It is well known that two-dimensional(2D)MXene-derived quan-tum dots(MQDs)inherit the excellent physicochemical properties of the parental MXenes,as a Chinese proverb says,"Indigo blue is extracted from the indigo plant,but is bluer than the plant it comes from."Therefore,0D QDs harvest larger surface-to-volume ratio,outstanding optical properties,and vigorous quantum confinement effect.Currently,MQDs trigger enormous research enthusiasm as an emerging star of functional materials applied to physics,chemistry,biology,energy conversion,and storage.Since the surface properties of small-sized MQDs include the type of surface functional groups,the functionalized surface directly determines their performance.As the Nobel Laureate Wolfgang Pauli says,"God made the bulk,but the surface was invented by the devil,"and it is just on the basis of the abundant surface functional groups,there is lots of space to be thereof excavated from MQDs.We are witnessing such excellence and even more promising to be expected.Nowadays,MQDs have been widely applied to catalysis,whereas the related reviews are rarely reported.Herein,we provide a state-of-the-art overview of MQDs in catalysis over the past five years,ranging from the origin and development of MQDs,synthetic routes of MQDs,and functionalized MQDs to advanced characterization techniques.To explore the diversity of catalytic application and perspectives of MQDs,our review will stimulate more efforts toward the synthesis of optimal MQDs and thereof designing high-performance MQDs-based catalysts.
