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.

Provided are compositions that include at least one two-dimensional layer of an inorganic compound and at least one layer of an organic compound in the form of one or more polypeptides. Methods of making and using the materials are provided. The organic layer contains one or more polypeptides, each of which have alternating repeats of crystallite-forming subsequences and amorphous subsequences. The crystallite-forming subsequences form crystallites comprising stacks of one or more beta-sheets. The amorphous subsequences form a network of hydrogen bonds. A method includes i) combining one or more polypeptides with an inorganic material and an organic solvent, and ii) depositing one or more polypeptides, the inorganic material and the organic solvent onto a substrate. These steps can be repeated to provide a composite material that is a multilayer composite material. The composite materials can be used in a wide array of textile, electronic, semi-conducting, and other applications.
