Fabrication of patterned calcium carbonate materials through template-assisted microbially induced calcium carbonate precipitation.

ABSTRACT: Patterned calcium carbonate materials with controlled morphologies have broad applications in both environmental and engineering fields. However, how to fabricate such materials through environmental-friendly methods under ambient conditions is still challenging. Here, we report a green approach for fabricating patterned calcium carbonate materials. This eco-friendly approach is based on template-assisted microbially induced calcium carbonate precipitation. As a proof of concept, by varying the templates and optimizing fabrication parameters, different patterned calcium carbonate materials were obtained. The optimized parameters include C _Ca²⁺ = 80 mM, T _i = 15 °C, and templates made of small-sized CaCO₃ particles with a concentrati
