Remedying Defects in Carbon Nitride To Improve both Photooxidation and H₂ Generation Efficiencies

ACS Catalysis (2016)

Wenting Wu Jinqiang Zhang Weiyu Fan Zhongtao Li Lizhuo Wang

The outstanding visible light response of carbon nitride has aroused intense expectations regarding its photocatalysis, but it is impeded by the inevitable defects. Here, we report on a facile melamine-based defect-remedying strategy and resultant carbon nitride high-performance photocatalysts (R-C3N4). Melamine with amino groups and a triazine structure was selected as a "little patch" to passivate and remedy various defects inside carbon nitride. Such a remedying effect has been comprehensively proven by Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD) analyses, and the ninhydrin test. In addition, their effects on photocatalysis were also individually confirmed by chemical methods, including cyano reduction reactions and deamination reactions. Furthermore, melamine remediation can result in g-C3N4/mpg-C3N4 junctions, which also favors electron transfer and charge separation during the photocatalytic reaction. In order to explore its broader applications, R-C3N4 was used as a photocatalyst for the photooxidation reaction of 1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylate (1,4-DHP) and simultaneous H2 evolution. The conversion rates of 1,4-DHP and H2 production catalyzed by R-C3N4 were enhanced 2 and 6.5 times, respectively. This rational design is beneficial for the conversion of 1,4-DHP during the preparation of bioactive compounds and clean hydrogen production at the same time.

Palladium‐Catalyzed Distal C−H Selenylation of 2‐Aryl Acetamides with Diselenides and Selenyl Chlorides

Advanced Synthesis & Catalysis (2020)

Meicui He Linghui Gu Yuqiang Tan Yang Wang Yuchi Wang

Abstract A convenient and effective method of palladium‐catalyzed C−H selenylation of the 2‐aryl acetamides assisted with removable 8‐aminoquinoline with readily available diselenides and selenyl chlorides has been developed. This selenylation reaction is scalable and tolerates a wide range of functional groups, providing a straightforward way of the preparing unsymmetrical diaryl selenides and dibenzoselene‐pinone. Preliminary mechanistic studies indicated that a single‐electron transfer type mechanism and facile C−H metalation are operative. magnified image

Solar Cells: Ordered Single-Crystalline Anatase TiO₂ Nanorod Clusters Planted on Graphene for Fast Charge Transfer in Photoelectrochemical Solar Cells (Small 28/2017)

Small (2017)

Yang Wang Xueqin Liu Zhen Li Ya Cao Yinchang Li

Achieving efficient charge transport is a great challenge in nanostructured electrode-based photoelectrochemical cells. In article number 1700793, Zhen Li, Yanli Zhao, and co-workers, aligned single-crystalline anatase TiO2 nanorod clustergraphene architectures (rGO/ATRCs) are developed. The utilization of rGO/ATRCs in photoelectrochemical solar cells shows a 22% increase in photovoltaic efficiency over conventional nanoparticle–graphene hybrids, presenting a promising potential application in the photoelectrochemical energy field.

Assembling Graphene-Encapsulated Pd/TiO₂ Nanosphere with Hierarchical Architecture for High-Performance Visible-Light-Assisted Methanol Electro-Oxidation Material

Industrial & Engineering Chemistry Research (2019)

Bing Zhang Fan Yang Hongchen Liu Linan Yan Yang Wang

Photoactivated methanol oxidation electrocatalysis attracts broad interest in recent years. Herein, we report the novel reduced graphene oxide encapsulated with a Pd-modified TiO2 nanosphere (PTG) hierarchical composite by the electrostatic assembly strategy. The homodisperse tiny palladium nanoparticles (Pd NPs) on the TiO2 support (Pd/TiO2) ensure more active sites exposed, and graphene encapsulation ensures rapid electron transmission and high light utilization of the PTG material. This tailor-made composite exhibits not only high catalytic activity up to 1052 mA/mg but also good stability due to its distinct hierarchical structure and strong interaction between Pd/TiO2 core and graphene shell. Moreover, detailed characterizations showed that the properties of PTG are related to the particle size and crystal phase of the TiO2 support. The optimal PTG-400-650 (TiO2 support with mixed crystal and particle size of 400 nm) displays 2.0-fold enhancement in catalytic activity under light illumination, which is superior to previously reported TiO2-based photoelectrocatalysts.
