Special Issue Information

Dear Colleagues,

The light-induced conversion of carbon dioxide or its pH-neutral hydrated form, bicarbonate, in a selective manner, to C1 fuels and commodity chemicals (CH3OH, HCOOH, HCHO, etc.) contributes toward the group of negative emission technologies (NETs). Such global challenges underscore a second advantage, mainly economic, as this greenhouse gas is photochemically value-added as opposed to carbon sequestration. The nanocomposite design of photocatalysts offers the potential to greatly enhance catalytic turnovers from solar energy or other light sources by drawing on nature’s structures of flowers, foliage, leaves, and shells. This Special Issue is therefore named, “Nanocomposites for Photocatalytic CO2 and Bicarbonate Reduction”, with a call for submissions of research articles, communications, and reviews. Topics for consideration in this Special Issue include, but are not limited, to nanocomposites such as metal oxides, metal organic frameworks, semiconductors, organic dyes for energy transfer, electron transfer, and noble metals for plasmonics.

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.

Rising levels of atmospheric carbon dioxide due to the burning and depletion of fossil fuels is continuously raising environmental concerns about global warming and the future of our energy supply. Renewable energy, especially better utilization of solar energy, is a promising method for CO2 conversion and chemical storage. Research in the solar fuels area is focused on designing novel catalysts and developing new conversion pathways. In this review, we focus on the photocatalytic reduction of CO2 primarily in its neutral pH species of carbonate to formate. The first two-electron photoproduct of carbon dioxide, a case for formate (or formic acid) is made in this review based on its value as; an important chemical feedstock, a hydrogen storage material, an intermediate to methanol, a high-octane fuel and broad application in fuel cells. This review focuses specifically on the following photocatalysts: semiconductors, phthalocyanines as photosensitizers and membrane devices and metal-organic frameworks. Full article
