摘要
In Earth systems,thousands of terragrams(Tg)(1 Tg=10^(12) g)of mineral nanoparticles move around annually.Some mineral nanoparticles have exhibited unexpected intrinsic enzyme-like characteristics(so called“mineral nanozymes”),and are ubiquitously distributed in natural ecosystems such as the atmosphere,oceans,waters,and soils.Compared with natural enzymes,these mineral nanozymes have several advantages such as tunable catalytic efficiency and robustness to harsh conditions,e.g.,heat,acid,and alkaline conditions.As mineral nanozymes are new products of multidisciplinary cross-cutting,they have been widely applied in various fields.This review,for the first time,systematically introduces the species and properties of mineral nanozymes in Earth systems,discusses the critical roles played by nanozymes in environmental biogeochemical cycles,compiles the interfacial processes and mechanisms of mineral nanozymes,and provides an overview of the future prospects of mineral nanozymes.
