对石墨相氮化碳(g-C_(3)N_(4))的表面和层间结构进行同时优化,可以显著提高其光生载流子分离效率.然而,将具有特定优势的改性策略有效整合,从而构建由体相到表面的电荷传输通道仍存在巨大挑战.在此,我们提出了一种利用羧基和钾离子共修饰g-C_(3)N_(4)的新方法,用于引导其动态电荷转移过程.具体而言,我们将羧基官能团修饰在表面,通过其吸电子效应产生的驱动力改善表面的载流子动力学.同时,我们将钾离子插入g-C_(3)N_(4)层间,通过连接相邻层间促进载流子的跨层传输.该双功能光催化剂在无需助催化剂或牺牲剂的气固体系中实现了高达17.93μmol g^(-1)h^(-1)的CO产出速率,比未改性的g-C_(3)N_(4)高出8.68倍.这项工作有望进一步加深我们对光催化剂材料体相和层间区域载流子定向迁移机制的理解.

The H_(2)O_(2) -triggered prodrug activation represents a hot topic while the low H_(2)O_(2) level of cancer cells hindered the complete activation of parent drugs and resulted in the poor therapeutic effect. Here, we developed an H_(2)O_(2) amplifier fabricated by crosslinked lipoic acid nanocapsules(cLANCs), which would selectively elevate the intracellular H_(2)O_(2) level of cancer cells 3.4-fold higher than that of untreated cancer cells so as to speed up the activation of parent drug from the loaded prodrugs(Pro-5-FU). The cytotoxicity showed that the killing effect of Pro-5-FU loaded in cLANCs(Pro-5-FU@cLANCs) arrived up to 1.6-time higher than that of Pro-5-FU alone against A549 cells, and was even close to free 5-FU. The in vivo anticancer evaluation gave the tumor inhibition rate(TIR) and survival rate(SR) of Pro-5-FU@cLANCs against A549 tumor-bearing nude mice up to 73.1% and 80%,respectively, much higher than those of Pro-5-FU(TIR: 41.2%, SR: 20%) or free 5-FU(TIR: 50.6%, SR: 0%). This nanodrug constructed the first example that utilizes the drug carriers as H_(2)O_(2) amplifier to strengthen the prodrug activation.

Semiconductor photocatalytic technology has become one of the most important means to solve the current energy shortage and environmental pollution. Compared with the traditional photocatalysts, graphite carbon nitride has a wider range of light-harvesting and more stable physical and chemical properties. However, traditional thermally induced polymerization of nitrogen-containing precursors produces the melon-based carbon nitride solids with an amorphous or semi-crystalline structure, resulting in low conductivity and moderate photocatalytic activity. Recently, crystalline carbon nitride has attracted more and more attention in improving photocatalytic performance. Some significant progress regarding crystalline carbon nitride for the preparation of solar-fuel and environmental purification has also been *** review describes the recent advances in the design and synthesis of crystalline carbon nitride photocatalysts. A brief description of the unique physical and chemical properties of crystalline carbon nitride was given. Later, the synthetic and modification strategies are being introduced. Then, the photocatalytic application of crystalline carbon nitride was discussed, mainly including photocatalytic H2 production,photocatalytic CO2 reduction, and photocatalytic degradation of pollutants. Finally, the challenges and future directions of crystalline carbon nitride photocatalysts are briefly introduced.

Magnetite （Fe3O4） has been used for thousands of years as one of the important magnetic materials. The rapid developments of thin film technology in the past few decades attract the attention of material scientists on the fabrication of magnetite thin films. In this article, we present an overview of recent progress on Fe3O4 thin films. The widely used preparation methods are surveyed, and the effect of sub- strates is discussed. Specifically the modified Fe3O4 thin films exhibit excellent electrical and magnetic properties compared with the pure films. It is noteworthy that modified Fe3O4 thin films can be put into two categories：（1） doped films, where foreign metal ions substitute iron ions at A or B sites： and （2） hybrid films, where magnetite phases are mixed with other materials. Notably, Fe3O4 thin films show great potentials in many applications such as sensors and batteries. It is expected that the investigations of Fe3O4 thin films will give us some breakthroughs in materials science and technology.

TiO_2 nanotubes(TNTs) have drawn tremendous attention owing to their unique architectural and physical properties. Anodizing of titanium foil has proven to be the most efficient method to fabricate well-aligned TNTs,which, however, usually produces amorphous TNTs and needs further thermal annealing. Recently, a water-assisted crystallization strategy has been proposed and investigated by both science and engineering communities. This method is very efficient and energy saving, and it circumvents the drawbacks of thermal sintering approach. In this paper, we review the recent research progress in this kind of lowtemperature crystallization approach. Here, various synthetic methods are summarized, and the mechanisms of the amorphous–crystalline transformation are analyzed. The fundamental properties and applications of the low-temperature products are also discussed. Furthermore, it is proved that the water-assisted crystallization approach is not only applicable to TNTs but also to crystallizing other metal oxides.

In recent years, solar desalination and water evaporation/purification with various artificial architectures have drawn significant attention. Herein, we introduce a rational design structure for efficient solar water evaporation and purification, focusing on the balance between water transportation and thermal *** wood after a simple flame treatment on the surface was utilized as the solar absorber, with a high solar absorbance(~90 %), good hydrophilicity, and excellent heat localization abilities. Besides,a thermal insulator(polystyrene foam) was used to further reduce the thermal loss, and the optimized ratio between the water path and thermal insulator was obtained. A set of floating foam-flamed-wood(F-F-wood) devices were fabricated with a high evaporation rate of 3.92 kgm-2 h-1, exhibiting photothermal purification abilities from seawater and wastewater containing organic dyes and heavy metals. This study sheds light on the rational design of scalable and low-cost devices for solar water evaporation and purification.
