 2 could be attributed to the highly exposed edge sites. − From this perspective, significant research efforts are being conducted to regulate the catalytic performance of MoS 2 , including dimensional control, metallic and non-metallic doping, and defect engineering. − Among them, heteroatom engineering is an appealing pathway to enhance the redox ability of MoS 2 . , We therefore anticipate that the metallic heteroatom-doped MoS 2 could enhance haloperoxidase-mimicking activity and enrich our understanding on the relationship between the foreign metallic doping and biological mimicking reaction kinetically.…”
