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 2θ (2-6°) 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 40^oC 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.
