WebJan 1, 2024 · BiVO4 can form in three crystal structures: monoclinic scheelite-type, tetragonal scheelite-type and tetragonal zircon-type [9]– [11]. The crystal structures strongly affect photocatalytic properties. Among these three structures, monoclinic scheelite phase is the most desirable because of its high photocatalytic activity [12]. WebDec 29, 2024 · Dissolution ratio curves showed that Ni2+, Zn2+, and Co2+ cations were incorporated into the mineral structure during magnetite crystal growth. The results indicate that the transformation of green rust to magnetite is accelerated by metal impurities, and that magnetite is a highly effective scavenger of trace metals during mineral …
