Efficient transformative HCHO capture by defective NH2-UiO-66(Zr) at room temperature

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.
