Why nobel metal based homogeneous catalysts performe in significantly higher TONS thatn first row metals?
Best insight from top research papers
Noble metal-based homogeneous catalysts outperform first-row metals in turnover numbers (TONs) due to their ability to perform single-site electrocatalysis at lower overpotentials, leading to higher catalytic efficiencies . However, the use of rare metals like Ru and Ir in these catalysts poses scalability and cost limitations . In contrast, first-row transition metal catalysts face challenges in accommodating the oxidative equivalents required for water oxidation catalysis, resulting in limited success in achieving high TONs . Strategies involving metal-ligand cooperativity with first-row metals have shown promise in enhancing catalytic performance, but the development of efficient, robust, and scalable catalysts remains a challenge . The synergy between metals in bimetallic nanoparticles, like Au-Ru, can lead to higher catalytic efficiencies, potentially surpassing monometallic structures in certain reactions .

What is a difference between heterogenous and homogeneous single-atom catalysis?4 answersHeterogeneous single-atom catalysis refers to the dispersion of single atoms of a catalytically active element on a surface of a more inert and catalytically selective host metal. This allows for the creation of well-defined active sites with unique properties, such as high activities, selectivities, and stabilities. In contrast, homogeneous single-atom catalysis involves the use of single-atom catalysts (SACs) that behave in a similar fashion to homogeneous transition-metal catalysts. SACs are typically prepared through synthetic routes that result in a high load of metal atoms, allowing for full utilization of all metal atoms. The main difference between the two is the nature of the catalyst: heterogeneous single-atom catalysis involves the dispersion of single atoms on a surface, while homogeneous single-atom catalysis involves the use of SACs that behave like homogeneous catalysts.
