Abstract:Selective removal of trace, highly toxic arsenic from water is vital to ensure an adequate and safe drinking water supply for over 230 million people around the globe affected by arsenic contamination. Here, we developed an Fe-based metal−organic framework (MOF) with a ferrocene (Fc) redox-active bridge (termed Fe-MIL-88B-Fc) for the highly selective removal of As(III) from water. At a cell voltage of 1.2 V, Fe-MIL-88B-Fc can selectively separate and oxidize As(III) into the less harmful As(V) state in the pre… Show more
“…Arsenic (As), a well-known toxic pollutant, poses a seriously harmful threat to human health and the environment. [1][2][3][4][5][6] Generally, it exists in the form of As(III) and As(V) in natural water. 7,8 Compared with As(V), As(III) is more harmful and dangerous due to its strong affinity towards thiols (the active sites of vital enzymes in biological organisms).…”
A new polyoxometalate-thiacalix[4]arene-based metal–organic photoelectrocatalyst is designed, and then applied to BiVO4 surface modification for enhanced photoelectrocatalytic oxidation of arsenic(iii) under simulated sunlight conditions.
