Suppressing Jahn-Teller distortion of MnO₂ via B-Ni dual single-atoms integration for methane catalytic combustion.

ABSTRACT: Precisely managing electron transfer pathways throughout the catalytic reaction is paramount for bolstering both the efficacy and endurance of catalysts, offering a pivotal solution to addressing concerns surrounding host structure destabilization and cycling life degradation. This paper describes the integration of B-Ni dual single-atoms within MnO₂ channels to serve as an electronic reservoir to direct the electron transfer route during methane catalytic combustion. Comprehensive analysis discovers that B atoms weaken the interaction between O and Mn atoms by forming bonds with lattice oxygen atoms. Meanwhile, Ni atoms facilitate electron transfer to achieve the heightened activity of MnO₂. The B-Ni dual-sites instead of Mn (IV) could accommodate excess electrons ge
