A ground fault circuit interrupter (GFCI) device includes a ground fault detection module for detecting a ground fault in a neutral line of a plurality of current carrying lines and generating a ground fault signal in response thereto, including a neutral line detection coil having a magnetic core made of a silicon steel and through which the current carrying lines pass; a leakage current detection module for detecting the ground fault signal and detecting a leakage current signal on the current carrying lines, and generating a zero sequence current fault signal in response to either signal; and a drive module for receiving the zero sequence current fault signal and driving a switch module to disconnect the electrical connection of the current carrying lines in response thereto. The GFCI device can avoid false tripping when high frequency currents flow through the current carrying lines, improving user experience and enhancing safety.

The invention provides a two-dimensional chalcogenide, which is a crystalline material, and has a chemical formula of (NH)[SnS]·(CHN), cell parameters of a=b=13.2307(10) Å, c=19.335(2) Å, α=β=90°, and γ=120°, and space group of P6/mmc. The invention further provides a method for preparing the two-dimensional chalcogenide and use thereof in the adsorption of iodine vapor. The two-dimensional chalcogenide of the present invention is capable of removing iodine vapor of various concentrations (as low as 400 ppm) over a wide range of temperatures (25° C.-75° C.), without desorption of iodine after standing for a long time.
