The remarkable properties exhibited by two-dimensional(2D) photocatalytic materials,differing from bulk materials,have captivated significant interest.In this study,a hexagonal-phase ZnIn2S4were synthesized using thiosulfate,thioacetamide,and L-cysteine as sulfur sources(denoted as ZIS-A,ZIS-B and ZIS-C),respectively.The synthesized ZnIn2S4 exhibited varying morphologies and photocatalytic properties,which were characterized through XRD,SEM,TEM,EPR,XPS and so on.The results confirmed that ZIS-B with 2D nanosheets structures exhibited superior photocatalytic properties compared with that of the flower-like spheres and block ZnIn2S4samples.The hydrogen evolution rate of the ZIS-B is 3653 μmol g-1h-1,which is 3.1 times than that of the other samples.This improvement was attributable to that the ZIS-B have 2D nanosheets structures and sulfur vacancies.Notably,the 2D nanosheets structure endowed ZnIn2S4with a larger surface area and abundant reactive sites for efficient evolution reaction.Additionally,the presence of sulfur vacancies served as active sites,facilitating carrier transport and ultimately promoting the rate of photocatalytic hydrogen evolution.These results present a novel method for optimizing 2D ZnIn2S4photocatalyst to improve the photocatalytic hydrogen evolution.

Construction of heterojunction has been considered as an efficient strategy to enhance the gas-sensing performances of metal oxide semiconductors.On this basis,hierarchical In_(2)O_(3)/In_(2)S_(3) microsphere heterostructures were synthesized by partial oxidation of In_(2)S_(3) precursors which were obtained via a facile hydrothermal method.Besides,gas sensors based on the acquired materials were fabricated to investigate their sensing performances toward triethylamine(TEA).The results reveal that the gas sensor based on In_(2)O_(3)/In_(2)S_(3) exhibits a high response of 37 at 300℃ toward 0.45 mg/L TEA,which is 3.7 times higher than that of bare In_(2)O_(3).Meanwhile,it also possesses fast response/recovery time(19 s/154 s),good repeatability,selectivity and long-term stability.The excellent sensing performances toward TEA are mainly attributed to the massive oxygen vacancy defects and heterojunction formed between In_(2)O_(3) and In_(2)S_(3).This work provides a facile temperature-dependent route to controllably synthesize hierarchical In_(2)O_(3)/In_(2)S_(3) microsphere heterostructures,and the In_(2)O_(3)/In_(2)S_(3) sensor shows great application prospects in TEA detection.

Human health is deteriorating due to the effluent containing heavy metal ions and organic dyes.Hence,photoreduction of Cr(Ⅵ)to Cr(Ⅲ)and degradation of rhodamine B(RhB)using a novel photocatalyst is particularly important.In this work,h-BN/NiS_(2)/NiS composites were prepared via a simple solvothermal method and a double Z-scheme heterojunction was constructed for efficiently removing RhB and Cr(Ⅵ).The 7 wt-%h-BN/NiS_(2)/NiS composites were characterized via a larger specific surface area(15.12 m^(2)·g^(−1)),stronger light absorption capacity,excellent chemical stability,and high yield of electrons and holes.The experimental result indicated that the photoreduction efficiency of the 7 wt-%h-BN/NiS_(2)/NiS photocatalyst achieved 98.5%for Cr(Ⅵ)after 120 min,which was about 3 times higher than that of NiS_(2)/NiS(34%).However,the removal rate of RhB by the 7 wt-%h-BN/NiS_(2)/NiS photocatalyst reached 80%.This is due to the double Z-scheme heterojunction formed between NiS_(2)/NiS and h-BN,which improved the charge separation efficiency and transmission efficiency.Besides,the influence of diverse photogenerated electron and hole scavengers upon the photoreduction of Cr(Ⅵ)was studied,the results indicated that graphene-like h-BN promoted transportation of photoinduced charges on the surface of the h-BN/NiS_(2)/NiS photocatalyst via the interfacial effects.

Two-dimensional carbide MXenes(Ti_3C_2T_x and V_2CT_x)were prepared by exfoliating MAX phases(Ti_3AlC_2 and V_2AlC)powders in the solution of sodium fluoride(NaF)and hydrochloric acid(HCl).The specific surface area(SSA)of as-prepared Ti_3C_2T_x was 21 m^2/g,and that of V_2CT_x was 9 m^2/g.After intercalation with dimethylsulfoxide,the SSA of Ti_3C_2T_x was increased to 66 m^2/g;that of V_2CT_x was increased to 19 m^2/g.Their adsorption properties on carbon dioxide(CO_2)were investigated under 0–4 MPa at room temperature(298 K).Intercalated Ti_3C_2T_x had the adsorption capacity of 5.79 mmol/g,which is close to the capacity of many common sorbents.The theoretical capacity of Ti_3C_2T_x with the SSA of 496 m^2/g was up to 44.2 mmol/g.Additionally,due to high pack density,MXenes had very high volume-uptake capacity.The capacity of intercalated Ti_3C_2T_(x )measured in this paper was 502 V·v^(–1).This value is already higher than volume capacity of most known sorbents.These results suggest that MXenes have some advantage features to be researched as novel CO_2 capture materials.

为了解决超临界二氧化碳管道泄漏风险评估问题,基于工业规模超临界二氧化碳小孔泄漏试验结果,提出分别构建超临界泄漏阶段、气液两相泄漏阶段、气相泄漏阶段的理论模型,并通过确定各阶段的传递参数,实现二氧化碳减压过程的理论建模。采用MATLAB软件编制了模型求解程序。通过试验数据验证了理论模型的可靠性。基于理论模型计算结果定量探讨了初始压力、初始温度和泄漏口径对泄漏减压过程压力及质量流量的影响。结果表明:初始压力在8~9.5 MPa变化时,对减压过程压力及泄漏质量流量影响较小;初始温度在33~39℃变化时,压力降至临界值的时间逐渐增加;泄漏口径减小,压降时间显著变长;在泄漏减压初期,泄漏质量流量均出现波动,随后随压力降低而逐渐降低。构建的理论模型能够实现超临界二氧化碳泄漏质量流量预测。

为便于管控不同堆场区域内利用率,传统集装箱港口通常在堆场区域内布置轮胎式集装箱起重机,选择轮胎式集装箱起重机的主要原因是其具备转场灵活的特点,而这一特点又由柴油机的供电方式所决定。然而,由于轮胎式集装箱起重机的作业属性为间歇工作制,故存在能耗高、运行成本高、废气和噪声污染等问题。另外,随着资源问题和环境问题的日益突出,国家在政策面对集装箱港区提出了节能减排的降低指标,对集装箱港区堆场区域有效降低轮胎式集装箱起重机的能耗提出了新的要求。为此,文中就轮胎式集装箱起重机的技术现状,汇总及总结了国内外已有的多种节能技术方案,论述了各项节能方案的技术性、可行性、节能效果及其优劣性,以供相关工程技术人员参考。

山东泰山钢铁集团有限公司(简称泰钢)1号高炉自2019年10月开炉投产以来,炉缸热电偶温度基本保持较低的温度。通过建立一维稳态传热模型计算碳复合砖的残余厚度和热面处保护层的厚度。结果表明,炉缸底部侧壁的碳复合砖侵蚀量较少,炉缸铁口中心线附近碳复合砖侵蚀量较多,高炉炉缸区域未出现“象脚状”侵蚀。高炉炉缸内保护层的厚度随着高度的增加而增大,富铁保护层易在铁口中心线以下形成,富渣保护层易在铁口中心线以上形成。碳复合砖中的主要成分氧化铝几乎不与铁水发生反应,而二氧化硅会与铁水发生反应。铁水渗透进入碳复合砖的临界孔隙为2.030μm,远大于其平均孔隙0.238μm,因此,采用碳复合砖有利于抵抗铁水的侵蚀。
