Coupling of Nd doping and oxygen-rich vacancy in CoMoO 4 @NiMoO 4 nanoflowers toward advanced supercapacitors and photocatalytic degradation

has a low band gap, which broadens the absorption range of the product and improves the utilization rate of visible light. The photocatalyst showed good degradation efficiency (all exceeding 96%) and cycling stability (96%) for all four dyes. This paper provides a new strategy and method for preparing doped polymetallic mixtures, which has potential application value.
