Remarkably enhanced catalytic performance in CoO_x/Bi₄Ti₃O₁₂ heterostructures for methyl orange degradation via piezocatalysis and piezo-photocatalysis.

ABSTRACT: A novel heterojunction composite of CoO_x/Bi₄Ti₃O₁₂ was synthesized through a combination of molten salt and photodeposition methods. The optimal sample exhibited superior performance in the piezocatalytic degradation of methyl orange (MO) dye with a degradation rate of 1.09 h^-1, which was 2.4 times higher than that of pristine Bi₄Ti₃O₁₂. Various characterizations were conducted to reveal the fundamental nature accountable for the outstanding piezocatalytic performance of CoO_x/Bi₄Ti₃O₁₂. The investigation of the band structure indicated that the CoO_x/Bi₄Ti₃O₁₂ composite formed a type-I p-n heterojunction structure, wi
