浙江省未来社区终身教育标准体系构建研究

浙江省自2019年正式开展“未来社区”的建设战略以来,着力于探索未来社区九大场景的创新构建。其中,教育场景空间是未来社区构建终身教育体系的载体。本文从标准化视角出发,梳理未来社区终身教育的关键要点,结合浙江省未来社区终身教育发展特点,构建浙江省未来社区终身教育标准体系,从而帮助浙江省各地未来社区扎实推进终身教育建设,进而实现未来社区终身教育作用的最大化,为解决未来社区终身教育遇到的发展难题提供标准化的解决方案。

The effect of the carbon components on the performance of carbonbased transition metal electrocatalysts for the hydrogen evolution reaction

The hydrogen evolution reaction(HER)is a promising way to produce hydrogen,and the use of non-precious metals with an excellent electrochemical performance is vital for this.Carbon-based transition metal catalysts have high activity and stability,which are important in reducing the cost of hydrogen production and promoting the development of the hydrogen production industry.However,there is a lack of discussion regarding the effect of carbon components on the performance of these electrocatalysts.This review of the literature discusses the choice of the carbon components in these catalysts and their impact on catalytic performance,including electronic structure control by heteroatom doping,morphology adjustment,and the influence of self-supporting materials.It not only analyzes the progress in HER,but also provides guidance for synthesizing high-performance carbon-based transition metal catalysts.

腐殖酸复合锆基MOF材料(HA@UiO-66)的制备及其染料污染物吸附性能研究

通过原位生长的方法成功制备了腐殖酸(HA)复合UiO-66的纳米材料(HA@UiO-66),通过SEM、XRD、FT-IR、Zeta电位对其进行表征。将HA@UiO-66用于阳离子染料亚甲基蓝(MB^(+))和阴离子染料甲基橙(MO^(-))的吸附处理,结果表明,MB^(+)和MO^(-)在HA@UiO-66上的吸附过程符合伪二级动力学和Langmuir等温吸附模型;HA@UiO-66对MB^(+)和MO^(-)的吸附容量都大幅度提高,最大平衡吸附量分别为123.3 mg/g和49.6 mg/g,并且表现出对阳离子染料MB^(+)的优先吸附。
