The experimental results highlight the structural advantages of the curved defect site, revealing that high-curvature defective carbon (HCDC) demonstrates an adsorption capacity for acetylene that is almost two orders of magnitude higher than that of defective carbon.

In the DRM field, Ni-based catalysts attract wide attention due to their low cost and high activity. However, the carbon deposition over Ni-based catalysts always leads to rapid deactivation, which is still a main challenge.

The photothermal catalytic behavior of Ni<sub>3</sub>Zn@CeO<sub>2</sub> can maintain more than 70 h in DRM reaction.
