Phosphorus is one of the major essential nutrients for fruit growth and cannot be easily replaced. Its continually increasing demand represents a great challenge for the sustainable development of agriculture and our society. Currently phosphorus production relies only on nonrenewable phosphate rocks, so our research aims to recover the phosphorus from organic compounds by catalytic dephosphorylation in aqueous solutions. By hydrolysis of the phosphate ester bond, free phosphate anions will be released from biomass and agriculture wastes, which can then be separated by ion exchange methods. These inorganic phosphates can be utilized in phosphate fertilizer production. Our catalysts were synthesized with shape control to better study the active sites of them. And the dephosphorylation reaction was studied at various temperatures to evaluate the shape effect on rate constant, activation energy, and recyclability.
