Facile one-pot synthesis of CuO–Bi2O3/MgAl2O4 catalyst and its performance in the ethynylation of formaldehyde [PDF]
HeliyonThe CuO–Bi2O3/MgAl2O4 catalyst was synthesized via one-pot synthesis and used to catalyze formaldehyde (HCHO) ethynylation. Coprecipitation using Cu2+, Bi3+, Mg2+, and Al3+ nitrates and NaOH generated Cu and Bi oxides and spinel MgAl2O4 phase.
