Graphite Oxide (multi-layer) composite with other materials has a huge application in various field of science, due to its excellent and unique properties. Even though from past decade, immense research has been done by materials scientists in this field, but the chemistry is still not yet satisfactory. Here, in this work, through the discovery of Nanogate structure, we have reported for the first time the experimental results that enlightened the clear chemistry between the GO and ZnS which is further supported by the DFT calculations. This novel synthesis method led to the discovery of nanogate structure sandwiched between the GO layers. The nanogate formation also shows enhanced properties for various applications like photocatalytic activities, etc. Due to the nanogate formation, there might be a possibility of enormous generation of electrons on excitation of the composite materials, which can be a boom for various applications like photocatalysis, water splitting, solar cell, etc.
氧化石墨（多层）与其他材料的复合材料因其优异独特的性能在科学的各个领域有着巨大的应用。尽管在过去十年里，材料科学家们在该领域进行了大量研究，但化学原理仍不尽人意。在此项工作中，通过发现纳米门结构，我们首次报道了阐明氧化石墨烯（GO）与硫化锌（ZnS）之间清晰化学原理的实验结果，密度泛函理论（DFT）计算进一步支持了这一结果。这种新颖的合成方法导致了夹在GO层之间的纳米门结构的发现。纳米门的形成还显示出在光催化活性等各种应用中的性能增强。由于纳米门的形成，复合材料在激发时可能会大量产生电子，这对于光催化、水分解、太阳能电池等各种应用来说可能是一大福音。
