AB  - A photoelectrochemical sensing platform based on ligand-variable metal clusters 
      charge transfer was established for the quantitative assay of ronidazole (RNZ) 
      using Ce-porphyrin-metal-organic frameworks/silver nanowires (Ce-Por-MOFs/AgNWs). 
      Rod-like Ce-Por-MOFs and well-dispersed sub-50 nm AgNWs were prepared using a 
      hydrothermal method and polyol strategy, and then through simple drop coating to 
      yield Ce-Por-MOFs/AgNWs nanocomposites. We investigated the intrinsic 
      semiconducting properties of the composites. More importantly, it was found that 
      the variable-valence metal node can provide electronic defect states similar to 
      those caused by multi-metal doping, synergizing with the surface plasmon effect 
      of AgNWs, which significantly improved the photoelectric conversion efficiency, 
      thereby resulting in excellent optoelectronic properties. In combination with 
      molecular imprinting, a competitive type trace photoelectrochemical sensor for 
      RNZ was constructed using Fe(2+) as the electron donor and probe. Under optimal 
      conditions, the sensor response is proportional to the logarithm of RNZ 
      concentration in the range 0.1-104 nM with a detected limit of 0.038 nM. The 
      recoveries ranged from 87.2 to 116% with relative standard deviations 
      (RSDs) < 6.5% (n = 3) in milk sample. This work reveals the charge-transfer 
      process of variable-valence metal nodes in MOFs during photoelectrochemical 
      processes, which will provide new insights for the sensing application of 
      variable-valence metal MOFs.
