Special Issue Information

Dear Colleagues,

Heterostructure nanomaterials have been explored as potential catalysts in many heterogeneous catalysis applications, such as photo/electrochemical water splitting, carbon dioxide conversion, pollutant remediation, hydrodesulfurization of petroleum, organic molecule transformations, etc. Herein, we invite authors to contribute original research articles or comprehensive review articles covering the most recent progress and new developments in the synthesis and utilization of heterostructure nanomaterials for highly efficient and novel processes associated with catalytic applications in energy, the environment, and sustainability. This Special Issue aims to cover a broad range of subjects from heterostructure nanomaterials synthesis to the design and technologies with nanomaterial integration. The article type includes full papers, communications, and reviews. Potential topics include but are not limited to:

  • Heterostructure nanomaterials development, synthesis, and fabrication for catalytic reactions;
  • Design and preparation of novel nanotextured/nanostructured surfaces for improved energy storage and conversion efficiencies;
  • Low-dimensional nanomaterials or nanocomposites for catalysis applications;
  • Green techniques for heterostructure nanomaterials processing;
  • Nanomaterial-based technologies for environmental and sustainable catalysis issues;
  • Other studies of nanoscience and nanotechnology associated with catalysis and sustainability.

Abstract
Copper-doped bismuth vanadate/graphitic carbon nitride (BiVO4/g-C3N4) nanocomposite materials were successfully fabricated using a sonochemical approach. Cu-doped BiVO4/g-C3N4 nanocomposite photocatalysts could improve electron/hole (e/h+) pair separation, stability, and light-harvesting [...] Read more.
Copper-doped bismuth vanadate/graphitic carbon nitride (BiVO4/g-C3N4) nanocomposite materials were successfully fabricated using a sonochemical approach. Cu-doped BiVO4/g-C3N4 nanocomposite photocatalysts could improve electron/hole (e/h+) pair separation, stability, and light-harvesting efficiency compared to pristine BiVO4 or g-C3N4, resulting in the enhancement of photocatalytic activity. The optimal parameters, such as pH value at 10, photocatalyst dosage of 0.4 g L−1, and 10 mol% Cu-doped BiVO4/g-C3N4 photocatalyst, were determined to degrade initial concentration of 20 ppm Bisphenol A, which could be completely removed after 90 min. Furthermore, the excessive doping of copper (> 10 mol%) could not synthesize the pure monoclinic scheelite phase, which substantially resulted in the reduction of the photocatalytic activity.

Using solar energy to remove antibiotics from aqueous environments via photocatalysis is highly desirable. In this work, a novel type-II heterojunction photocatalyst, MgSn(OH)6/SnO2, was successfully prepared via a facile one-pot in situ hydrothermal method at 220 °C for 24 h. The obtained heterojunctions were characterized via powder X-ray diffraction, Fourier-transform infrared spectroscopy, transmission electron microscopy, and ultraviolet-visible diffuse reflectance spectroscopy. The photocatalytic performance was evaluated for photodegradation of tetracycline solution under ultraviolet irradiation. The initial concentration of tetracycline solution was set to be 20 mg/L. The prepared heterojunctions exhibited superior photocatalytic activity compared with the parent MgSn(OH)6 and SnO2 compounds. Among them, the obtained MgSn(OH)6/SnO2 heterojunction with MgCl2·6H2O:SnCl4·5H2O = 4:5.2 (mmol) displayed the highest photocatalytic performance and the photodegradation efficiency conversion of 91% could be reached after 60 min under ultraviolet irradiation. The prepared heterojunction maintained its performance after four successive cycles of use. Active species trapping experiments demonstrated that holes were the dominant active species. Hydroxyl radicals and superoxide ions had minor effects on the photocatalytic oxidation of tetracycline. Photoelectrochemical measurements were used to investigate the photocatalytic mechanism. The enhancement of photocatalytic activity could be assigned to the formation of a type-II junction photocatalytic system, which was beneficial for efficient transfer and separation of photogenerated electrons and holes. This research provides an in situ growth strategy for the design of highly efficient photocatalysts for environmental restoration. Full article
