摘要

•Development of rational designed multi-component inorganic bulk heterostructure.•Versatile FeOOH nanografting of Al-based SrTiO3 as core–shell nanoflower-like heteronanostructure.•Enhanced solar light-driven photodegradation capability of Al:SrTiO3/Al2O3@Fe3O4/•FeOOH.•TEM reveals the presence of the lamellar FeOOH onto Al-based SrTiO3.•Availability of free charges and n-doping indicated by oxygen-deficient nature of interface.•The nanoflower-like morphology leads to effective photocatalytic performance.
