X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Gongye shui chuli, 2005 采用曝气生物滤池工艺对燕化公司西区污水处理场的二级出水进行了处理，研究了进水NH3-N浓度、COD浓度、m(COD)∶m(NH3-N)、碱度及气水比对NH3-N去除效果的影响。试验结果表明，当进水NH3-N质量浓度小于30mg/L时，曝气生物滤池对NH3-N具有良好的去除作用，平均NH3-N去除率达到90.4%，出水NH3-N质量浓度可降至1mg/L以下。NH3-N去除率随进水m(COD)∶m(NH3-N)的增加而降低；当进水m(COD)∶m(NH3-N)小于2.0时，NH3-N去除率达到90%以上 ...

Advanced Functional Materials, EarlyView.Programmable 2D magnetic clusterphenes are realized through a ligand‐mediated cluster‐assembly strategy. Direct linking of magnetic superatomic clusters enhances electron delocalization and symmetry breaking, enabling the concurrent strengthening of magnetic exchange interactions and spin–orbit coupling.

Multicenter (FX)n/NH3 Halogen Bonds (X = Cl, Br and n = 1–5). QTAIM Descriptors of the Strength of the X∙∙∙N Interaction [PDF]
Molecules, 2017 In the present work an in depth deep electronic study of multicenter XBs (FX)n/NH3 (X = Cl, Br and n = 1–5) is conducted. The ways in which X∙∙∙X lateral contacts affect the electrostatic or covalent nature of the X∙∙∙N interactions are explored at the CCSD(T)/aug-cc-pVTZ level and in the framework of the quantum theory of atoms in molecules (QTAIM ...
