Nevertheless, the interplay of several factors in deciding photocatalytic activity makes its rate elusive to many degrees. However, rather than emphasizing the role of shape anisotropy and the electronic parameters, this study attempts to highlight the role of the collective effects of the Given the small differences in size (14-45nm) and forms of the (Fe2O3) catalyst, we try to understand this variation of rate constant (k) using interface structure derived from electrochemical parameters.
