Special Issue Information

Dear Colleagues,

Nanomaterials offer greatly improved ionic transport and electronic conductivity and enable the occupation of all intercalation sites available in the particle volume, leading to high specific capacities and fast ion diffusion. Nanomaterial-based electrodes are capable of withstanding high currents, offering a promising solution for high-energy and high-power energy storage. The development of nanomaterials and their related processing into electrodes and devices can improve the performance and/or development of the existing energy storage systems, catalytic adsorption applications and solve the environmental issues. Nanostructuring is becoming key in controlling electrochemical performance and exploiting various charge storage mechanisms, such as surface-based ion adsorption, reversion faradic reactions, and diffusion-limited intercalation processes. There are several underlying factors, such as multiple root causes of pollution, including industrialization and poor electrode performances (lack of improved ionic transport and electronic conductivity) that limit the uses of nanomaterials in energy technology, environmental remediation and catalytic processes. Thus, improvement of nanomaterials and processing is essential to address this challenging issue.

This Special Issue will provide a concise reference on the synthesis and processing of nanomaterials for the next generation of devices used in renewable energy, conversion and storage, environmental remediation and catalytic applications. The Special Issue will report the synthesis and processing of bio-organic materials, environmentally friendly organic and inorganic sources of materials, synthetic green chemistry, metal oxides, and the concept of sustainable material design for energy technology, in an attempt to address the current environmental issues and limited catalytic applications.

I am looking forward to your contribution!

Abstract
Active photocatalysts with an efficiency of 99% were prepared for the degradation of the industrial dye, methylene blue (MB), under visible light irradiation. These photocatalysts comprised Co/Ni-metal–organic frameworks (MOFs), to which bismuth oxyiodide (BiOI) was added as a filler to prepare Co/Ni-MOF@BiOI composites. [...] Read more.
Active photocatalysts with an efficiency of 99% were prepared for the degradation of the industrial dye, methylene blue (MB), under visible light irradiation. These photocatalysts comprised Co/Ni-metal–organic frameworks (MOFs), to which bismuth oxyiodide (BiOI) was added as a filler to prepare Co/Ni-MOF@BiOI composites. The composites exhibited remarkable photocatalytic degradation of MB in aqueous solutions. The effects of various parameters, including the pH, reaction time, catalyst dose, and MB concentration, on the photocatalytic activity of the prepared catalysts were also evaluated. We believe that these composites are promising photocatalysts for the removal of MB from aqueous solutions under visible light. Full article

Textile-based Joule heaters in combination with multifunctional materials, fabrication tactics, and optimized designs have changed the paradigm of futuristic intelligent clothing systems, particularly in the automobile field. In the design of heating systems integrated into a car seat, conductive coatings via 3D printing are expected to have further benefits over conventional rigid electrical elements such as a tailored shape and increased comfort, feasibility, stretchability, and compactness. In this regard, we report on a novel heating technique for car seat fabrics based on the use of smart conductive coatings. For easier processes and integration, an extrusion 3D printer is employed to achieve multilayered thin films coated on the surface of the fabric substrate. The developed heater device consists of two principal copper electrodes (so-called power buses) and three identical heating resistors made of carbon composites. Connections between the copper power bus and the carbon resistors are made by means of sub-divide the electrodes, which is critical for electrical–thermal coupling. Finite element models (FEM) are developed to predict the heating behavior of the tested substrates under different designs. It is pointed out that the most optimized design solves important drawbacks of the initial design in terms of temperature regularity and overheating. Full characterizations of the electrical and thermal properties, together with morphological analyses via SEM images, are conducted on different coated samples, making it possible to identify the relevant physical parameters of the materials as well as confirm the printing quality. It is discovered through a combination of FEM and experimental evaluations that the printed coating patterns have a crucial impact on the energy conversion and heating performance. Our first prototype, thanks to many design optimizations, entirely meets the specifications required by the automobile industry. Accordingly, multifunctional materials together with printing technology could offer an efficient heating method for the smart textile industry with significantly improved comfort for both the designer and user.
