▎ 摘　　要

NOVELTY - Preparing strong coupling quantum dot heterojunction, which is in-plane interlayer quantum dot heterojunction based on electronic dynamic regulation, comprises, under the action of photocurrent, strong coupling upper layer which is molybdenum disulfide quantum dot layer structure, and lower layer which is nitrogen-doped reducing graphene oxide quantum dot layer structure. The molybdenum disulfide quantum dot layer comprises molybdenum disulfide of different phases (1T, 2H). USE - Method for preparing strong-coupling quantum dot heterojunction based on electronic dynamic regulation. Uses include but are not limited to electronic device, steam sensor, solar cell, catalytic and photoelectric detector. ADVANTAGE - The method has simple process, flexible and controllable, high performance, and high efficiency. The prepared quantum dot heterostructure is applied to the field of electro-catalysis hydrogen production, and the product performance is excellent. The method realizes laser induced heterogeneous material interface charge transfer so as to realize combined good composite material, at the same time, it can overcome the defect of low laser liquid phase ablation efficiency; and has maximum catalytic activity site, excellent conductivity, and realizes efficient catalytic hydrogen production. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of preparing strong-coupling quantum dot heterojunction based on electronic dynamic regulation.
