Special Issue Information

Dear Colleagues,

Catalysis is an integral part of organic transformations including various catalytic areas such as homogeneous catalysis, graphene/carbon-based catalysts, single-atom catalysts, MOF-COF, integrated catalysts, core–shell catalysts, and other types of catalysts. Recent decades have seen a rapid advancement in technology, allowing the development of increasingly sustainable heterogeneous nanomaterials and catalysts. For example, catalytic materials can now be manufactured with greater precision via nanotech-enabled procedures. With well-defined sizes, structures, and compositions, metal/bimetallic nanoparticles, which frequently act as active catalytic components, can be made in a way that is more environmentally friendly.

Such controllability could potentially lead to advanced catalytic/photocatalytic/electrocatalytic technologies and their applications in sustainable processes. As well as the traditional need for efficient and selective catalytic reactions that will transform raw materials into valuable chemicals, pharmaceuticals, and fuels, sustainable chemistry also strives for waste reduction, atomic efficiency, and high rates of catalyst recovery. This Special Issue is aims to highlight key examples of sustainable nanomaterials with applications on various important catalytic/sustainable processes, including photocatalytic and electrocatalytic applications.

The present work reported a novel strategy to construct supported cationic-polystyrene-resin-bound silver nanocomposites for enhanced catalytic reduction of 4-nitrophenol in an aqueous medium. The Fourier transform infrared spectroscopy (FTIR) was used as a model instrument for the study of catalytic reduction of 4-nitrophenol using cationic-polystyrene-resin-bound silver nanocomposite materials. The mechanism is based on the reduction of 4-nitrophenol to 4-aminophenol due to the electron transfer process that occurred between donor borohydride (BH4) and acceptor 4-nitrophenol. The polystyrene resin provides support and surface area to increase the catalytic activity of silver nanoparticles. The diffused reflectance-Fourier transform infrared spectroscopy revealed the binding of silver particles onto the surface of cationic polystyrene resin beads. Furthermore, the catalyst was easily separated by the filtration and drying process and was able to reuse. A quantitative analysis of this work has also been performed. The linearity range, the limit of detection, and the limit of quantification obtained for the present method were 0.1 × 10−4 to 1.0 M, 0.6 M, and 2.1 M, respectively. Moreover, a good catalytic efficiency was found to be 96.8%. The advantages of the current method are its simplicity, sensitivity, rapidity, low cost, ease of preparation, and excellent catalytic efficiency to reduce 4-nitrophenol from an aqueous solution.
