Shouli Bai,Ke Tian,Jonathan Chenhui Meng,Yingying Zhao,Jianhua Sun,Kewei Zhang,Yongjun Feng,Ruixian Luo,Dianqing Li,Aifan Chen +9 more
TL;DR: In this paper, a ternary photoanode of SnO2/BiVO4/rGO was fabricated by plain chemical vapor deposition (CVD) and metal-organic decomposition followed by spin-coated rGO.
Journal ArticleDOI
An α-Fe2O3/NiO p–n hierarchical heterojunction for the sensitive detection of triethylamine
Shouli Bai,Shouli Bai,Jingyi Han,Ning Han,Kewei Zhang,Jianhua Sun,Lixia Sun,Ruixian Luo,Dianqing Li,Aifan Chen +9 more
TL;DR: In this article, a novel p-n heterojunction of an α-Fe2O3/NiO composite was prepared by precipitation and hydrothermal methods and the structure, morphology and composition of the composite were characterized by numerous spectroscopic methods and its gas sensing properties for triethylamine (TEA) were also tested.
Journal ArticleDOI
rGO decorated NiO-BiVO4 heterojunction for detection of NO2 at low temperature
Shouli Bai,Shouli Bai,Kewei Zhang,Yingying Zhao,Qiangqiang Li,Ruixian Luo,Dianqing Li,Aifan Chen +7 more
TL;DR: In this article, a 3.7% rGO-NiO-BiVO4 composite was synthesized successfully by a simple hydrothermal and metal organic decomposition method.
Journal ArticleDOI
Synthesis of novel BiVO4/Cu2O heterojunctions for improving BiVO4 towards NO2 sensing properties.
Shouli Bai,Qiangqiang Li,Ning Han,Kewei Zhang,Pinggui Tang,Yongjun Feng,Ruixian Luo,Dianqing Li,Aifan Chen +8 more
TL;DR: The work demonstrates the as-synthesized BiVO4/Cu2O is a promising sensing material to detect NO2 gas and benefits from the novel p-n heterojunction between Bi VO4 and Cu2O, which forms a depletion layer at the interface, leading to resistance increase of composites in NO2.
Journal ArticleDOI
WO3-ZnFe2O4 heterojunction and rGO decoration synergistically improve the sensing performance of triethylamine
TL;DR: In this article, the effect of WO3/ZnFe2O4 ratio and rGO decorated amounts on the gas sensing of the composite was investigated, which is attributed to the synergistic effect of heterojunction interface modulation and RGO decoration.
