Abstract

The invention discloses a p-type delafossite structure CuScO 2 Crystal material and its preparation method and application, the method comprises: step 1, preparation of reaction precursor: with Cu 2+ Source reactants and Sc 3+ The source reactant is used as the raw material, deionized water is used as the reaction liquid, and the reducing agent and mineralizing agent are added and stirred until completely dissolved to prepare the reaction precursor; step 2, the reaction precursor is subjected to hydrothermal treatment at 210-240°C After reacting for 12 to 48 hours, the reaction product was centrifuged to obtain a precipitate, and the precipitate was dried to obtain the p-type delafossite structure CuScO 2 crystal material. The present invention utilizes the single reaction of hydrothermal method to prepare gram-level CuScO 2 Crystal material, no need to adjust the pH value of the precursor reactant; and the present invention explores CuScO for the first time 2 As a catalyst material in electrolytic water oxygen evolution, it shows good electrolytic water oxygen evolution activity and stability under alkaline conditions.

Description

technical field

[0001] The invention relates to the technical field of synthesis and preparation of nanomaterials, in particular to a p-type delafossite structure CuScO 2 Crystal material and its preparation method and use. Background technique

[0002] Transparent conducting oxide (Transparent conducting oxide, TCO) materials are widely used in flat panel displays, solar photovoltaic cells, transparent electrodes of touch screens, special function window coatings and other thin film optoelectronics due to their high electrical conductivity and good optical transparency. devices and other fields. However, the TCO materials widely researched and applied at present are basically n-type semiconductors, such as SnO 2 、In 2 o 3 and ZnO et al. If p-type transparent conductive materials with excellent performance can be prepared, active devices such as transparent p-n junctions and transparent FETs can be fabricated, and even transparent circuits can be realized. Therefore, t...
