Carbon defective g-C3N4 thin-wall tubes for drastic improvement of photocatalytic H2 production

Revisiting the roles of dopants in g-C3N4nanostructures for piezo-photocatalytic production of H2O2: a case study of selenium and sulfur

“…48 From the data, GCN illustrates a powerful EPR signal compared to SeCN, illustrating that some loss of carbon atoms happened in the modied samples. 49,50 Based on the analysis, it would recommend that there were some carbon defects during the thermal polymerization process when introducing S or Se into the catalysts' structures, thus enhancing catalytic outcomes thanks to strengthening the piezo effects.…”

Remarkably improved photocatalytic selective oxidation of toluene to benzaldehyde with O2over metal-free delaminated g-C3N4nanosheets: synergistic effect of enhanced textural properties and charge carrier separation

“…4e), further suggesting that E-g-C 3 N 4 (3) has carbon vacancies in the sample, which is consistent with a reported article. 56 The high-resolution deconvoluted O 1s spectrum of g-C 3 N 4 shows two peaks with binding energies of 532.49 eV and 533.92 eV, corresponding to the surface oxygen of hydroxyl groups (O-H) and the (O-N) intermediates, which formed as the intermediates of urea thermal-polymerization (Fig. S5c †).…”

Kinetically and Thermodynamically Favorable Ni–Al Layered Double Hydroxide/Ni-Doped Zn0.5Cd0.5S S-Scheme Heterojunction Triggering Photocatalytic H2 Evolution

“…An appealing and sustainable approach for converting renewable solar energy into chemical energy that can be stored is called photocatalytic H 2 evolution (PHE). − Designing and constructing comparable photocatalysts are crucial steps in PHE. Very recently, layered double hydroxide (LDH) materials have emerged as promising photocatalysts for H 2 evolution. − Nevertheless, the low availability of photogenerated carriers of the single-phase LDH-based photocatalysts seriously limits their application. − To solve these issues, a multitude of strategies, including interfacial engineering, , defect control, , element doping, , morphology regulation, and construction of heterojunctions, , have been proposed to accelerate the separation and migration of carriers. It is widely known that kinetics and thermodynamics are greatly important for exploring the photocatalytic reaction, and the improvement in photocatalytic activity depends on not only kinetics but also the thermodynamic level .…”
