In-situ high temperature XRD study on thermally induced phase changes of BiVO4: The formation of an iso-type heterojunction

Abstract Different crystal phases of BiVO4 were synthetized by co-precipitation method with ethylenediaminetetraacetic acid (EDTA). In-situ high-temperature XRD was used to study the thermal stability and (ir)reversibility of phase changes. The presence of EDTA yielded a tunable iso-type homojunction BiVO4 within 360
