Method for Producing Mesoporous Transition Metal Carbide Layers with Defined Nanostructuring and Their Use in Electrocatalysis

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for producing mesoporous transition metal carbide layers with precise nanostructuring. The process involves initially forming a mesoporous metal oxide layer and then converting it into a mesoporous metal carbide by exposing it to a carbon-containing reducing atmosphere at temperatures above 650°C, with controlled heating rates. The resulting layers exhibit high porosity, regular pore structure, and excellent physical properties such as conductivity and mechanical stability, making them suitable for advanced material applications.
