Reacting apparatus and method

The invention discloses a reacting apparatus and method. The method mainly comprises the following steps of containing a preset amount of supercritical fluid inside an enclosed body unit; and cooperatively arranging an electrode unit inside the body unit. The electrode unit comprises a positive electrode member used for bearing a material to be slaked (or a material to be processed), and a negative electrode member. The positive electrode member and the negative electrode member are respectively electrically connected to the anode and the cathode of a power supply unit. In this way, the surface impurities of the material to be processed can be dissolved through the supercritical fluid. After the positive electrode member and the negative electrode member are electrified in a cooperative way, impurity atom stripping is performed on the material to be slaked (or the material to the processed) with the positive electrode member as a sacrificial anode. By means of the positive electrode member and the negative electrode member, the slaking reaction time of the material to be slaked in a low-temperature condition can be shortened. The uniformity can be increased. Or the material to be processed can be optimized in low-temperature conditions. The structure is more compact and purified. Even chemical reactions or chemical deposition reactions can be performed in low-temperature conditions.
