Abstract
Strontium substituted CoAl2O4 nanoparticles were prepared using a microwave combustion technique using L-alanine as a fuel. The following techniques were used to test the synthesized samples such as XRD, HR-SEM, EDX, DRS, FT-IR and VSM respectively.. Surface morphology showed nanosized crystalline grains agglomerated with flake-like and nano-sized pores are fused grain boundaries. The band gap was calculated using Kubelka-Munk (K-M) function and it is reduced from 3.32 to 3.18 eV. The Ft-IR bands ranging from 560 to 1100 cm-1 are caused by the cubic structure of Sr2+ doped CoAl2O4 nanoparticles(NPs). The bi-functional NPs CoAl2O4/SrO (x = 0.5) exhibited excellent catalytic performance and better conversion efficiency (conversion 98% and selectivity 95%) for glycerol
