Facile Synthesis of Highly Efficient One-Dimensional Plasmonic Photocatalysts through Ag@Cu2O Core–Shell Heteronanowires

“…52 The SPR peak in the product collected at 24 h shifted to 386 nm due to the disappearance of In order to demonstrate the applicability of our simple method, core-shell It was reported that in the photodegradation of organic pollutants, reactive species such as ·O 2 -, h + and ·OH played as bridge role of photocatalysts under the light irradiation, [57][58][59][60] and they could vary with the different photocatalysts. 61,62 To investigate the photocatalytic mechanism and to understand the better performance of 1D Ag@Cu 2 O core-shell phtocatalysts, the effect of scavengers on the degradation of MO was examined to clarify the contribution of different reactive species during photocatalysis study. We used p-benzoquinone (PBQ) as ·O 2 -scavengers, [57][58][59][60][63][64][65] triethanolamine (TEOA) as h + scavengers, 61,62,65 and isopropanol (IPA) as ·OH scavengers.…”

Synthesis of novel Cu2O/BiOCl heterojunction nanocomposites and their enhanced photocatalytic activity under visible light

“…So far, the composite of Cu 2 O with other semiconductors or conductive materials has been the most common and effective means to solve this problem. The introduction of semiconductors can form a heterojunction structure with Cu 2 O, such as Cu 2 O/TiO 2 [5,[19][20][21], Cu 2 O/CeO 2 [22], ZnO/Cu 2 O [23] and Cu 2 O/BiVO 4 [24,25], improving separation efficiency of photogenerated charge carriers and enhancing the photocatalytic activity and stability of composite under visible light irradiation.…”

One dimensional hierarchical nanostructures composed of CdS nanosheets/nanoparticles and Ag nanowires with promoted photocatalytic performance

“…53,54 To investigate the photocatalytic mechanism and to understand the better performance of the 1D hierarchical structure composed of CdS nanosheets and Ag nanowires, the effect of the scavengers on the degradation of MO was examined to clarify the contribution of different reductive and oxidative species during the photocatalytic reactions. P-Benzoquinone (PBQ), triethanolamine (TEOA), and isopropanol (IPA) were used as scavengers for the 55 and • OH species, 56 respectively, which were added into the MO solution together with the 1D Ag@CdS hierarchical nanowires before irradiation.…”
