Biocoordination Polymer Cross-Linking Structure to a 3D Star Topology Inorganic Photocatalyst Nanocrystal with Improved Hydrogen Evolution Performance.

An inorganic photocatalyst with a novel 3D star topology (ST) framework was obtained via multiple cross-linking of biocoordination polymers in one-step solvothermal conditions. It possessesd a large surface area (149.36 m2·g-1), among the highest value of the current reports, and represented the quantum size effect because of its 3D ST structure. The amino acid l-cysteine was introduced into the synthesis system to lead generation of the biometic coordination polymer through the amino acid dehydrate condensation and multiple cross-linking.
