Abstract

We demonstrate a novel approach for synthesizing porosity-controlled calcium carbonate by one-step thermal decomposition of various calcium carboxylate derivatives as well as their mixtures with different molar ratios. By varying the volume content of calcium in the calcium compounds or mixtures, the resulting porous calcium carbonate exhibits distinct porosity and structures that are very promising for various applications.
