Abstract Mesocrystal—a new class of crystals compared with conventional single crystals and randomly distributed nanocrystal systems—has captured significant attention in recent decades. Current studies have been focused on the advanced synthesis as well as the intriguing properties of mesocrystal. In order to create new opportunities upon functional mesocrystals, they can be regarded as a new functional entirety when integrated with unique matrix environments. The elegant combination of mesocrystals and matrices has enabled researchers to realize enthralling tunabilities and to derive new functionalities that cannot be found in individual components. Therefore, mesocrystal-embedded system forms a new playground towards multifunctionalities. This review article delivers a general roadmap that portrays the enhancement of intrinsic properties and new functionalities driven by novel mesocrystal-embedded oxide systems. An in-depth understanding and breakthroughs achieved in mesocrystal-embedded oxide systems are highlighted. This article concludes with a brief discussion on potential directions and perspectives along this research field.
Introduction Mesocrystals, the ordered nanocrystal superstructures, with intriguing properties and versatile functionalities, have been the focus in the fields of solid-state chemistry and condensed matter physics over the past decades due to their exciting potential for cutting-edge researches and innovative applications.[1,2] In contrast to randomly distributed nanocrystal and single-crystal systems, mesocrystal is a collective system composed of individual functional nanocrystals showing the same crystallographic connectivity, as illustrated in Fig. 1. The mesocrystal itself with interspersed environment forms a functional system, mesocrystal-embedded system, offering fruitful properties and possibilities to impact the modern technology for catalytic, electronic, optical, magnetic, drug delivery, and reaction precursor applications.[3,4] Due to their structural nature, the mesoscopically well-ordered crystals can exhibit unique properties and functionalities that cannot be seen in the parent bulk materials. Typical examples of mesocrystals can be found in various materials as diverse as metal oxides,[5–9] II/IV semiconductors,[10,11] complex oxides,[12,13] fluorides,[14] phosphates,[15] organic molecular systems,[16,17] etc. To date, considerable effor
