Abstract

En 中文

• Calcination controls phase change and crystallite growth in ZnAl-MMO. • In-situ growth of ZIF-8 forms defined oxide/MOF heterostructures. • Structural and optical properties are tuned through ZIF-8 loading. • Reduced PL intensity indicates improved interfacial charge separation. • The optimized MZ8-15% achieved 98.4% indigo carmine degradation efficiency.
