Synthesis of Mo-Pt/CeO Dual Single-Atom Nanozyme for Multifunctional Biochemical Detection Applications.

Elaborated structural modulation of Pt-based artificial nanozymes can efficiently improve their catalytic activity and expand their applications in clinical diagnosis and biochemical sensing. Herein, a highly efficient dual-site peroxidase mimic composed of highly dispersed Pt and Mo atoms is reported. The obtained Mo-Pt/CeO exhibits exceptional peroxidase-like catalytic activity, with a V as high as 34.

Incorporation of CeO with Ni-Co mixed metal phosphide boosts electrochemical seawater oxidation performance.

Electrochemical seawater oxidation has been regarded as one of the most promising strategies for cost-efficient production of hydrogen from the standpoint of sustainability, but suffers from a competitive chlorine evolution/oxidation reaction. Herein, we report a facile hard templated route to fabricate CeO incorporated Ni-Co mixed metal phosphide embedded in a carbon matrix (CeO-CoNiP@C). Benefiting from compositional and structural features, the obtained CeO-CoNiP@C possesses remarkably improved OER performance in 1 M KOH ( = 295 mV at 10 mA cm) compared with CoNiP@C.
