hi everyone!!!

i  have research on ethanol conversion using catalyst Al2O3-TiO2 and Al2O3, but i have a problem on bond between Al2O3-TiO2, which Al that make bond with TiO2, can anyone describe it?? with everyone help here i can decide acidity and basic for catalyst so the reaction can react optimisely.

thank you everyone
