Abstract

A record-high HCHO capture capacity, reaching 49 mg g⁻¹, is achieved in about ten minutes, on defective NH₂-UiO-66(Zr) nano-octahedra. The adjacent bifunctional base/acid catalytic centers significantly facilitate the efficient HCHO adsorption and regenerative transformation of the adsorbed HCHO into less toxic formic acid and methanol.
