Bismuth nitrate pentahydrate (Bi(NO3)3·5H2O, 98%) and ammonium vanadate (NH4VO3, 99.0%) were purchased from Afla Aeser and used without further purification. Silver nitrate (AgNO3), ferric chloride (FeCl3) and ammonium oxalate ((NH4)2C2O4) were obtained from Sinopharm Chemical Reagent (Shanghai, China) and used as received. All aqueous solutions were prepared with ultrapure water (>18.2 MΩ cm) from a tropism Milli-Q Plus system (Millipore). All glassware used in the following procedures were cleaned in a bath of freshly prepared 3:1 HCl:HNO3 (aqua regia) and rinsed thoroughly by ultrapure-water prior to use.
