A novel in situ impregnation conversion method was proposed for constructing hierarchical porous metal-orgainc framework (MOF) films. This approach relies on the conversion of a Cu(OH)2@PVA precursor film into a Cu-MOF film via a controlled in situ growth process. The resulting MOF films exhibited high accessibility to active sites and robust free-standing properties.
Zhai et al. (Fri,) studied this question.
