Ni-Cu synergy for efficient CO₂ conversion

This work highlights the power of Ni–Cu catalytic systems for CO₂ valorization via hydrogenation over graphitic carbon nitride (g-C₃N₄). By combining complementary functionalities—Cu favoring CO and methanol pathways, and Ni promoting methane formation—the study reveals how transition-metal synergy can be leveraged to steer product selectivity under mild conditions (1 bar).

The results provide new insight into how small Ni–Cu clusters are coordinated and stabilized within the g-C₃N₄ matrix, enabling precise control over activity, selectivity, and stability. This approach supports the rational design of low-cost, non-noble metal catalysts with reduced environmental impact. Importantly, preliminary toxicity studies confirm minimal cytotoxic effects at low concentrations, reinforcing the potential of these materials for sustainable catalytic applications.
