Recent advances in visible-light graphitic carbon nitride (g-C3N4) photocatalysts for chemical transformations

“…The design of g-C 3 N 4 -based materials includes zerodimensional quantum dots (QDs); 46,47 one-dimensional (1D) nanowires, 48,49 nanorods, [50][51][52] nanotubes, 53,54 and nanobelts; 55,56 two-dimensional (2D) nanosheets 57,58 and nanoplates; 59 and 3D microspheres, 60 micro-owers, 61 sandwich-like structures, 62 and porous structures. [63][64][65] For instance, combining theoretical calculation results with practical experimental ndings, the structure and electronic and optical properties of modied g-C 3 N 4 QDs were systematically and comprehensively explored by Bandyopadhyay et al 47 The preparation method is relatively simple for single-component 3D g-C 3 N 4 .…”

In situ controlled rapid growth of novel high activity TiB2/(TiB2–TiN) hierarchical/heterostructured nanocomposites

“…It was worth noting that the tapered nanorods present a rough surface with abundant exposed atoms ( Fig. 2 ), which was attributed to the different growth rates of the neighboring atom layers along the direction parallel to the crystal plane (pointed out by dash lines) [ 17 ]. It is possible that these exposed atoms could serve as high activity positions and might be used in future research in the fields of proton exchange membrane fuel cells, surface chemical modification and functionalization [ 18 – 19 ].…”

“…The different atom deposition rates of the neighboring atom layers along the direction parallel to the crystal plane results in nanorods with a rough surface with abundant exposed atoms ( Fig. 2 ) [ 17 ]. In consideration of the remarkably short time of the SHS processes, the Ti, N and B atoms would likely not have enough time to diffuse and rearrange.…”

Ce-Doped Graphitic Carbon Nitride Derived from Metal Organic Frameworks as a Visible Light-Responsive Photocatalyst for H2 Production

“…Morphology control is considered to be another effective way to increase the surface property and catalytic activity. There are some reports on the regulation of g-C 3 N 4 morphology, including nanorods [23,24], nanofibers [25], nanotubes [26], nanobelts [27], nanowires [28], and three-dimensional network [29].…”
