Special Issue Information

Dear Colleagues,

This Special Issue is a continuation of a previous Special Issue, “Advances in Heterogeneous Catalysis in Nanochemistry”.

Heterogeneous catalysis has played an important role in the development of more sustainable chemistry for many research areas, as well as for the chemical industry, where many processes involve catalysts. Hence, any single advance in the field of catalysis, including the development of novel catalytic materials, catalyst synthesis strategies, and sustainable catalytic processes, may have a considerable impact on societal progress and will ensure a greener environment for forthcoming generations, addressing global energy and environmental challenges.

The unique synergy between surface chemistry and nanostructure has led to many exciting developments in the field of heterogeneous catalysis, gradually becoming the hotspot of materials science and promising to revolutionize chemical manufacturing. The aim of this Special Issue is to cover promising recent research and novel trends in heterogeneous catalysis employing various nanostructured materials for extensive applications in the fields of thermal catalysis, photocatalysis, electrocatalysis, photoelectrocatalysis, biocatalysis, etc., in research areas ranging from environmental remediation to organic transformations and renewable energy. Submissions are welcome in the form of original research manuscripts or critical review papers that represent the scientific field.

The design of metal–organic frameworks (MOFs) allows the definition of properties for their final application in small-scale heterogeneous catalysis. Incorporating various catalytic centers within a single structure can produce a synergistic effect, which is particularly intriguing for cross-coupling reactions. The URJC-1 material exhibits catalytic duality: the metal centers act as Lewis acid centers, while the nitrogen atoms of the organic ligand must behave as basic centers. The impact of reaction temperature, catalyst concentration, and basic agent concentration was evaluated. Several copper-based catalysts, including homogeneous and heterogeneous MOF catalysts with and without the presence of nitrogen atoms in the organic ligand, were assessed for their catalytic effect under optimal conditions. Among the catalysts tested, URJC-1 exhibited the highest catalytic activity, achieving complete conversion of 4-nitrobenzaldehyde with only 3% mol copper concentration in one hour. Furthermore, URJC-1 maintained its crystalline structure even after five reaction cycles, demonstrating remarkable stability in the reaction medium. The study also examined the impact of various substituents of the substrate alcohol on the reaction using URJC-1. The results showed that the reaction had high activity when activating substituents were present and for most cyclic alcohols rather than linear ones. Full article

The composites of heteropolyacids (H3PW12, H3PMo12) incorporated into amine-functionalized silica materials were used for the first time as heterogeneous catalysts in the valorization of glycerol (a major waste from the biodiesel industry) through acetalization reaction with acetone. The polyoxotungstate catalyst H3PW12@AptesSBA-15 exhibited higher catalytic efficiency than the phosphomolybdate, achieving 97% conversion and 97% of solketal selectivity, after 60 min at 25 °C, or 91% glycerol conversion and the same selectivity, after 5 min, performing the reaction at 60 °C. A correlation between catalytic performance and catalyst acidity is presented here. Furthermore, the stability of the solid catalyst was investigated and discussed. Full article

Zinc oxide (ZnO), a cheap, abundant, biocompatible, and wide band gap semiconductor material with easy tunable morphologies and properties, makes it one of the mostly studied metal oxides in the area of materials science, physics, chemistry, biochemistry, and solid-state electronics. Its versatility, easy bandgap engineering with transitional and rare earth metals, as well as the diverse nanomorphology empower ZnO as a promising photocatalyst. The use of ZnO as a functional material is attracting increased attention both for academia and industry, especially under the current energy paradigm shift toward clean and renewable sources. Extensive work has been performed in recent years using ZnO as an active component for different photocatalytic applications. Therefore, a thorough and timely review of the process is necessary. The aim of this review is to provide a general summary of the current state of ZnO nanostructures, synthesis strategies, and modification approaches, with the main application focus on varied photocatalysis applications, serving as an introduction, a reference, and an inspiration for future research.
