Special Issue Information

Dear Colleagues,

The continuous and ubiquitous use of fossil-based fuels as an energy source has raised serious concerns around the carbon emission and the associated climate change impact. Climate change as a result of greenhouse gas (GHG) emissions is one of the greatest challenges of the 21st century. This drives the need to develop and accelerate sustainable low-carbon technologies that will lead to scalable, clean, and environmentally benign alternative energy solutions, such as hydrogen, lower-emission fuel productions from sustainable or alternative feedstocks, biomass energy, large capacity renewable energy storage and conversion, etc. Carbon-neutral or negative and efficient energy production, storage, and utilization with sustainable processes that could reduce emissions are among the hot research areas both in academia and industry. Given this, Nanomaterials will dedicate a Special Issue on the latest research developments in innovative, scalable, and sustainable solutions for low-carbon emission energy production, storage and utilization, with the focus on ‘greening’ the processes, searching for alternative feedstocks, reducing environmental pollution, and enhancing renewable energy storage and conversion capability.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Strategically upcycling industrial wastes such as petroleum coke and dye wastewater into value-added materials through scalable and economic processes is an effective way to simultaneously tackle energy and environmental issues. Doping carbon electrodes with heteroatoms proves effective in significantly enhancing electrochemical performance through alterations in electrode wettability and electrical conductivity. This work reports the use of dye wastewater as the sole dopant source to synthesize N and S co-doped petroleum coke-based activated carbon (NS-AC) by the one-step pyrolysis method. More importantly, our wastewater and petroleum coke-derived activated carbon produced on a large scale (20 kg/batch) shows a specific surface area of 2582 m2 g−1 and an energy density of about 95 Wh kg−1 in a soft-packaged full cell with 1 M TEATFB/PC as the electrolyte. The scalable production method, together with the green and sustainable process, can be easily adopted and scaled by industry without the need for complex processes and/or units, which offers a convenient and green route to produce functionalized carbons from wastes at a low cost.
