Design of BDD-TiO2 Hybrid Electrode with P−N Function for Photoelectrocatalytic Degradation of Organic Contaminants

摘要: P−N hybrid electrode of boron-doped diamond (BDD) and TiO2 were designed fabricated via selective deposition onto BDD electrode. This exhibit high photoelectrocatalytic activities toward degradation acid orange II (AOII) 2,4-dichlorophenol (2, 4-DCP) due to the effect electrocatalytic photocatalytic particles. The structures confirmed by Raman spectra analysis. Atom force microscopy scanning electron showed that deposits consist adherent nanomicro-sized particles, scattered on substrate. AOII 2,4-DCP in a solution can be efficiently degraded at photoelectrocatalysis (PEC) process. Effect applied bias potentials pH values investigated. In electro-oxidation process, some intermediates such as phenols detected they accumulated with reaction evolution based a...
