Book Description
As an environmentally benign element, bismuth has found more and more applications in advanced materials. Our research is aimed at two aspects of bismuth oxide materials. Our goal is to provide precursors for bismuth oxide. Bismuth trioxide is an important component of many ferroelectric materials, but the development of bismuth precursors is still very limited. Another goal of our research is to synthesize homogenous model systems for the catalyst of the SOHIO process. In the SOHIO process, propene is selectively oxidized to acrolein or selectively ammoxidized to acrylonitrile. The detailed mechanism of the process remains controversial. Several molybdenum and Mo/Bi bimetallic systems have been studied, but no bismuth model has been reported before. In the second chapter, I reported the isolation and full characterization of twelve bismuth aryloxide complexes, Bi(OAr)3. The substituents' steric effect and electronic effects on the synthesis were studied. Phenyl substituents were utilized to study the bismuth-arene interactions. I also synthesized complexes with allyl or benzyl substituents very close to the bismuth center. These complexes can be good model systems to study the SOHIO process. The bismuth aryloxides we synthesized can also be used as sol-gel precursors for bismuth oxide materials. In the third chapter, I reported the synthesis of bismuth aryloxide amides Bi(OAr)n(NR)3-n, using a ligand exchange method (Bi(OAr)3 + Li(NR)---Bi(OAr)n(NR)3-n). The ligand exchange method is versatile for several kinds of bismuth aryloxide as well as an antimony aryloxide. The bismuth aryloxide amides were spectroscopically characterized, and four of them were characterized by X-ray diffraction. The bismuth aryloxide amides are also good precursors for Bi2O3 materials. They are volatile, light stable and low melting, with excellent solubility and tunable thermal stability. In the fourth chapter, I reported the isolation of ten monosubstituted alkali metal calix[8]arene complexes. Preliminary results were also obtained for reactions of the mono substituted alkali metallocalix[8]arenes with several kinds of bismuth compounds.

Book Description
Because of the great importance of acid catalysis in the petrochemical industry, extensive research has been carried out during the last 30 years concerning the fundamental and applied aspects of catalysis by acids. In contrast, base-catalyzed reactions have received little attention in heterogeneous catalysis. The aim of this symposium was to evaluate our knowledge of the important area of acid and base catalysis and to cover a broad range of solids, zeolite chemistry being only one aspect of heterogeneous catalysis.

Book Description
Unique state-of-the-art book on an important topic in renewable materials The purpose of this monograph is to provide a thorough outlook on the topic related to the synthesis and characterization of original macromolecular materials derived from plant oils, an important part of the broader steadily growing discipline of polymers from renewable resources. The interest in vegetable oils as sources of biodiesel and materials has witnessed a remarkable growth of scientific and industrial interest since the beginning of the third millennium responding to the pressing drive to implement sustainability in the energy and materials sectors. The book highlights the most relevant strategies being pursued to elaborate polymers derived from a variety of common oils, by direct activation or through chemical modifications yielding novel monomers. Because glycerol is the main byproduct of biodiesel production, it is treated here as the other logical source of macromolecular synthesis. Each of the different approaches is illustrated by an introductory layout of the underlying chemical mechanisms, followed by examples of notable achievements in terms of the properties and potential applications of the ensuing materials, which span a wide range of structures and performances. In particular, original pathways involving click-chemistry reactions as thiol-ene and Diels-Alder couplings and metathesis polymerizations are discussed and shown to reflect the involvement of a growing number of research programs worldwide.

Book Description
Photoelectrocatalysis: Fundamentals and Applications presents an in-depth review of the topic for students and researchersworking on photoelectrocatalysis-related subjects from pure chemistry to materials and environmental chemistry inorder to propose applications and new perspectives. The main advantage of a photoelectrocatalytic process is the mildexperimental conditions under which the reactions are carried out, which are often possible at atmospheric pressure androom temperature using cheap and nontoxic solvents (e.g., water), oxidants (e.g., O2 from the air), catalytic materials (e.g.,TiO2 on Ti layer), and the potential exploitation of solar light. This book presents the fundamentals and the applications of photoelectrocatalysis, such as hydrogen production fromwater splitting, the remediation of harmful compounds, and CO2 reduction. Photoelectrocatalytic reactors and lightsources, in addition to kinetic aspects, are presented along with an exploration of the relationship between photocatalysisand electrocatalysis. In addition, photocorrosion issues and the application of selective photoelectrocatalytic organictransformations, which is now a growing field of research, are also reported. Finally, the advantages/disadvantages andfuture perspectives of photoelectrocatalysis are highlighted through the possibility of working at a pilot/industrial scale inenvironmentally friendly conditions. Presents the fundamentals of photoelectrocatalysis Outlines photoelectrocatalytic green chemistry Reviews photoelectrocatalytic remediation of harmful compounds, hydrogen production, and CO2 reduction Includes photocorrosion, photoelectrocatalytic reactors, and modeling along with kinetic aspects
