AB  - Microplastic (MP) accumulation in the environment is accelerating rapidly, which 
      has led to their effects on both the ecosystem and human life garnering much 
      attention. This study is the first to examine the degradation of high-density 
      polyethylene (HDPE) MPs via photoelectrocatalysis (PEC) using a TiO(2)-modified 
      boron-doped diamond (BDD/TiO(2)) photoanode. This study was divided into three 
      stages: (i) preparation of the photoanode through electrophoretic deposition of 
      synthetic TiO(2) nanoparticles on a BDD electrode; (ii) characterization of the 
      modified photoanode using electrochemical, structural, and optical techniques; 
      and (iii) degradation of HDPE MPs by electrochemical oxidation and 
      photoelectrocatalysis on bare and modified BDD electrodes under dark and UV light 
      conditions. The results indicate that the PEC technique degraded 89.91 +/- 0.08% of 
      HDPE MPs in a 10-h reaction and was more efficient at a lower current density 
      (6.89 mA cm(-1)) with the BDD/TiO(2) photoanode compared to electrochemical 
      oxidation on bare BDD.
