Special Issue Information

Dear Colleagues, 

Hydrogen and energy have a long-shared history. The demand for hydrogen continues to increase as more and more industries are using hydrogen all over the world. The increasing cost of gasoline will soon make way for other competitive fuels and increase the potential of hydrogen in the mobility and transportation sector. Sustainable production of hydrogen is already the need of the hour. Hydrogen production methods can be classified as blue if the carbon produced in the process is captured. Similarly, they are classified as green when the primary energy source is carbon-free. Development is needed in both blue and green hydrogen production technologies. 

The aim of this journal is to monitor the advances in catalyst development for hydrogen generation for different technologies using renewable and nonrenewable sources. Efforts are needed for the development of catalysts to improve the efficiency of hydrogen production. This Special Issue will welcome papers on catalysts for steam methane reforming, partial oxidation, autothermal reforming of natural gas, gasification of coal, water electrolysis, photoelectrochemical method, electric arc deposition, ammonia cracking, methanol decomposition, formic acid decomposition, hybrid thermochemical cycles, hydrogen from liquid organic hydrogen carriers, etc. Although the aim will be to highlight non-precious-metal-based, scalable hydrogen generation catalysts that can be used in centralized as well as distributed hydrogen generation systems, we will also welcome studies on precious-group-metal catalysts. However, research on non-precious-metal catalysts will be preferred. Along with catalytic activity, its stability will be critical.

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. Hydrogen is an international peer-reviewed open access quarterly 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 1000 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.

Abstract
Molecular cobaloxime-based heterogeneous systems have attracted great interest during the last decades in light-driven hydrogen production. Here, we present a novel cobaloxime-tethered periodic mesoporous organosilica (PMO) hybrid (Im-EtPMO-Co) prepared through the immobilization of a molecular cobaloxime complex on the imidazole groups present in [...] Read more.
Molecular cobaloxime-based heterogeneous systems have attracted great interest during the last decades in light-driven hydrogen production. Here, we present a novel cobaloxime-tethered periodic mesoporous organosilica (PMO) hybrid (Im-EtPMO-Co) prepared through the immobilization of a molecular cobaloxime complex on the imidazole groups present in ethylene-bridged PMO. The successful assembly of a molecular cobaloxime catalyst via cobalt-imidazole axial ligation has been evidenced by several techniques, such as 13C NMR, Raman spectroscopy, ICP-MS, and XPS. The catalytic performance of Im-EtPMO-Co catalyst was essayed on the hydrogen evolution reaction (HER) under visible light in presence of a photosensitizer (Eosin Y) and an electron donor (TEOA). It showed an excellent hydrogen production of 95 mmol hydrogen at 2.5 h, which corresponded to a TON of 138. These results reflect an improved photocatalytic activity with respect to its homogenous counterpart [Co(dmgH)2(Im)Cl] as well as a previous cobaloxime-PMO system with pyridine axial ligation to the cobaloxime complex.
