Abstract
In this work, excellent conductor element Ag was employed to bridge TiO2 nanotubes (TNTs) and PbO2 to construct an “expressway” for rapid electron transfer between the bases and active layers over the fabricated PbO2/SnO2-Sb/TNTs-Ag/Ti anode. Physicochemical characterizations reveal that elemental Ag can fill into the gaps between the TNTs, thus stabilizing structure and improving conductivity of the anode. Electrochemical and accelerated lifetime tests show the expanded reaction area (0.049–0.173 cm2), decreased charge transfer resistance (42.32–4.03 Ω cm−2), and prolonged lifetime (0.29–6.28 years). Furthermore, relatively higher average current efficiency (ACE) and less energy consumption (Esp) can be achieved during electrochemical oxidation of acid gold G (AY36) and rhodamine B (RhB) synthetic wastewaters, as well as shortening their degradation pathways. Our research looks forward to providing a novel Ag bridging design strategy for the synthesis of highly active and stable multilayer anodes.
期刊介绍:
The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
