“…32,34 These approaches based on different reaction instruments were able to prepare KCC-1 effectively, whereas evident non-uniformity issue of nanosphere sizes has not been resolved yet. Fortunately, non-uniform size with large differences does not inuence KCC-1 applications like catalysis, 32,33 cancer and tumour therapy, 35,36 gene and protein delivery, 37 water treatment, 38,39 chromatography, 40,41 dye-sensitized solar cell and supercapacitor, 42,43 etc. For this reason, only limited attentions have been paid and few investigations have been conducted to ameliorate KCC-1 size uniformity.…”

“…By virtue of their native structural advantage, DMSNs are extensively used as a catalytic support for various chemical reactions 111,[138][139][140][141][142][143][144][145][146][147][148][149][150][151] and can be directly applied for efficient catalysis through introducing other active metal elements into the structure 77,122,128,152,153 or surface modication. [154][155][156][157][158] While the catalytic performance actually depends on many factors (such as the quantity, properties, micro-environment of the active site, etc.) and cannot be absolutely attributed to the advantage of the structure, it is still an ideal platform for the design of metal nanocluster (NC) based heterogeneous catalysts with high performance, because of the bimodal pore size distributions of DMSNs, especially the small open spherical mesopores which provide an ideal nanoreactor for the encapsulation of metal NCs of a size less than 3.0 nm.…”

The interest in the design and controlled fabrication of dendritic mesoporous silica nanospheres (DMSNs) emanates from their widespread application in drug-delivery carriers, catalysis and nanodevices owing to their unique open three-dimensional dendritic superstructures with large pore channels and highly accessible internal surface areas. A variety of synthesis strategies have been reported, but there is no basic consensus on the elucidation of the pore structure and the underlying formation mechanism of DMSNs. Although all the DMSNs show a certain degree of similarity in structure, do they follow the same synthesis mechanism? What are the exact pore structures of DMSNs? How did the bimodal pore size distributions kinetically evolve in the self-assembly? Can the relative fractions of small mesopores and dendritic large pores be precisely adjusted? In this review, by carefully analysing the structures and deeply understanding the formation mechanism of each reported DMSN and coupling this with our research results on this topic, we conclude that all the DMSNs indeed have the same mesostructures and follow the same dynamic self-assembly mechanism using microemulsion droplets as super templates in the early reaction stage, even without the oil phase.

Heterogeneous catalysis plays a key role in promoting green chemistry through many routes. The functionalizable reactive silanols highlight silica as a beguiling support for the preparation of heterogeneous catalysts. Metal active sites anchored on functionalized silica (FS) usually demonstrate the better dispersion and stability due to their firm chemical interaction with FSs. Having certain functional groups in structure, FSs can act as the useful catalysts for few organic reactions even without the need of metal active sites which are termed as the covetous reusable organocatalysts. Magnetic FSs have laid the platform where the effortless recovery of catalysts is realized just using an external magnet, resulting in the simplified reaction procedure. Using FSs of multiple functional groups, we can envisage the shortened reaction pathway and, reduced chemical uses and chemical wastes. Unstable bio‐molecules like enzymes have been stabilized when they get chemically anchored on FSs. The resultant solid bio‐catalysts exhibited very good reusability in many catalytic reactions. Getting provoked from the green chemistry aspects and benefits of FS‐based catalysts, we confer the recent literature and progress focusing on the significance of FSs in heterogeneous catalysis. This review covers the preparative methods, types and catalytic applications of FSs. A special emphasis is given to the metal‐free FS catalysts, multiple FS‐based catalysts and magnetic FSs. Through this review, we presume that the contribution of FSs to green chemistry can be well understood. The future perspective of FSs and the improvements still required for implementing FS‐based catalysts in practical applications have been narrated at the end of this review.
