The scope of “Green Chemistry” focuses on a set of principles that minimize or eliminate the use or generation of hazardous substances in the design of processes, manufacturing techniques, and applications of chemical products aiming to respect the environment. One of most important principles is “prevention”, related to the reduction of coproduced wastes with respect to the desired product. Atom economy, saving energy, using renewable raw feedstocks and smart catalysts are other key principles of the processes in Green Chemistry. Moreover, the synthetic methods, chemicals and solvents in a process should preserve the efficacy of function while possessing minimum toxicity to human health and the environment. Considering the significant role of hazardous materials characterization in human health, further development of analytical methodologies to allow real-time, in-process monitoring and control before the formation of hazardous substances can improve Green Chemistry. Therefore, this Special Issue plans to give an overview and provide selected contributions on advances in the synthesis, characterization, and applications of materials in Green Chemistry. Coverage includes, but is not limited to, the following topics based on Green Chemistry: synthesis of catalysts; catalytic reactions; conversion of renewable feedstocks to valuable chemicals; synthesis of adsorbents; removal of pollutants; and materials and methods for the characterization of hazardous substances
