“…Heterogeneous photocatalysis is an efficient degradation method of bio-persistent organics in aqueous media which are partially (if any) removed by conventional wastewater treatments (Friedmann et al, 2010, Basile et al, 2011, Ibhadon et al, 2013, Chong et al, 2010, Paramasivam et al, 2012, Gupta et al, 2015, Yola et al, 2014, Ali et al, 2011, Kansal et al, 2013, Kaur et al, 2015. The process relies on UVB-irradiation of a semiconductor metal oxide inducing formation of photo-excited electrons (e -) and holes (h + ) onto the catalyst surface.…”
