Facile regeneration of oxidized porous carbon nitride rods by the de-aromatization of the heptazine network in bulk g-C₃N₄

Abstract

The production of nanostructure g-C3N4 with remarkable charge separation efficiency in a one-step, green, and economic approach is of great challenge. Herein, one-dimensional oxidized porous carbon nitride rods are successfully...

Hydrogen production and degradation of organic pollutants catalyzed by C/Ti3C2/g-C3N4 hollow microsphere Schottky junctions with a built-in electric field in organic wastewater

“…10c), confirming the effective charge transfer caused by the excellent conductivity of Ti 3 C 2 . 63,64 In general, the conduction band potential ( E CB ) was observed to be 0.1 V more negative than the flat band potential. For CN-TCM-3, the E CB value was −1.73 V ( vs. NHE) which was more negative than that of g-C 3 N 4 (−1.43 V), and the valence band potential was calculated as 0.88 V ( vs. NHE) combined with the UV-vis DRS result (Fig.…”

Cyanamide-defect-induced built-in electric field in crystalline carbon nitride for enhanced visible to near-infrared light photocatalytic activity

“…Hydrogen evolution photocatalytic water splitting is believed to be a promising way to meet these demands. 1 To achieve a high hydrogen efficiency, several materials and/or structures have been reported, such as superior (in)organic semiconductors, 2 heterostructure constructions, [3][4][5] organic framework materials, 6,7 single-atom-site catalysts, 8,9 ionic 2D materials, 10 materials with micro-structural optimization, [11][12][13][14][15] etc. The reported systems have high efficiency in hydrogen generation from water, but most of them are high-cost, hazar-dous and/or highly operationally demanding; thus, there are still bottlenecks to their practical applications.…”

Unraveling Structural Carboxyl Defects in g‐C3N4 for Improved Photocatalytic H2 Evolution via Alternating Hydrogen‐Oxygen‐Plasma Treatment

“…Recently, the introduction of surface vacancies (C or N vacancies) and surface functional groups (–CN, –OH, −NH 2 or –COOH) have been verified to be useful in improving the selectivity and activity of photocatalytic reactions. [ 5–8 ]…”
