Nitrogen defects/boron dopants engineered tubular carbon nitride for efficient tetracycline hydrochloride photodegradation and hydrogen evolution

Template-free synthesis of Mn2+ doped hierarchical CuS yolk–shell microspheres for photocatalytic reduction of Cr(vi)

“…[25][26][27] And the simultaneous presence of inner and outer surfaces leads to a relatively large specific surface area, which is expected to increase the number of accessible active sites significantly, and ultimately enhance the surface reaction. [28][29][30] Many typical semiconductor materials, such as TiO 2 , 31 MoS 2 , 32 CuO, 33 WO 3 34 and C 3 N 4 , 35,36 have been reported to be applied in the photocatalytic field due to their special structure. Various synthetic routes have been employed to fabricate yolk-shell structures, including the hard-template method, soft-template method, and hydrothermal and solvothermal methods.…”

One-Dimensional P-Doped Graphitic Carbon Nitride Tube: Facile Synthesis, Effect of Doping Concentration, and Enhanced Mechanism for Photocatalytic Hydrogen Evolution

“…To further investigate the interaction of the P element with CNT, the high-resolution XPS tests were performed and the results are displayed in Figure 6 b–d. In the C 1s spectrum ( Figure 6 b) of the 0.9P-CNT sample, two significantly dominant peaks could be found at 284.8 and 288.2 eV, corresponding to the adventitious carbon and the sp 2 -hybridized carbon containing defects (-N=C-N), respectively [ 43 , 44 , 45 ]. The N 1s spectrum ( Figure 6 c) of the 0.9P-CNT sample can be subdivided into four smaller peaks with binding energies of 398.1, 399.4, 400.8, and 404.2 eV [ 46 , 47 ].…”

Constructing porous intramolecular donor–acceptor integrated carbon nitride doped with m-aminophenol for boosting photocatalytic degradation and hydrogen evolution activity

“…The photocatalytic performance of CN 30 is compared with those of other reported common photocatalyts in recent years (Table 2). 16,[56][57][58][59][60][61] Apparently, CN 30 shows a comparable photocatalytic performance, lower preparation cost and simpler preparation process. It is noteworthy that the CN 30 generated H 2 at atmospheric atmosphere and employed less amounts of catalyst to degrade high contents of pollutant.…”
