Implementing vanadium peroxides as direct air carbon capture materials.

ABSTRACT: Direct air capture (DAC) removal of anthropogenic CO₂ from the atmosphere is imperative to slow the catastrophic effects of global climate change. Numerous materials are being investigated, including various alkaline inorganic metal oxides that form carbonates via DAC. Here we explore metastable early d⁰ transition metal peroxide molecules that undergo stabilization via multiple routes, including DAC. Specifically here, we describe via experiment and computation the mechanistic conversion of A₃V(O₂)₄ (tetraperoxovanadate, A = K, Rb, Cs) to first a monocarbonate VO(O₂)₂(CO₃)^3-, and ultimately HKCO₃ plus KVO₄.
