Emerging techniques for emerging contaminants (ECs): photo- and electro-chemical oxidation/reduction processes.

Emerging contaminants (per- and poly-fluoroalkyl substances, pesticides, pharmaceuticals, hormones, endocrine disruptors, etc.) have gained enormous research thrusts and public attention, due to their toxicity and resistance to conventional water treatment processes. A rapidly increasing body of research is being devoted to searching for advanced techniques for the removal of emerging contaminants. Among all the emerging techniques, photo- and electro-chemical oxidation/reduction processes are appealing because they are capable of producing strong oxidants (·OH, h⁺, SO₄·^-, ClO^-, etc.) and reductants (e^-_aq) by the use of clean energy (solar light and PV panel). The ease of automation and modular design endow photo-electrocatalytic techniques with the versatility and adaptability in on-site remediation projects and disaster-relief missions. Challenges and opportunities coexist in the journey to narrow the gap between academic advocation and industrial application. The purpose of organizing this special issue is to provide a fast lane of publication to promote the visibility of cutting-edge research in this area. Fundamental studies that can help us gain more mechanistic insights into material (photocatalyst and electrocatalyst) design and product transformation are of particular interest. Manuscripts focusing on pilot-scale studies and field tests are also welcome.
