Abstract
A preparation method and application of a bismuth selenide / molybdenum selenide heterostructure electrode material, which relates to a preparation method of a bismuth selenide / molybdenum selenide heterostructure electrode material. The purpose of the invention is to solve the problems of poor cycle performance and rate performance of the existing sodium ion batteries. Method: 1. Synthesis of Bi 2 Se 3 ; Two, prepare Bi 2 Se 3 / MoSe 2 heterostructure to obtain bismuth selenide / molybdenum selenide heterostructure electrode material. The present invention tests the electrochemical performance of the prepared bismuth selenide / molybdenum selenide heterostructure electrode material, and the cyclic voltammetry and constant current charge and discharge experiments show that the electrode material has a good rate performance, at 0.1A g ‑1 Under the current density, about 360mAhg can be obtained ‑1 The mass-specific capacity has no obvious decay after 50 cycles. The invention can obtain a bismuth selenide / molybdenum selenide heterostructure electrode material.
Description
A kind of preparation method and application of bismuth selenide / molybdenum selenide heterostructure electrode material technical field The present invention relates to a kind of preparation method of bismuth selenide / molybdenum selenide heterostructure electrode material. Background technique With the increasingly serious impact of greenhouse gases on the environment, solving environmental problems is one of the most urgent problems to be solved at present. one. Energy from fossil fuels is considered to be one of the main sources of greenhouse gases. To reduce greenhouse gas emissions, it is necessary to expand Clean energy usage. However, due to the intermittent nature of clean energy, it is difficult to continuously supply energy to the power system. Therefore, increase the The proportion of clean energy in the total power supply must require energy storage or conversion devices as a relay to ensure the power supply. continuity. In addition, the exhaust emiss...
