Synthesis and Characterisation of Nanoporous Folic Hemin Materials and Nanoporous Hemin Materials

Hemin like folic acid, FA, can replicate biological functions within inorganic materials. This study is aimed at fine-tuning the features of typical mesoporous silica derived using FA as a template referred to as nanoporous folic materials, NFM-1, by replacing FA progressively in the synthesis gels with equivalent moles of hemin to form nanoporous folic hemin materials, NFHM-1 (hemin, 3.12-50%), and nanoporous hemin materials, NHM-1. We found that increasing the ratio of hemin to FA decreases the intensity of the mesoscale peaks between 2 theta (2-6(degrees)) and the stacking array of petrin of the folate that is gradually replaced by that of hemin. The spectroscopic features and XRD patterns for samples synthesised at 40degree celsius were similar to those obtained at room temperature, RT. Various morphology such as spheres, twisted rods, hierarchical architectures, flower-like, and ribbons were observed for these samples.
