Special Issue Information

Dear Colleagues

The conversion of sunlight into chemical energy—i.e. to drive thermodynamically uphill reactions such as the conversion of CO2 (also known as artificial photosynthesis) and the splitting of water to produce H2 by photocatalytic and photoelectrocatalytic reactions—can provide a package solution for the current negative impacts of global warming and growing energy demand using an inexhaustible energy source. Despite the longstanding interest in these processes and the extensive research efforts so far, challenges remain in improving the activity and selectivity for both reactions in energy applications and existing demonstrations are limited to small setups. 

In line with the increasing attention that photo-activated processes have received in the last year, the Special Issue "Photo- and photoelectro-chemical processes for energy applications", will report on the latest and most important fundamental and technological advances in water splitting and CO2 valorization, mainly focused on (but not limited to) two aspects: (i) Innovative photoactive materials, including improved synthesis and characterization methods, and (ii) efficient photoreactor geometries to enhance light harvesting and mass transfer. Authors are invited to submit their latest results; original papers, communications and reviews are welcomed.

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. Molecules 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 2700 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.

One of the most challenging issues in photocatalytic hydrogen evolution is to efficiently separate photocharge carriers. Although MoS2 loading could effectively improve the photoactivity of TiO2, a fundamental understanding of the charge transfer process between TiO2 and MoS2 is still lacking. Herein, TiO2 photocatalysts with different exposed facets were used to construct MoS2/TiO2 heterostructures. XPS, ESR, together with PL measurements evidenced the Type II electron transfer from MoS2 to {001}-TiO2. Differently, electron-rich characteristic of {101}-faceted TiO2 were beneficial for the direct Z-scheme recombination of electrons in TiO2 with holes in MoS2. This synergetic effect between facet engineering and oxygen vacancies resulted in more than one order of magnitude enhanced hydrogen evolution rate. This finding revealed the elevating mechanism of constructing high-performance MoS2/TiO2 heterojunction based on facet and defect engineering. Full article
