Special Issue Information

Dear Colleagues,

More than one-third of the human population are facing limited access to sanitary and safe drinking water. The effective removal of chemical contaminants, including oils/organic solvents, heavy metal ions, and dyes, from water is one of the major challenges we are facing in our efforts to mitigate this. Strategies to develop effective, economical, and robust methods for water purification are still urgently needed. To address such challenges in developing materials for water treatment or degradation of pollutants, this Special Issue aims to discuss state-of- the-art advances in the development of various photoactive molecule/polymer materials with good adsorption capacity, photodegradation ability of pollutants, and so on. Thus, we would like to invite authors to submit their original and high-quality research on theoretical calculation of photoactive molecules/polymers, novel photodegradable molecule/polymer design/synthesis, advanced characterization technologies, development of next-generation reusable and portable water purification appliances, development of water purification appliance products, and strategies toward high-performance photodegradable polymer materials.

Topics to be covered in this Special Issue include:

(1) Emerging novel photodegradable molecule/polymer design/synthesis;
(2) Emerging novel photoactive molecule/polymer design/synthesis for effective removal of water pollutes;
(3) Emerging development of next-generation reusable and portable water purification appliances.

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. Sustainability 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 2400 CHF (Swiss Francs).

Graphene quantum dots (GQDs) have been successfully used as a highly sensitive probe for the sensing of formaldehyde (HCHO) in an aqueous solution. Through static quenching, the probe utilizes the interaction between HCHO and GQDs to trigger the “turn off” fluorescence response, and has good selectivity. The probe can detect HCHO in a pure aqueous solution, and it also can still detect HCHO in a complex environment with a pH range from 4 to 10. The concentration of HCHO and the fluorescence intensity of GQDs show a good linear relationship within the range of HCHO of 0–1 μg/mL, which was much more sensitive than previous reports. The limit of HCHO detection by GQDs is about 0.0515 μg/mL. In addition, we successfully applied it to the actual food inspection. It is proved to be a selective, sensitive and visualized method to check whether the concentration of HCHO in the foods exceeds the regulatory limit, which presents a potential application in food safety testing.
