The synthesis of one-dimensional (1D) semiconductor nanostructures has been studied intensively for a wide range of materials due to their unique structural and physical properties and promising potential for future technological applications. Among various strategies for synthesizing 1D semiconductor nanostructures, solution-phase synthetic routes are advantageous in terms of cost, throughput, modulation of composition, and the potential for large-scale and environmentally benign production. This article gives a concise review on the recent developments in the solution-phase synthesis of ID semiconductor nanostructures of different compositions, sizes, shapes, and architectures. We first introduce several typical solution-phase synthetic routes based on controlled precipitation from homogeneous solutions, including hydrothermal/solvothermal process, solution-liquid-solid (SLS) process, high-temperature organic-solution process, and low-temperature aqueous-solution process. Subsequently, we discuss two solution-phase synthetic strategies involving solid tem- plates or substrates, such as the chemical transformation of 1D sacrificial templates and the oriented growth of 1D nanostructure arrays on solid substrates. Finally, prospects of the solution-phase approaches to 1D semiconductor nanostructures will be briefly discussed. 展开更多

This paper reviews the solution-phase synthesis of nanoparticles via some routes at low temperatures, such as room temperature route, wave-assisted synthesis (γ-irradiation route and sonochemical route), directly heating at low temperatures, and hydrothermal/solvothermal methods. A number of strategies were developed to control the shape, the size, as well as the dispersion of nanostructures. Using diethylamine or n-butylamine as solvent, semiconductor nanorods were yielded. By the hydrothermal treatment of amorphous colloids, Bi2S3 nanorods and Se nanowires were obtained. CdS nanowires were prepared in the presence of polyacrylamide. ZnS nanowires were obtained using liquid crystal. The polymer poly (vinyl acetate) tubule acted as both nanoreactor and template for the CdSe nanowire growth. Assisted by the surfactant of sodium dodecyl benzenesulfonate (SDBS), nickel nanobelts were synthesized. In addition, Ag nanowires, Te nanotubes and ZnO nanorod arrays could be prepared without adding any additives or templates. 展开更多

Due to easy re-stacking,low yield of few-layered MXenes(f-MXenes),the applications of MXenes are mainly restricted in multi-layered MXenes(m-MXenes)state.Although f-MXenes can be prepared from m-MXenes,after exfoliation process,a mass of sediments which are still essentially compact MXenes are usually directly discarded,leading to low utilization of raw m-MXenes.Herein,a classified preparation strategy is adopted to exploit the raw m-MXenes and traditional MXenes sediments,taking multi-layered Ti_(3)C_(2)T_(x)MXene as an example.Via rational delamination and subsequent treatment to Ti_(3)C_(2)T_(x)sediments,we succeed in achieving classified and large-scale preparation of various Ti_(3)C_(2)T_(x)MXene derivatives,including few-layered Ti_(3)C_(2)T_(x)(f-Ti_(3)C_(2)T_(x))powders,f-Ti_(3)C_(2)T_(x)films,and Ti_(3)C_(2)T_(x)MXene-derived nanowires with heterostructure of potassium titanate and Ti_(3)C_(2)T_(x).We demonstrate the necessity of“step-by-step delamination”towards traditional Ti_(3)C_(2)T_(x)sediments to improve the yield of f-Ti_(3)C_(2)T_(x)from 15%to 72%;the feasibility of“solution-phase flocculation(SPF)”to fundamentally solve the re-stacking phenomenon,and oxidation degradation issues of f-Ti_(3)C_(2)T_(x)during storage;as well as the convenience of SPF to deal with time-consuming issues of fabricating Ti_(3)C_(2)T_(x)films.What’s more,alkali-heat treatment of final Ti_(3)C_(2)T_(x)sediments turns waste into treasure of Ti_(3)C_(2)T_(x)-derived nanowires,leading to 100%utilization of raw Ti_(3)C_(2)T_(x).The content of one-dimensional(1D)nanowires in the hybrids can be adjusted by controlling alkalization time.The 3D architecture heterostructure composed of 1D nanowires and 2D nanosheets exhibits gorgeous application potential.This work can expand preparation and application of various MXenes derivatives,promoting process of various MXenes. 展开更多

In this artide, highly [010]-oriented self-assembled LiCoPO4/C nanoflakes were prepared through simple and facile solution-phase strategies at low temperature and ambient pressure. The formation of 5-hydroxylmethylfurfural and levoglucosan via the dehydration of glucose during the reaction played a key role in mediating the morphology and structure of the resulting products. LiCoPO4 highly oriented along the (010)-facets exposed Li^+ ion transport channels, facilitating ultrafast lithium ion transportation. In turn, the unique assembled mesoporous structure and the flake-like morphology of the prepared products benefit lithium ion batteries constructed using two-dimensional (2D) LiCoPO4/C nanoflakes self- assembles as cathodes and commercial Li4Ti5O12 as anodes. The tested batteries provide high capacities of 154.6 mA·h·g^-1 at 0.1 C (based on the LiCoPO4 weight of 1 C = 167 mA·h·g^-1) and stable cycling with 93.1% capacity retention after 100 cycles, which is outstanding compared to other recently developed LiCoPO4 cathodes. 展开更多

A method using N,O-bis(trimethylsilyl)acetamide/N-hydroxysuccinimide ester(BSA/NHS) as coupling agents for dipeptide synthesis is descried. The coupling reaction between N-hydroxysuccinimide(NHS)esters and amines could be performed under mild conditions with N,O-bis(trimethylsilyl)acetamide(BSA) as coupling reagent and no additional acid/base is required. All byproducts and excessive reactants are water soluble or hydrolysable and easy to eliminate through water-washing at the purification stage.Moreover, all the reactants are inexpensive and widely used in conventional drug production. 展开更多

Main observation and conclusion We describe a practical and general protocol for immobilization of heterogeneous catalysts to mechanically robust porous ultra-high molecular weight polyethylene tablets using inter-facial Lifshitz-van der Waals Interactions.Diverse types of powderous catalysts,including Cu,Pd/C,Pd/Al2O3,Pt/C,and Rh/C have been immobilized successfully.The immobilized catalysts are mechanistically robust towards stirring in solutions,and they worked well in diverse synthetic reactions.The immobilized catalyst tablets are easy to handle and reused.Moreover,the metal leaching of immobilized catalysts was reduced significantly. 展开更多
