High-performance electrocatalytic microfiltration CuO/Carbon membrane by facile dynamic electrodeposition for small-sized organic pollutants removal

Recent Developments of Membrane Technology for Wastewater Treatment

“…The electrocatalytic performance of the membrane was improved by uniformly deposition of CuO electrocatalysts on a coalbased carbon membrane. The obtained membrane showed superior removal capability and it showed great potential, high permeability and removal efficiency for the removal of small-sized organic pollutants [42]. Sheikhi et al studied development of kaolinitic claybased ceramic membrane for investigation of inline coagulation-MF (IMF) process performance for oily wastewater.…”

Recent progress in nanomaterial-functionalized membranes for removal of pollutants

“…prepare electrocatalytic micro-filtration CuO/carbon membrane by a simple-step dynamic electrodeposition method to remove the organic pollutants such as rhodamine B, and its removal efficiency can reach 99.96%. The CuO/carbon membrane shows the higher permeability than carbon membrane ( Li et al., 2020a , and Li et al, 2020b ). Chang’s group developed an eco-friendly electrochemical approach using subsequent base and acid treatments to develop defect-rich porous aluminum substrates ( Periasamy et al., 2019 ).…”

“…The SiO 2 NPs (∼400 nm) decorated with AgNPs (∼30 nm) indicated broad-spectrum antibacterial activity against commonly found waterborne pathogens such as E. coli (92.7 ± 1.8%), P. aeruginosa (99.5 ± 0.3%), and S. aureus (73.3 ± 5.5%), thereby protecting the fouling of membrane without compromising rejection efficiency ( Figure 9 A (b)). In another report, tannic acid-stabilized TiO 2 NPs (∼150 nm) were employed for photoreduction of bacteria along with salt rejection ( Figure 9 B) ( Karthik et al., 2017 ; Li et al., 2020a , and Li et al, 2020b ). The strong interaction of nanomaterials with membrane is crucial for membrane stability and determines other physicochemical properties.…”

Self-driven in situ facile synthesis of CuO/Cu2O for enhanced catalytic reduction of 4-nitrophenol by acetic acid

“…CuO-based hybrid nanostructures such as CuO/Cu 2 O are very promising for the highly efficient catalytic conversion of 4-NP at low toxicity, and they are environmentally friendly. 15,16 CuO-based hybrid nanostructures prepared using various methods, such as chemical vapor deposition, 17 reactive sputtering, 18 electrodeposition, 19 hydrothermal methods 20 and so on, have been reported. For example, the preparation of the CuO/Cu 2 O catalyst via a hydrothermal method requires a strong alkali, and a high-temperature and high-pressure environment, which can increase the burden of sewage treatment as well as introducing safety risks.…”
