The superior photocatalytic activities of Au@TiO 2 core‐shell nanocrystals can be ascribed to the enhanced light harvesting that is enabled by the localized surface plasmon resonance of the Au core and the built‐in internal electric field.…”

Inorganic nanocrystals possess unique physicochemical properties compared to their bulk counterparts. Stabilizing agents are commonly used for the preparation of inorganic nanocrystals with controllable properties. Particularly, colloidal polymers have emerged as general and robust templates for in situ formation and confinement of inorganic nanocrystals. In addition to templating and stabilizing inorganic nanocrystals, colloidal polymers can tailor their physicochemical properties such as size, shape, structure, composition, surface chemistry, and so on. By incorporating functional groups into colloidal polymers, desired functions can be integrated with inorganic nanocrystals, advancing their potential applications. Here, recent advances in the colloidal polymer‐templated formation of inorganic nanocrystals are reviewed. Seven types of colloidal polymers, including dendrimer, polymer micelle, stare‐like block polymer, bottlebrush polymer, spherical polyelectrolyte brush, microgel, and single‐chain nanoparticle, have been extensively applied for the synthesis of inorganic nanocrystals. Different strategies for the development of these colloidal polymer‐templated inorganic nanocrystals are summarized. Then, their emerging applications in the fields of catalysis, biomedicine, solar cells, sensing, light‐emitting diodes, and lithium‐ion batteries are highlighted. Last, the remaining issues and future directions are discussed. This review will stimulate the development and application of colloidal polymer‐templated inorganic nanocrystals.

“…To replace the expensive noble metal nanoparticles, several semiconductors such as MoS 2 , TiO 2 , CdS, and Cu 2 O were also incorporated into microgel systems to degrade 4-nitrophenol, pendimethalin, rhodamine B, and methyl orange. Specifically, Cu 2 O/PNIPAm hybrid microgels were prepared with a Cu 2 O nanocube as the core and a PNIPAm polymeric network as the shell to remove dyes from water .…”

To overcome the current scarcity of fresh water sustainably, new technologies will be required that produce potable water from a range of sources, including seawater and moisture from the atmosphere. Moreover, we must recover and reuse water from wastewater streams to reduce our global water footprint. To date, there remain significant concerns about the environmental/ecological impact, high energy consumption, and extensive maintenance costs of current technologies that might prevent their transition to more sustainable routes of potable water generation. One class of material that can enable low-energy water production is thermoresponsive polymers. Due to their unique phase behavior, production flexibility, and biocompatibility, these materials may allow for sustainable routes to fresh water in current and new technologies. In this Perspective, we specifically summarize the design and application of poly(N-isopropylacrylamide)-(PNIPAm-) based thermoresponsive microgels and hydrogels. In particular, we show how these materials have been used for water purification, including wastewater treatment, seawater desalination, and moisture harvesting from the atmosphere. Finally, we discuss the opportunities and challenges of transforming current thermoresponsive materials into practical water-related technologies.

“…However, despite the fact that this possibility was recognized quite early, the examples of application of this strategy to the production of hybrid colloids containing an inorganic component different from noble metals have remained quite limited. In particular, whereas some examples exist in the generation of metal chalcogenide NPs (quantum dots) within microgels, − the possibility to generate inorganic oxides has been largely overlooked, apart from studies concerning iron oxides, − silica, − or zinc oxide , as the inorganic component. With this work, we contribute to fill this gap by investigating the generation of metal oxides within microgels, with the aim of using them as nanostructured supports for metal NPs cogenerated within the same microgel.…”

An approach for the preparation of noble metal nanoparticles supported on nanostructured metal oxides is described herein. The approach is based on the sequential generation of the noble metal nanoparticles and of a metal oxide phase inside a cross-linked polymer colloid (microgel). By tuning the properties of the employed microgel, the nature and amount of both the noble metal nanoparticles and the metal oxide phase can be independently varied. The resulting composite colloids are colloidally stable and, upon isolation by precipitation and subsequent calcination, produce noble metal nanoparticles dispersed on a crystalline, nanostructured oxide phase. Preliminary catalytic tests provide information on the accessibility of the noble metal nanoparticles and, particularly in the case of gold, result in promising catalytic performances in the aerobic oxidation of alcohols.

Synthesis of poly (N-isopropylacrylamide)-co-(acrylic acid) microgel-entrapped CdS quantum dots and their photocatalytic degradation of an organic dye

Abstract: CdS quantum dots (CdSQDs) were generated inside the network structure of poly (N-isopropylacrylamide)-co-(acrylic acid) (pNIPAm-co-AAc) microgels and their ability to photocatalytically degrade organic dyes was evaluated using rhodamine B (RhB).
