Abstract
A convection-free flow reactor, including: a reactor body, including: a reaction chamber for housing a fluid; an inlet in fluid communication with the reaction chamber to allow input of a reactant fluid; an outlet in fluid communication with the reaction chamber to allow output of a product fluid; and an energy beam source device for providing an energy beam that irradiates the reactant fluid in the reaction chamber. The invention further provides a convection-free flow-type synthesis method.
