Nanozymes in environmental remediation: A bibliometric and comprehensive review of their oxidoreductase-mimicking capabilities

Abstract

Nanozymes mimic enzyme-like properties and possess unique characteristics inherent to nanomaterials, combining catalytic functionality with distinct nanostructure features. This class of emerging materials has garnered significant attention for their potential applications in environmental remediation. A bibliometric analysis was conducted to map research trends and identify key areas of focus in this rapidly evolving field. This review comprehensively examines the types and catalytic mechanisms of oxidoreductase nanozymes, and their diverse environmental applications with specific attention to detection and degradation of various pollutants such as dyes, pesticides, antibiotics and toxic ions. The intricate mechanisms of oxidoreductases mimicked by nanozymes and their roles in catalysing reactions for environmental remediation are discussed. Furthermore, their versatility and efficacy in addressing environmental challenges are elaborated with recent literature. Through a thorough analysis of recent advancements and case studies, this review provides valuable insights into the potential of nanozymes as efficient tools for sustainable environmental management.
