Existing rechargeable batteries not only fail to meet the demand for high power applications but also cause heavy metal pollution.Li-ion capacitors(LICs),which
Recently,perovskite solar cells(PSCs) have flourished,and their power conversion efficiency(PCE) has increased from the initial 3.8% to 25.2% in 2019,which is an unprecedented advance.However,usually high-efficiency and stable PSCs are small-area devices
Electrocatalytic water splitting driven by electrocatalysts is recognized as a promising strategy to generate clean hydrogen fuel.Searching and constructing hig
The grain surfaces (film surface and grain boundary) of polycrystalline perovskite films are vulnerable sites in solar cells since they pose a high defect densi
We report a simple and effective method to realize desirable interfacial property for inverted planar per-ovskite solar cells(PSCs)by using small molecule ethan
The exploitation of proper electron transport layers (ETLs) and interface optimization can play a pivotal role to promote the performance of organic solar cells
Lithium(Li) metal,possessing ultrahigh theoretical capacity and the lowest electrode potential,is regarded as a promising new generation anode material.However,the uncontrollable growth of Li dendrites during cycling process gives rise to problems as capa
在常压、580~640℃、丙烷体积空速500~2000 h-1条件下,采用自主开发的新型非贵金属催化剂(活性组分为Zr-Ga-W-Co-Fe-Zn,载体为MgO-Al2O3复合物),在微型固定床反应器中考察了其催化丙烷脱氢的性能,并建立了相应的宏观动力学模型。采用多元非线性回归得到了模型参数,其中脱氢表观活化能为153.42 kJ/mol。经计算可知,总反应速率的拟合值与实验值的平均相对误差为3.14%。经相关系数R2和F方差分析表明,所建
