Book Description
The techniques and methods that can be applied to materials characterization on the microscale are numerous and well-established. Divided into two parts, Characterization of Nanostructures provides thumbnail sketches of the most widely used techniques and methods that apply to nanostructures, and discusses typical applications to single nanoscale objects, as well as to ensembles of such objects. Section I: Techniques and Methods overviews the physical principles of the main techniques and describes those operational modes that are most relevant to nanoscale characterization. It provides sufficient technical detail so that readers and prospective users can gain an appreciation of the strengths and limitations of particular techniques. The section covers both mainstream and less commonly used techniques. Section II: Applications of Techniques to Structures of Different Dimensionalities and Functionalities deals with the methods for materials characterization of generic types of systems, using carefully chosen illustrations from the literature. Each chapter begins with a brief description of the materials and supplies a context for the methods for characterization. The volume concludes with a series of flow charts and brief descriptions of tactical issues. The authors focus on the needs of the research laboratory but also address those of quality control, industrial troubleshooting, and online analysis. Characterization of Nanostructures describes those techniques and their operational modes that are most relevant to nanoscale characterization. It is especially relevant to systems of different dimensionalities and functionalities. The book builds a bridge between generalists, who play vital roles in the post-disciplinary area of nanotechnology, and specialists, who view themselves as more in the context of the discipline.

Book Description
Fe-ZnO catalysts were synthesized by impregnation technique and used to test the photocatalytic degradation of 2,4-DCP under visible light. Catalyst characteristic mainly presented wurtzite structure of ZnO, with crystalline size of 35-40 nm and 5-10 m2g−1 of specific surface area. Visible absorption of Fe-ZnO catalyst increased proportionally with Fe content. Oxidation state of Fe on ZnO surface was +3 and zero point charge was found at pH 9.5. Degradation experimental following Box-Behnken analysis provided an optimal condition of 2,4-DCP (initial concentration: 5.0 mg L−1) degradation under visible light at 5.0 mol% Fe-ZnO calcined at 700, and catalyst loading of 1.5 g L−1 (volume of synthetic waste water). Besides, the addition of 2 mM potassium persulfate (K2S2O8) could increase the degradation efficiency and the reaction could be completed within 90 min. The degradation performance on Fe-ZnO combined with K2S2O8 was 5 times higher than that using ZnO combined with K2S2O8. Reaction kinetics was fitted very well with the Langmuir-Hinshelwood model.

Book Description
The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use
