Special Issue Information

Dear Colleagues,

For modern science and technology, catalysis is an advanced technology widely utilized in various areas such as chemistry, chemical engineering, materials science, energy and environmental sciences. To date, numerous catalysts, either homogenous (e.g., metal salts, organometallic complexes amd organocatalysts) or heterogenous (e.g., ordered porous materials, composite materials, semiconductors, metal oxides and perovskites) ones, have been rapidly developed and applied to all these fields. In particular, the research and development of numerous catalytic strategies on the preparation of bioactive molecules such as natural products, pharmaceuticals, pesticides and valuable lead compounds are of vital importance. On the other hand, small molecules (e.g., CO2, H2O and N2O) can be activated by catalysts to afford a wide variety of environment and energy-related chemicals (e.g., methanol, methane, ethanol, dihydrogen gas and nitrogen gas) and value-added chemicals (e.g., organic carbonates and biomass-derived compounds). Thus, this Special Issue aims to provide a platform for researchers and engineers to discuss versatile strategies for bioactive compound synthesis and small molecule activation via thermal catalysis, photocatalysis and/or electrocatalysis.

In this study, oxidized maltodextrins with a high concentration of carboxyl groups were produced using CuSO4 as a catalyst and H2O2 as an eco-friendly oxidant. Infrared spectroscopy, proton-nuclear magnetic resonance spectroscopy, and thermogravimetric analysis were utilized to examine the structure and properties of oxidized maltodextrins. The reaction conditions were optimized in terms of oxidant content, catalyst content, temperature, pH, and reaction time. The prepared oxidized maltodextrin had a carboxyl group content of 105% under the conditions of 200% molar H2O2, 1% molar catalyst, 55 °C, initial pH = 9.7, and 2 h reaction time. In comparison to the commonly used sodium hypochlorite oxidation process, the carboxyl group content was increased by 58%. Full article

The formation of valuable chiral skeletons through asymmetric gold catalysis has made considerable progress due to the unrivaled affinity of gold complexes with multiple carbon–carbon bonds. The renaissance of chiral ligands in recent decades has enabled the elaborate design of chiral gold complexes, which are of great significance to control chiral formation in these catalytic reactions. Therefore, this review intends to highlight the design and central role of versatile chiral ligands in asymmetric gold catalysis. Specifically, the seminal applications of various chiral ligands with representative examples in various gold-catalyzed asymmetric reactions are comprehensively explored. In addition, the reaction mechanisms are mentioned when the crucial interactions between ligands and activated substrates are introduced. Furthermore, the applications of enantioselective gold catalysis in the construction of chiral functional organic materials and drug molecules are also presented. Full article

Nitrous oxide (N2O) is an environmental pollutant that has a significant greenhouse effect and contributes to the depletion of the ozone layer. To address the issues caused by N2O, direct catalytic decomposition of N2O to N2 and O2 has been demonstrated as one of the most efficient methods for its removal. Various metals, particularly noble metals, including Rh, Ru, Pd, Pt, Au, and Ir, have been widely used and investigated as catalysts to facilitate this transformation. Therefore, this review aims to provide an overview of the advances in noble metal-based catalysts studied in recent years. The comprehensive discussion includes the influence of multiple factors, such as catalyst supports, preparation methods, additives, and impurity gases (such as O2, H2O, SO2, NO, and CO2) on the performance of versatile catalysts. Furthermore, this review offers insights into the future trends of catalyst systems for the direct catalytic decomposition of N2O. Full article
