Special Issue Information

Dear Colleagues,

The production and consumption of traditional energy sources have, until now, had significant impacts on climate change, global warming, and the treatment of various waste products. In light of this, to mitigate the use of fossil fuels and cater to the growing energy demands, there is an imperative need to develop techniques for green energy collection and high-performance energy technologies in the hopes of achieving zero emissions. These technologies ought to be grounded either in recycling practices or the innovative development of novel functional materials.

Regarding materials, conventional ones often face limitations due to their confined efficiency and performance, limited durability and availability, as well as potential environmental repercussions and high material costs. Consequently, in the coming years, the concept of sustainable materials and techniques will gain increasing prominence in efforts to diminish environmental impacts.

We cordially invite you to submit your research findings to our Special Issue entitled "Multifunctional Nanomaterials for Energy: Synthesis, Characteristics, and Applications" in the journal Processes.

The objective of this Special Issue is to encompass the latest research in the domain of multifunctional nanomaterials for energy applications. This encompasses the synthesis processes of nanomaterials, their characteristics, their properties pertaining to specific energy forms, and their applications. The source materials could range from semiconductors, carbon, and composites to other materials applicable in the energy sector. Thus, this Special Issue will particularly emphasize solutions provided by new types of nanomaterials and the judicious use of alternative materials at a smaller scale to enhance the efficiency of energy generation or collection.

This study investigates the impact of plasma gradient modification and gradient illumination on the optoelectronic properties of buckypaper (BP), a flexible and large-scale material composed of multi-walled carbon nanotubes (MWCNTs). The BP samples were subjected to argon ion plasma treatment at varying power levels and durations, thereby creating different carrier concentration gradients on the surface. The photovoltage and photocurrent responses of the samples were then measured under uniform full illumination and gradient illumination conditions. The findings revealed that both plasma gradient modification and gradient illumination significantly enhanced the optoelectronic performance of BP. Notably, the combined application of these two methods yielded superior results compared to the application of either method alone. Specifically, the optimal plasma power for improving BP was found to be 20 W. Under conditions of plasma gradient modification and gradient illumination, a photovoltage of 267.76 μV was generated, which represents a 21.44 times increase, and a photocurrent of 15.69 μA, reflecting a 32.69 times enhancement. The mechanism underlying this optoelectronic effect can be attributed to the presence of π-bonds in the carbon atoms. These π-bonds are excited by photons, resulting in the generation of small voltages and currents. This study underscores the potential of BP as an optoelectronic material and introduces a novel approach to enhance its optoelectronic properties through plasma gradient modification and gradient illumination.
