摘 要：A versatile hydrothermal strategy for the growth of a centimeter-sized CaO/amorphous carbon rope was introduced in this article.It is demonstrated that the centimeter-sized rope is composed of abundant amorphous carbon "belt" and "stick" with small polygonal CaO particles in the size of 3.0-5.0 nm embedded in the "belt" and "stick" framework.With the increase in NaOH amount,polygonal Ca（OH）2 particles in the size of 0.5-3.0 μm are found,instead of the CaO/amorphous carbon rope.This morphology evolution results from the competition of structure-directing and hydrothermal-carbonizing of organic agents during hydrothermal reaction.These results may give good suggestions for the controllable growth of newly unique morphological micro/nano architectures in solution phase reactions.
