A solvothermal process was developed for the preparation of cauliflower-like Bi2S3 from N,N-dimethylformamide （DMF） solution of bismuth nitrate [Bi（NO3）3.5H2O] and thioacetamide （TAA） with 2-undecyl-1-dithioureido-ethyl-imidazoline （SUDEI） as the morphology-controlling agent. The obtained Bi2S3 products were characterized by transmission electron microscopy （TEM）, scanning electron microscopy （SEM）, and X-ray diffraction （XRD）, etc. The sensing properties of Bi2S3 with different morphologies were evaluated by the electrochemical analysis of dopamine （DA） and ascorbic acid （AA） coexisting solution. The results showed that cauliflower-like Bi2S3 showed a better resolving ability than rod-like Bi2S3 for the simultaneous determination of DA and AA,

Years of research have demonstrated that the use of multiple components is essential to the development of a commercial photoelectrode to address specific bottlenecks,such as low charge separation and injection efficiency,low carrier diffusion length and lifetime,and poor durability.A facile strategy for the synthesis of multilayered photoanodes from atomic-layer-deposited ultrathin films has enabled a new type of electrode architecture with a total multilayer thickness of 15–17 *** illustrate the advantages of this electrode architecture by using nanolayers to address different bottlenecks,thus producing a multilayer photoelectrode with improved interface kinetics and shorter electron transport path,as determined by interface *** photocurrent density was twice that of the bare structure and reached a maximum of 33.3±2.1 mA cm^(−2) at 1.23 *** integrated overall water-splitting cell consisting of an electrocatalytic NiS cathode and Bi_(2)S_(3)/NiS/NiFeO/TiO_(2) photoanode was used for precious-metal-free seawater splitting at a cell voltage of 1.23 V without *** results and root analyses suggest that the distinctive advantages of the electrode architecture,which are superior to those of bulk bottom-up core–shell and hierarchical architectures,originate from the high density of active sites and nanometer-scale layer thickness,which enhance the suitability for interface-oriented energy conversion processes.

Accelerated separation of photogenerated charge carriers and enhanced photocatalytic performance of g-C3N4 by Bi2S3 nanoparticles

引用

Chinese Journal of Catalysis 2020年第2期41卷 249-258页

作者： Qiang Hao Ci’an Xie Yongming Huang Daimei Chen Yiwen Liu Wei Wei Bing-Jie Ni Beijing Key Laboratory of Materials Utilization of Nonmetallic Minerals and Solid Wastes School of Materials Science and TechnologyChina University of Geosciences BeijingBeijing 100083China Centre for Technology in Water and Wastewater(CTWW) School of Civil and Environmental EngineeringUniversity of Technology Sydney(UTS)SydneyNSW 2007Australia

Employing photothermal conversion to improve the photocatalytic activity of g-C3N4 is rarely reported previously. Herein, different ratios of g-C3N4/Bi2S3 heterojunction materials are synthesized by a facile ultrasonic method. Advanced characterizations such as X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy are employed to analyze the morphology and structure of the prepared materials. Compared with sole counterparts, the heterojunction materials CN-Bi S-2 exhibit significantly enhanced photocatalytic performance, which is 2.05-fold as g-C3N4 and 4.42-fold as Bi2S3. A possible degradation pathway of methylene blue(MB) was proposed. Based on the photoproduced high-energy electrons and photothermal effect of Bi2S3, the transfer and separation of electron-hole pairs are greatly enhanced and more active species are produced. In addition, the relatively high utilization efficiency of solar energy has synergistic effect for the better photocatalytic performance.
