Special Issue Information
Dear Colleagues,
Photocatalysis is a cost-effective, environmentally friendly, and highly exciting approach that covers different fields such as chemical engineering and physical, chemical, and biological sciences. Photocatalytic nanomaterials are being studied widely for their outstanding features in hydrogen production via water-splitting procedures, methane (CH4) gas generation via the reduction in carbon dioxide (CO2), the purification of air, the inhibition of micro-organisms, the decontamination of water, and the degradation of diverse kinds of inorganic and organic pollutants including dyes, heavy metals, drugs, pesticides, etc.
Nanostructured materials are thought to be the ideal nano-photocatalysts because of their great stability, non-toxicity, low cost, and excellent photoactivity. Oxide semiconductors such as WO3, CeO2, SnO2, TiO2, SrTiO3, ZnO, Fe2O3, etc., are among the most efficient nano-photocatalysts. This is owing to their large bandgap and significant photocatalytic activities in the visible region. Other oxide and non-oxide (like CdS, ZnS, g-C3N4, etc.) nanomaterials also showed their efficiency as photocatalysts. The structural and morphological characteristics of photocatalysts could be fine-tuned to enhance their stability, their efficacy to produce electron–hole pairs upon absorbing light, and their photocatalytic efficiency. Furthermore, the production of novel photocatalytic nanocomposites and conductive polymers with nanostructures renders these products more easily recoverable and reusable for future runs.
Because of the fascinating prospects of nano-photocatalysts, creative researches of innovative and effective catalytic devices for environmental remediation and energy applications are increasingly sought.
The current Special Issue of “Nanomaterials” will cover the recent Progress in Photocatalytic Nanomaterials and Their Uses in Environmental Remediation and Energy Production, including the preparation of innovative and enhanced nano-photocatalysts using diverse techniques, the chemical and physical characterizations of nano-photocatalysts, their promising applications in the fields of energy production and environmental remediation, other related applications (such as biological activity, solar energy-driven nano-photocatalysis, etc.), the in-depth comprehension of the photocatalysis reaction mechanisms, theoretical investigations (numerical optimization, modeling, kinetics, and cost analysis of the processes), amongst others. This Special Issue welcomes the submission of original articles, review articles, and short communications that fit with all the above-mentioned points in the summary.

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.
