Nanostructured ZnSe-graphene/TiO2 was synthesized by a hydrothermal-assisted approach. ZnSe-graphene/TiO2 exhibited favorable adsorption of rhodamine B, a wide wavelength absorption range, and efficient charge separation. Reactive oxygen species were generated by the oxidation of 1,5-diphenyl carbazide to 1,5-diphenyl carbazone. The sonocatalytic reaction mechanism was proposed. These findings potentially broaden the applications of sonocatalytic technologies.

, p. 661 - 665 (2001)
The selective synthesis of diaryl carbazone using K3Fe(CN)6 as oxidant under alkaline condition in solid state is reported for the first time. Eight diaryl carbazone have been synthesized in excellent yields, and this method only needs cheap reagents, and simple procedure under mild condition.
Rapid synthesis of diaryl carbazone by N-bromosuccinimide and pyridine as the oxidation system

, p. 423 - 428 (1999)
A new and rapid synthetic method of diaryl carbazone (ArN=NCONHNHAr) from aryl substituted carbazide is reported for the first time. Eight of the compounds were prepared by oxidation of aryl substituted carbazide using N- Bromosuccinimide and pyridine as the oxidation system in good yield under mild condition. This method only need simple instrument and short reaction time. A possible mechanism is suggested.
A facile preparation of graphene-based MxSy visible light driven photocatalyst and study of photochemically generating of oxygen species

The as-synthesized graphene-MxSy (Sb2S3, MnS2, SnS) composites via a facile hydrothermal method efficiently catalyzed the photodegradation of methylene orange (MO) with high concentration in aqueous solutions under visible light irradiation. The generation of reactive oxygen species were detected through the oxidation reaction from 1,5-diphenyl carbazide (DPCI) to 1,5-diphenyl carbazone (DPCO). Based on the high photocatalytic activity, the graphene-SnS composite can be expected to be a practical visible light photocatalyst.
