超小介孔纳米颗粒（<50 nm）作为一种独特的多孔纳米材料，以其介孔丰富、密度低、比表面积大、反应位点多、空腔空间大、本文首次综述了超小无机介孔纳米粒子的制备、功能化和应用的最新进展。与硬模板和无模板方法相比，软单胶束引导方法在介孔纳米粒子的合成中更加灵活。这是因为两亲性胶束具有可调节的功能块、受控的分子质量、构型和介观结构。以软胶束导向法为重点，单胶束可分为四种类型，即Pluronic型嵌段共聚物单胶束、实验室合成的两亲性嵌段共聚物单胶束、单分子星形嵌段共聚物单胶束和小分子嵌段共聚物单胶束。阴离子/阳离子表面活性剂单胶束。本文还回顾了内部介孔和外表面的功能化，包括构建蛋黄壳结构（封装的纳米颗粒）、锚定填充在壳上的活性成分以及构建不对称的 Janus 结构。然后，介绍了涉及催化、能量存储和生物医学的几个代表性应用。最后，展望了未来超小介孔纳米粒子的可控合成和大规模应用的前景和挑战。

Ultrasmall Inorganic Mesoporous Nanoparticles: Preparation, Functionalization, and Application

Ultrasmall mesoporous nanoparticles (<50 nm), a unique porous nanomaterial, have been widely studied in many fields in the last decade owing to the abundant advantages, involving rich mesopores, low density, high surface area, numerous reaction sites, large cavity space, ultrasmall size, etc. This paper presents a review of recent advances in the preparation, functionalization, and applications of ultrasmall inorganic mesoporous nanoparticles for the first time. The soft monomicelles-directed method, in contrast to the hard-template and template-free methods, is more flexible in the synthesis of mesoporous nanoparticles. This is because the amphiphilic micelle has tunable functional blocks, controlled molecule masses, configurations and mesostructures. Focus on the soft micelle directing method, monomicelles could be classified into four types, i.e., the Pluronic-type block copolymer monomicelles, laboratory-synthesized amphiphilic block copolymers monomicelles, the single-molecule star-shaped block copolymer monomicelles, and the small-molecule anionic/cationic surfactant monomicelles. This paper also reviews the functionalization of the inner mesopores and the outer surfaces, which includes constructing the yolkshell structures (encapsulated nanoparticles), anchoring the active components packed on the shell and building an asymmetric Janus architecture. Then, several representative applications, involving catalysis, energy storage, and biomedicines are presented. Finally, the prospects and challenges of controlled synthesis and large-scale applications of ultrasmall mesoporous nanoparticles in the future are foreseen.
