Researchers have developed a low-cost metal-free catalyst using edge-halogenated graphene nanoplatelets that shows remarkable electrocatalytic activity for oxygen reduction reaction, higher tolerance to methanol crossover/CO poisoning effects and longer-term stability than platinum-based catalysts.
A new high-throughput method identifies promising electrocatalysts for water oxidation, enabling the efficient storage of solar energy. The technique uses ultraviolet light and a fluorescent paint to test metal-oxide electrocatalysts, accelerating the discovery process.
Scientists at Brookhaven National Laboratory have developed a new electrocatalyst that efficiently generates hydrogen gas from water without using platinum. The novel nickel-molybdenum-nitride nanosheet catalyst outperforms traditional non-noble metal compounds and has the potential to unlock sustainable energy alternatives.
The new electrocatalysts have high activity, stability, and durability while containing only about one tenth the platinum of conventional catalysts used in fuel cells. This reduction leads to lower costs and environmental benefits by producing no harmful emissions.
Scientists have developed a new fuel-cell catalyst with a palladium core that protects precious platinum and enhances its reactivity. The new catalyst maintains high levels of activity even after 100,000 cycles of testing, compared to conventional catalysts that lose nearly 70% of their reactivity.
Researchers at Brookhaven National Laboratory stabilized platinum electrocatalysts using gold clusters, maintaining stability in accelerated tests. This breakthrough raises promising possibilities for synthesizing improved platinum-based catalysts.
