Special Issue Information

Dear Colleagues,

Under the background of the international Climate Conference, advocating energy conservation and emission reduction as well as the reduction of greenhouse gas emissions, the recycling of carbon dioxide is considered to be a top priority and urgent task. The reduction and utilization of carbon dioxide cannot be separated from the continuous research of materials chemistry. In order to assist and promote the research and development of materials in this field, we have organized this Special Issue, hoping to promote your scientific research investment in this field and the wide impact of the results. This Special Issue would like to receive the latest work on CO2 reduction and utilization.

At present, it is urgent to control the greenhouse effect. This Special Issue was organized to promote the recycling of carbon dioxide from the perspective of new material research and development, and highlight the importance of material research and development in the field of environmental science.

We are pleased to invite you to publish your latest research results in this Special Issue. It publishes reviews, regular research papers, communications, and short notes that are relevant to CO2 reduction of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis of nanomaterials with CO2 capture and transformation activity, application technology and application scale of this kind of nanomaterials. It is hoped that the collected works will cover material chemistry and material physics, and promote more effective transformation and utilization of CO2 through the development of material science. Your submission will be processed as quickly as possible.

This Special Issue aims to discover the most effective materials, improve the performance of existing materials, explain the working mechanism of materials as yet ununderstood, and computer aided efficient material design. In this Special Issue, original research articles and reviews are welcome.

We look forward to receiving your contributions.

Silicon carbide (SiC) is recognized as excellent material for high power/temperature applications with a wide-band gap semiconductor. With different structures at the nanosize scale, SiC nanomaterials offer outstanding mechanical, physical, and chemical properties leading to a variety of applications. In this work, new 3D pillared SiC nanostructures have been designed and investigated based on self-consistent charge density functional tight-binding (SCC-DFTB) including Van der Waals dispersion corrections. The structural and electronic properties of 3D pillared SiC nanostructures with effects of diameters and pillar lengths have been studied and compared with 3D pillared graphene nanostructures. The permeability of small gas molecules including H2O, CO2, N2, NO, O2, and NO2 have been demonstrated with different orientations into the 3D pillared SiC nanostructures. The promising candidate of 3D pillared SiC nanostructures for gas molecule separation application at room temperature is highlighted. Full article

The continual rise of the CO2 concentration in the Earth’s atmosphere is the foremost reason for environmental concerns such as global warming, ocean acidification, rising sea levels, and the extinction of various species. The electrochemical CO2 reduction (CO2RR) is a promising green and efficient approach for converting CO2 to high-value-added products such as alcohols, acids, and chemicals. Developing efficient and low-cost electrocatalysts is the main barrier to scaling up CO2RR for large-scale applications. Heteroatom-doped porous carbon-based (HA-PCs) catalysts are deemed as green, efficient, low-cost, and durable electrocatalysts for the CO2RR due to their great physiochemical and catalytic merits (i.e., great surface area, electrical conductivity, rich electrical density, active sites, inferior H2 evolution activity, tailorable structures, and chemical–physical–thermal stability). They are also easily synthesized in a high yield from inexpensive and earth-abundant resources that meet sustainability and large-scale requirements. This review emphasizes the rational synthesis of HA-PCs for the CO2RR rooting from the engineering methods of HA-PCs to the effect of mono, binary, and ternary dopants (i.e., N, S, F, or B) on the CO2RR activity and durability. The effect of CO2 on the environment and human health, in addition to the recent advances in CO2RR fundamental pathways and mechanisms, are also discussed. Finally, the evolving challenges and future perspectives on the development of heteroatom-doped porous carbon-based nanocatalysts for the CO2RR are underlined. Full article
