Special Issue Information

Dear Colleagues,

This Special Issue on Hard and Soft Hybrid Functional Materials will offer an attractive forum to present recent results concerning the preparation and characterization of novel functional hybrid materials and their utilization to perform innovative processes. “Soft” matter science can be considered as an interdisciplinary area, bridging chemistry, physics, biology and materials science and engineering. A variety of liquids can be included in the area of the soft materials: colloids; polymers; organic and metal organic films; liquid crystals; vesicles; and a number of biological materials. On the other hand, condensed matter and materials physics seeks to understand the diverse and often unexpected phenomena that emerge when large numbers of constituents are brought together to form macroscopic matter. "Hard" condensed matter generally deals with materials with structural rigidity, such as crystalline solids; glasses; metals; insulators; and semiconductors and includes inorganic; non-metallic; crystalline oxide; nitride; carbon or silica based materials. Considering the variety of combinations of hard and soft hybrid components, and related properties, the preparation and utility of novel intriguing classes of multipurpose materials can be presented in the form of reviews, regular research papers and short communications in this Special Issue.

Herein, we described the synthesis of a novel ion-imprinted membrane for the detection of palladium(II) prepared through the glutaraldehyde crosslinking of chitosan with a 4-[(4-Hydroxy)phenylazo]benzenesulfonic acid ligand trapped into the membrane. The imprinting technology was used to improve adsorption capacity and adsorption selectivity, and was combined with some advantages of the developed membrane, such as low cost and ease of preparation, water-friendly synthesis, and high biocompatible chitosan material. The membranes were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectrometry (EDS). The results obtained showed a high swelling ratio with a maximum value of 16.4 (1640%) at pH 4 with a strong pH dependence. Batch rebinding experiments gave a maximum adsorption capacity of 101.6 mg of Pd(II) per gram of imprinted membrane. The Pd(II) adsorption behavior was well-described by a Langmuir model with a theoretical maximum adsorption capacity of 93.48 mg g−1, similar to the experimental one. Finally, a selectivity study versus Ag(I), Pb(II), and Fe(III) ions demonstrated a good selectivity of chitosan-imprinted membrane towards Pd(II). Full article

This work describes the synthesis, characterization, and photocatalytic activity of new composite nanomaterials based on ZnO nanostructures impregnated by lipophlilic porphyrins derived from cashew nut shell liquid (CNSL). The obtained nanomaterials were characterized by X-ray diffraction (XRD), UV-Vis diffuse reflectance spectroscopy (DRS), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and steady-state photoluminescence spectra (PL). The results confirm nanostructures showing average diameter of 55 nm and an improved absorption in the visible region. Further, the FTIR analysis proved the existence of non-covalent interactions between the porphyrin molecules and ZnO. The photocatalytic activity of prepared photocatalysts was investigated by degradation of rhodamine B (RhB) in aqueous solution under visible light irradiation and natural sunlight. It was demonstrated that the photocatalytic activity increases in the presence of the porphyrins and, also, depends on the irradiation source. The development of composite photocatalysts based on porphyrins derived from CNSL provides an alternative approach to eliminate efficiently toxic wastes from water under ambient conditions.
