Special Issue Information

Dear Colleagues,

Energy is an important physical base for the development of humanity, the economy, and society. Energy conversion and storage are the key for energy development. The conversion between different energies, such as photoelectric conversion, thermoelectric conversion, and electro-optic conversion, plays an important role in the utilization of renewable energy. Solar cells, photocatalysis, hydrogen production by electrolysis of water, fuel cells, temperature difference cells, light-emitting diodes, etc., are all important energy conversion technologies. The storage of energy holds great significance in the context of the current world energy crisis. Therefore, the R&D of new materials and high-efficiency devices for energy conversion and storage have attracted increasing attention from global researchers and industries.

Nanostructured materials have received tremendous interest due to their unique mechanical/electrical properties and overall behavior contributed by the complex synergy of bulk and interfacial properties for efficient and effective energy conversion and storage.

Aimed at summarizing the recent research progress and establishing an exchange platform in the field of nanostructured new energy materials and devices, Nanomaterials and experts in this field have co-organized this Special Issue on Nanostructured New Energy Materials and Devices.

Abstract
This work investigates the optimization of carbon-based electrodes employed in bio-electrochemical systems (BES) through the deposition of nanostructured layers of poly(3,4-ethylene-dioxy-thiophene) poly(styrene-sulfonate) (PEDOT:PSS) on commercial carbon paper electrodes via ultrasonic spray coating (USC).

This work investigates the optimization of carbon-based electrodes employed in bio-electrochemical systems (BES) through the deposition of nanostructured layers of poly(3,4-ethylene-dioxy-thiophene) poly(styrene-sulfonate) (PEDOT:PSS) on commercial carbon paper electrodes via ultrasonic spray coating (USC). This innovative application of USC demonstrated that uniform and controlled depositions of PEDOT:PSS can be successfully performed on carbon-based electrodes. To this end, the morphology and spatial uniformity of depositions were verified via scanning electron microscopy and Raman spectroscopy. Electrochemical characterizations of fabricated electrodes demonstrated a more than two-fold increase in the electrochemical active surface area with respect to bare carbon paper. A lab-scale experiment on BES was performed, selecting microbial fuel cells (MFCs) as the reference devices. Devices featuring USC-deposited PEDOT:PSS electrodes showed a three-fold-higher energy recovery with respect to control cells, reaching a maximum value of (13 ± 2) J·m−3. Furthermore, the amount of PEDOT:PSS required to optimize MFCs’ performance is in line with values reported in the literature for other deposition methods. In conclusion, this work demonstrates that USC is a promising technique for application in BES. Full article
