2Graphitic carbon nitride with different dimensionalities for energy and environmental applications显示文摘As a metal-free semiconductor,graphitic carbon nitride(g-C3N4)has received extensive attention due to its high stability,nontoxicity,facile and low-cost synthesis,appropriate band gap in the visible spectral range and wide availability of resources.The dimensions of g-C3N4 can influence the regime of the confinement of electrons,and consequently,g-C3N4 with various dimensionalities shows different properties,making them available for many stimulating applications.Although there are some reviews focusing on the synthesis strategy and applications of g-C3N4,there is still a lack of comprehensive review that systemically summarises the synthesis and application of different dimensions of g-C3N4,which can provide an important theoretical and practical basis for the development of g-C3N4 with different dimensionalities and maximises their potential in diverse applications.By reviewing the latest progress of g-C3N4 studies,we aim to summarise the preparation of g-C3N4 with different dimensionalities using various structural engineering strategies,discuss the fundamental bottlenecks of currently existing methods and their solution strategies,and explore their applications in energy and environmental applications.Furthermore,it also puts forward the views on the future research direction of these unique materials.Qiang Hao Guohua Jia Wei Wei Ajayan Vinu Yuan Wang Hamidreza Arandiyan Bing-Jie Ni 2020Nano Research2020,13,1:8
3Temperature dependent Raman and photoluminescence of vertical WS2/MoS2 monolayer heterostructures显示文摘Heterostructures from two-dimensional transition-metal dichalcogenides MX_2 have emerged as a hot topic in recent years due to their various fascinating properties. Here, we investigated the temperature dependent Raman and photoluminescence(PL) spectra in vertical stacked WS_2/MoS_2 monolayer heterostructures. Our result shows that both E_(2g)~1 and A_(1g) modes of WS_2 and MoS_2 vary linearly with temperature increasing from 300 to 642 K. The PL measurement also reveals strong temperature dependencies of the PL intensity and peak position. The activation energy of the thermal quenching of the PL emission has been found to be equal to 69.6 meV. The temperature dependence of the peak energy well follows the bandgap shrinkage of bulk semiconductor.Zhijian Hu Yanjun Bao Ziwei Li Yongji Gong Rui Feng Yingdong Xiao Xiaochun Wu Zhaohui Zhang Xing Zhu Pulickel M.
