In general, for all applications, a highly porous material with high surface area and pore volume significantly increases the performance majorly because of the enhanced reaction kinetics and more active sites. In this context, a stable mesoporous TMP material (pore sizes between 2 -50 nm, IUPAC ), which is also amorphous could combine all advantages for the applicational use due to a high number of active metal sites, significantly enhanced mass transfer through the compound and a more negative Gibbs energy of formation compared to the crystalline analogue. Typically, mesoporosity is achieved via template-assisted synthesis routes. Despite the huge potential, template-based synthesis of TMPs is highly challenging and expensive limiting the currently available metal compositions and the (up)scalability . A major issue is the incomplete removal of template/surfactant through acid etching or high temperature calcination which could harm the target phosphate mesostructure and its purity. These hurdles have stimulated the development of new strategies for the synthesis of TMPs, with a focus on template-free methods .
