With their single units sized between 1 to 100 nm, the nanomaterials have been constructed from these very tiny “blocks”, resulting in various morphologies with different chemical compositions and atoms arrangements. Especially for the two-dimensional (2D) ones, possessing only a few atoms thickness but much large lateral area, they show unconventional structure-related properties in physical, chemical, electronic as well as optical aspects comparing to their 3D counterparts. Till today, more and more researches have been carried out on the 2D nanomaterials electronic applications, they not only contribute to the size reduction/ performance optimization of the computer components in accord with the Moore's Law, but also provide new opportunities for the quantum computer development based on the spintronics studies. In the catalysis domain, the super high surface atoms ratio of 2D nanomaterials makes them exhibit tremendous advantages, which may benefit the cost reduction comparing with the traditional catalysts like noble metals. What’s more, achieving high energy/power densities may also be accomplished by using the 2D nanomaterials, showing their great application potentials in the new energy field. In a word, our group is very interested in these basic researches, and willing to manipulate the materials properties on their atomic scale. Exploring practical applications & Solving practical problems, we are born ready to make the world different!
