Estimating the term…
A group of reductive 2D materials (R2D) with extended reactive vacancies and a method for making the R2D with extended reactive vacancies are provided, especially the example of the reductive boron nitride (RBN). To create defects such as vacancies, boron nitride (BN) powders are milled at cryogenic temperatures. Vacancies are produced by milling, and the vacancies can be used to reduce various metal nanostructures on RBN. Due to the thermal stability of the RBN and the enhanced catalytic performance of metal nanostructures, RBN-metals can be used for different catalysts, including electrochemical catalysts and high temperature catalysts.
A reductive boron nitride (RBN), wherein the RBN is a defective hexagonal boron nitride with chemical reactive sites that are randomly distributed on its surface, wherein the chemical reactive sites are configured for reducing metal compounds or single metal atoms to their lower oxidation states, and wherein the chemical reactive sites are formed by mechanical grinding at a cryogenic temperature.
A method for making a reductive boron nitride (RBN) with extended reactive vacancies comprising mechanical grinding of hexagonal boron nitride at a cryogenic temperature to create extended reactive vacancies.
A method for making metal nanostructure decorated reductive boron nitride (RBN) comprising in liquid suspension:
