TopicsAdvanced Nanomaterials in Catalysis
Nanomaterials have revolutionized numerous fields, including biology, environmental science, agriculture, and healthcare. In catalysis, they offer enhanced selectivity, recyclability, and efficiency, while their unique properties have driven advances in sensing technologies for environmental monitoring and biomedical diagnostics. This themed collection highlights recent breakthroughs in these domains, demonstrating how nanomaterials bridge the gap between fundamental research and practical applications.
Tamtam et al. (https://doi.org/10.1039/D5NA00019J) synthesized bimetallic Cu/Co-MOFs using three synthetic approaches, demonstrating exceptional stability in asymmetric and symmetric coin cell devices. Complementing this, Weheabby et al. (https://doi.org/10.1039/D4NA00919C) advanced sensing technologies by developing an electrochemical sensor for methyl parathion detection, utilizing AgNPs@GO/IL@SPCE, achieving a detection limit of 0.009 μmol L^−1^ with excellent selectivity and stability over 60 days.
The role of nanomaterials in catalysis is further underscored by Nguyen et al. (https://doi.org/10.1039/D4NA00979G), who reported AuNP-embedded magnetic nanocomposites (AuNPs/Fe_3_O_4_@GluN/Alg) for nitrophenol reduction, exhibiting high catalytic efficiency and recyclability. Similarly, Tran et al. (https://doi.org/10.1039/D4NA00707G) explored PANI nanoparticles for visible-light-driven dye degradation, achieving 97.09% methylene blue removal with sustained photostability, highlighting the potential of nanomaterials in environmental remediation.
Expanding into sustainable energy applications, Nguyen et al. (https://doi.org/10.1039/D4NA00892H) developed a defect-rich CeO_x/β-Ni(OH)2 electrocatalyst for glucose oxidation-assisted hydrogen production, delivering nearly 100% faradaic efficiency. This aligns with the work of Conlin et al. (https://doi.org/10.1039/D4NA00854E), who investigated the stability of ALD-synthesized TiO_2 and ZnO films under CO_2_ plasma exposure, confirming their robustness for catalytic applications in carbon capture and conversion. Further advancing catalytic efficiency, Ta and Nhiem (https://doi.org/10.1039/D4NA00947A) designed Au single-atom catalysts on TiO_2_ for photocatalytic methane oxidation, achieving a hydrogen production rate of 2190 μmol g^−1^ and 58% selectivity via a methyl radical pathway, offering a promising route for methane valorization.
