“…The chemical conversion of CuO to Cu 2 S during H 2 S sensing is responsible for the enhanced gas sensing. Recently we prepared large scale Ag 2 O/Zn 2 SnO 4 hybrid periodic nanowires at 650°C by using a unique one-step silver oxide catalyzed vapor-solid-solid (VSS) growth process and the ethanol sensing property was investigated (Cai et al, 2010 ). Figure 7 presents the sensor configuration and ethanol sensing performance of the hybrid periodic nanowires.…”

This review presents a comprehensive overview of the hierarchical nanostructured materials with either geometry or composition complexity in environmental applications. The hierarchical nanostructures offer advantages of high surface area, synergistic interactions, and multiple functionalities toward water remediation, biosensing, environmental gas sensing and monitoring as well as catalytic gas treatment. Recent advances in synthetic strategies for various hierarchical morphologies such as hollow spheres and urchin-shaped architectures have been reviewed. In addition to the chemical synthesis, the physical mechanisms associated with the materials design and device fabrication have been discussed for each specific application. The development and application of hierarchical complex perovskite oxide nanostructures have also been introduced in photocatalytic water remediation, gas sensing, and catalytic converter. Hierarchical nanostructures will open up many possibilities for materials design and device fabrication in environmental chemistry and technology.

Composite nanoarchitectures represent a class of nanostructured entities that integrates various dissimilar nanoscale building blocks including nanoparticles, nanowires, and nanofilms toward realizing multifunctional characteristics. A broad array of composite nanoarchitectures can be designed and fabricated, involving generic materials such as metal, ceramics, and polymers in nanoscale form. In this review, we will highlight the latest progress on composite nanostructures in our research group, particularly on various metal oxides including binary semiconductors, ABO3-type perovskites, A2BO4 spinels and quaternary dielectric hydroxyl metal oxides (AB(OH)6) with diverse application potential. Through a generic template strategy in conjunction with various synthetic approaches— such as hydrothermal decomposition, colloidal deposition, physical sputtering, thermal decomposition and thermal oxidation, semiconductor oxide alloy nanowires, metal oxide/perovskite (spinel) composite nanowires, stannate based nanocompostes, as well as semiconductor heterojunction—arrays and networks have been self-assembled in large scale and are being developed as promising classes of composite nanoarchitectures, which may open a new array of advanced nanotechnologies in solid state lighting, solar absorption, photocatalysis and battery, auto-emission control, and chemical sensing.

“…Organic–inorganic hybrid materials are recognized as a new class of advanced materials because of the versatile synthetic approaches used for their synthesis as well as the molecular tailing properties involved with it [1, 2]. In the past few years, organic–inorganic hybrid materials have drawn a lot of attention because of their superior optical properties [3], mechanical properties [4], rheological properties [5], catalytic properties [6], and fire retardancy [7].…”

A comparative study on the preparation and physical properties of environmental friendly PMMA‐silica nano/sub‐micron‐scale hybrid latexes controlled by chelating agent

In this article, a comparative study of the preparation and physical properties of as‐prepared PMMA‐silica nano‐hybrid (PSN) and sub‐micro‐hybrid (PSM) latexes is successfully presented. Vinyl‐modified silica spheres were prepared using the Stöber process with/without a chelating agent to control particle size. The as‐prepared vinyl‐modified silica spheres with different particle sizes were subsequently characterized by SEM, 13C‐solid‐state NMR, and 29Si‐solid‐state NMR spectroscopy. A certain feeding amount of silica spheres was reacted with MMA monomers by emulsion polymerization to yield a series of PSN and corresponding PSM. Both as‐prepared nano/sub‐micronscale hybrid materials were further characterized by FTIR, SEM‐EDX mapping, and TEM studies. The comparative study on the physical properties of both as‐prepared nano/sub‐micron‐scale hybrid materials was done systematically based on a series of instrumentation evaluations performed using a dynamic mechanical analyzer, electrochemical corrosion measurements, salt spray test, and gas permeability analysis. Results indicated that PSN has more effectively enhanced mechanical properties, corrosion protection properties, as well as gas barrier compared to PSM. POLYM.
