Enhancement of Copper Catalyst Stability for Catalytic Ozonation in Water Treatment Using ALD Overcoating
Source abstract
Abstract
Atomic layer deposition (ALD) of alumina overcoating can significantly enhance the stability of copper oxide-based catalysts for catalytic ozonation of organic compounds in advanced water/wastewater treatment. The catalyst leaching was reduced by about 90% while high (up to 98%) activity was demonstrated in terms of total organic carbon (TOC) removal. Synchrotron X-ray absorption spectroscopy results indicated that the Al2O3 protecting layer passivated the under-coordinated copper sites, which were likely to be responsible for leaching.
