Photocatalytic technology has been widely adopted to address the issue of air pollution. The separation of photogenerated carriers and the activation of reactants on catalyst surface are the main factors that affect the photocatalytic efficiency. Here, the phosphate/potassium(PO_4/K) cofunctionalized carbon nitride(labeled as PO_4-CN-K) was synthesized via a one-step in situ copyrolysis of thiourea and potassium phosphate. The unique electronic structure of PO_4-CN-K could significantly improve the performance of photocatalytic NO purification. The enhanced activity of PO_4-CN-K can be attributed to the promoted activation capacity for O_2. NO and H_2. on the catalyst surface,the decreased of carriers recombination, benefiting from the co-functionalization of phosphate groups on the surface of CN and the construction of K channels between CN layers. The photocatalytic NO conversion pathway is disclosed through time-dependent in situ FT-IR, indicating that PO_4-CN-K can efficiently convert NO molecules into harmless nitrate via the NO→NO+→nitrate/nitrite routes. The research provides a novel strategy to impel the development of photocatalytic technology for efficient air purification.

The assembly of monomicelles along onedimension(1D)to construct tubular or fibrous mesostructures is greatly desired but still ***,we have demonstrated a facile strategy to synthesize 1D bimodal mesoporous metal oxides(e.g.,WO_(3),WO_(3)/Pd,WO_(3)/Pd Cu,TiO_(2.,and ZrO_(2.)nanofibers(NFs)through assembling the organic-inorganic composite monomicelles in a beam stream generated via an electrospinning *** facile and repeatable methodology relies on the preparation of copolymer@metal-complex monomicelles in an anisotropic solution and oriented assembly of them in the beam stream by the selective evaporation of ***_(3)and its derivatives are chosen as the demo,which show a uniform continuous fibrous structure with dual mesopore sizes(~4.0 and 7.6 nm)and large surface area(~93.1 m^(2.g^(-1)).Benefitting from the unique textual structure,gas sensors made by Pd-decorated mesoporous WO_(3)NFs display outstanding comprehensive sensing performance to ethylbenzene,including a high sensitivity(52.5),an ultralow detection limit(50 ppb),and fast response/recovery kinetics(11/16 s)as well as an outstanding selectivity,which render them promising for rapid environmental monitoring.

高温热水解是促进低有机质污泥厌氧水解过程的有效方法,探讨不同含固率下低有机质污泥高温热水解后物质溶出规律,可为实现其高效厌氧发酵提供基础理论依据。通过序批式实验和相关性分析研究了含固率、温度和时间对高温热水解污泥中物质溶出的影响。结果表明:污泥中物质溶出特性与温度、含固率的相关性均较高(P=0.2.2.0.757,0.2.9~0.774)。除含固率6%的污泥外,8%、10%及12.含固率污泥中可溶糖、可溶蛋白质、总挥发性脂肪酸(TVFA)、溶解性有机碳(SOC)浓度随处理温度提高而增大,而pH则相反。除含固率的8%污泥外,氨氮(NH^(+)_(4)-N)和游离氨(fan)浓度亦随含固率、热水解温度的提高而增大。当处理温度相同时,可溶糖、可溶蛋白质、TVFA、SOC、NH^(+)_(4)-N、fan浓度总体上随含固率的升高而升高,而含固率变化对pH无显著影响。同时,含固率6%~10%的污泥中可溶蛋白质的溶出率高于可溶糖,随着含固率的增加,可溶蛋白质溶出率增幅有所降低;含固率为6%和12.时,TVFA增加不明显;SOC与SCOD的变化规律一致,主要取决于可溶蛋白质溶出浓度的变化。
