Introduction
Non-precious metal catalysts have gained significant attention in the field of
catalysis due to their cost-effectiveness and abundance. These catalysts offer a sustainable alternative to
precious metal catalysts, which are often expensive and scarce. This article addresses various important questions about non-precious metal catalysts, focusing on their types, applications, advantages, and challenges.
What are Non-Precious Metal Catalysts?
Non-precious metal catalysts are catalytic materials that do not include precious metals such as platinum, palladium, and rhodium. Instead, they are composed of more abundant and less expensive metals like
iron,
cobalt,
nickel, and
copper. These catalysts are used to facilitate various chemical reactions in industrial processes, energy production, and environmental applications.
