Zusammenfassung:•Different crystal phases of BiVO4 were synthesized by co-precipitation method.•In-situ high-temperature XRD was used to study the thermal stability and phase changes.•Presence of EDTA in synthesis yielded formation of iso-type homojunction.•The first tunable tetragonal BiVO4iso-type homojunction is reported. 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
