Special Issue Information

Dear Colleagues,

Carbon nanomaterials gradually play crucial role in the green energy and catalysis research fields due to their the exceptional mechanical, electrical, and unique chemical features. On one way, the development of novel green energy storage systems has significantly contributed to the realization of environmentally friendly energy mix in recent years. Precise design and regulation of the microscopic morphology of carbon nanomaterials, as well as the in-depth study of the reaction mechanism, reaction thermodynamics, and reaction kinetics of green energy storage systems, are conducive to the construction of high-performance, long-lasting, and cost-effective green energy storage systems. On the other way, advanced catalysis technologies are equally serious and efficient methods for the production of new renewable and sustainable energy sources. The development of highly active catalysts with carbon nanomaterials has become a prominent topic of focus in catalytic technology. Specially, simulation of the catalyst model and the theoretical calculation of the catalytic reaction process can provide substantial support for the design and fabrication of a feasible catalyst structure.

In this Special Issue of Nanomaterials, we expect contributions from a wide community of researchers and scientists working on carbon nanomaterials (including graphene, carbon nanotubes, graphite, amorphous carbon and other carbon-based nanomaterials) relating to green energy storage applications, such as batteries, supercapacitors, hybrid supercapacitors, and emerging miniature energy storage devices, and catalysis applications, such as photocatalysts and electrocatalysts for water splitting, fuel cells, and metal-air batteries. Since diverse green energies (e.g., chemical energy, mechanical energy, solar energy, etc.) receive more and more attention in recent years, we also anticipate manuscripts dealing with these aspects in this Special Issue.

This study was carried out in order to assess several modifications of carbon nanotube-based nanomaterials for their applications in laccase electrodes and model biofuel cells. The modified MWCNTs served as adapters for the immobilization of laccase from Catenuloplanes japonicus VKM Ac-875 on the surface of electrodes made of graphite rods and graphite paste. The electrochemical properties of the electrodes were tested in linear and cyclic voltammetrical measurements for the determination of the redox potential of the enzyme and achievable current densities. The redox potential of the enzyme was above 500 mV versus NHE, while the highest current densities reached hundreds of µA/cm2. Model biofuel cells on the base of the laccase cathodes had maximal power values from 0.4 to 2 µW. The possibility of practical application of such BFCs was discussed. Full article

Developing electrocatalysts with high energy conversion efficiency is urgently needed. In this work, P-Fe3O4/Fe@C electrodes with rich under-coordinated Fe atom interfaces are constructed for efficient pH-universal water splitting. The introduction of under-coordinated Fe atoms into the P-Fe3O4/Fe@C interface can increase the local charge density and polarize the 3d orbital lone electrons, which promotes water adsorption and activation to release more H*, thus elevating electrocatalytic activity. As a donor-like catalyst, P-Fe3O4/Fe@C displays excellent electrocatalytic performance with overpotentials of 160 mV and 214 mV in acidic and alkaline electrolytes at 10 mA cm−2, in addition to pH-universal long-term stability.

Flexible sensing electronics have received extensive attention for their potential applications in wearable human health monitoring and care systems. Given that the normal physiological activities of the human body are primarily based on a relatively constant body temperature, real-time monitoring of body surface temperature using temperature sensors is one of the most intuitive and effective methods to understand physical conditions. With its outstanding electrical, mechanical, and thermal properties, graphene emerges as a promising candidate for the development of flexible and wearable temperature sensors. In this review, the recent progress of graphene-based wearable temperature sensors is summarized, including material preparation, working principle, performance index, classification, and related applications. Finally, the challenges and future research emphasis in this field are put forward. This review provides important guidance for designing novel and intelligent wearable temperature-sensing systems.

Water pollution is one of the most important problems in the field of environmental protection in the whole world, and organic pollution is a critical one for wastewater pollution problems. How to solve the problem effectively has triggered a common concern in the area of environmental protection nowadays. Around this problem, scientists have carried out a lot of research; due to the advantages of high efficiency, a lack of secondary pollution, and low cost, photocatalytic technology has attracted more and more attention. In the past, MnO2 was seldom used in the field of water pollution treatment due to its easy agglomeration and low catalytic activity at low temperatures. With the development of carbon materials, it was found that the composite of carbon materials and MnO2 could overcome the above defects, and the composite had good photocatalytic performance, and the research on the photocatalytic performance of MnO2-carbon materials has gradually become a research hotspot in recent years. This review covers recent progress on MnO2-carbon materials for photocatalytic water treatment. We focus on the preparation methods of MnO2 and different kinds of carbon material composites and the application of composite materials in the removal of phenolic compounds, antibiotics, organic dyes, and heavy metal ions in water. Finally, we present our perspective on the challenges and future research directions of MnO2-carbon materials in the field of environmental applications. Full article
