“…It can be seen from the¯gure that both tested materials in this research have obvious symmetrical peaks, and the peak intensity of Au@CDs is higher than that of pure CDs, which indicates that the loading of Au on the CDs increases the defect sites of the photocatalyst, thus causing the increase of the EPR peak intensity. 53 This is consistent with the Raman results. Figure 7(d) is the EPR test result of 6-Au@CDs under dark and illumination for 1 h, it can be seen that the peak position of Au@CDs before and after illumination is consistent.…”

Synthesis and visible-light photocatalytic N2/H2O to ammonia at atmospheric pressure and room temperature is considered to be the most ideal ammonia synthesis technology. In this study, coal-based carbon dots (CDs) were prepared by H2O2 oxidation method using cheap and ubiquitous coal as the carbon source. Then the gold sol was connected to CDs to obtain a core-shell structure photocatalyst Au@CDs by sodium borohydride (NaBH4) reduction method. While characterizing the material structure, the photocatalytic N2/H2O to ammonia performance of Au@CDs was investigated. The results show that the introduction of CDs in Au @CDs photocatalysts can not only improve the performance of the catalyst to excite carriers in visible light, but also inhibit the recombination of photogenerated electron-hole pairs, promote the charge transport ability and make photogenerated electrons and holes move smoothly to the catalyst surface. Meanwhile, the adsorption and dissociation capacity of N2 on the catalyst surface can be improved, thereby the photocatalytic N2/H2O ammonia synthesis reaction of Au@CDs can proceed smoothly.

“…functions in nanoelectronics and optoelectronics. [7][8][9][10][11][12][13][14] 1D nanostructures could provide quick charge transfer along their axes, whereas 2D nanostructures (contain layered metal chalcogenides and MXenes) could confine electrons in their unique atomic layers. [15][16][17][18][19][20] The well-defined 1D geometry is beneficial for fast and longdistance electron transport as well as long-time photocatalytic stability, and their high length-to-diameter ratios and larger specific surface areas remarkably enhance the light absorption properties.…”

With the progress of dissimilar dimensional materials, 1D and 2D materials have been extensively investigated as heterogeneous photocatalysts, which realize the unique dimensionality‐dependent advantages and mitigate the disadvantages during the environmental and sustainable energy applications. The progress in 1D/2D heterogeneous photocatalysts stems from the combination of different growth modes between 1D and 2D nanostructures and the judicious control to establish the oriented 1D/2D interface. To promote this field, it is necessary to gain insights into the interface engineering in the 1D/2D heterogeneous photocatalysts. This mini‐review summarizes the designed synthesis and application of dimensional heterogeneous photocatalysts from 1D and 2D materials. Some typical research to overview the advantages of different types of interface engineered 1D/2D heterogeneous photocatalysts for various photocatalytic processes is highlighted in detail. At last, this review ends by drawing on more design strategies for such 1D/2D heterogeneous photocatalysts, which may inspire further developments of efficient dissimilar dimensional heterogeneous photocatalysts.

“…Moreover, ozone nanobubbles have also showed the more effectiveness than air-nanobubbles in the decomposition of pollutants [40][41][42]. So far, there is paucity of research reports on the application of nanobubbles in the advanced oxidation processes (AOPs) for pollution remediation [43,44]. Thus, synergistic effect of oxygen nanobubbles with AOPs and their detailed mechanisms is yet to be elucidated.…”

Nanobubbles have gained much attention due to their unusual properties such as large specific surface area, surface energy and internal energy, thereby, increase the surface reaction and improve the mass transfer efficiency. The long term stability of nanobubbles and generation of reactive oxygen species enables them to address various the development of nanobubbles technology, it is anticipated to realize totally chemicals free green technology. This study provides a novel nanobubble/AOPs technology, which will be more efficient and environmental friendly and will have broad application in waste water treatment and drinking water purification.
