“…(Hsueh et al, 1983), halides (Cl − and Br − ) (and Marković et al, 1999; Schmidt et al, 2001; Stamenkovic et al, 2001) and other impurities (P43-, NH4+, CO, SO 2 , H 2 S, etc.) (Macia et al, 2004; Stamenkovic et al, 2005; Halseid et al, 2008; He et al, 2010; Ong et al, 2013; Rahul et al, 2015; Briega-Martos et al, 2018). Therefore, strongly adsorbing anions/cations/impurities/ in situ generated adsorbed species on the catalyst surface interfere with the investigation of dissolution and reconstruction of nanoparticles, making it is hard to investigate the stability, origin of the loss of ESA, and catalytic activity of nanoparticles.…”
